“I have recently upgraded to SQL Server 2014, but there have been some issues with the application since the upgrade. Now I want to downgrade my SQL database to its previous version. I believe this downgrade will solve the current issues. Sadly, I do not know the process of restoring database from 2014 to 2008. Kindly suggest me an easy method to downgrade 2014 SQL Server.”

Prerequisites to Prevent Disaster During the Process

• This isn’t just a restore or recovery process in a database. Hence, it is beneficial to consider this as a migration process for data in SQL Server 2014 to SQL Server version 2008 and further carry out the process with complete precision. 
• Before initiating the process, it is important to lock the schema and put the source database, i.e., SQL Server 2014 database to read-only mode so that no data is changed or hampered during the migration process. 
• Never run the process directly on the production environment, as any issue or challenge can lead to bigger issues including permanent data loss in the database. It is better to run the commands on a clone database first. 
• To avoid any issues in the future regarding the process and why it took place, it is crucial to document the entire process.

These are some of the best practices database administrators can follow to avoid any disasters during the migration process. 

Method 1: Restore Database from SQL Server 2014 to 2008 Through Generate Script Wizard

In this method, Generate Scripts wizard is used to script the SQL database schema in a higher SQL database version. Then we get connected to a lower SQL Server version and run the script we have generated earlier. Thus, we are able to copy data and successfully restore database from 2014 to 2008.

#Stage 1: First, we have to script AdventureWorks database schema in SQL 2014 Server. To do that, we will use Generate Scripts wizard.

• To begin with, connect to SQL Server instance of 2014 version, In “Object Explorer.” Then right-click on Adventureworks database and expand Tasks. Select the option “Generate Scripts…”.
• Generate and Publish Scripts wizard will open. Skip Introduction screen and go to Choose Objects page by clicking Next.
• On the next page named “Choose Objects”, select Script entire database and all database objects. Click Next.
• On Set Scripting Options page, choose the file name and location where you want the script to be saved. Then click on Advanced button.
• A dialog box called Advanced Scripting Options will appear. You have to change certain options on this box. Set the value True for “Triggers,” “Indexes,” and “Primary Key.” Also set SQL Server 2008 R2 as “Script for Server Version” and Schema and Data as “Types of data to script.”
• Click OK to close this dialog box and get back to Set Scripting Options page. Click Next on that page to proceed with the restore database from SQL Server 2014 to 2008 process.
• On Summary page, review all the selections you have made and then click on Next button to start generating scripts.
• Once the script generation is completed, click Finish to close the wizard.

#Stage 2: Now, we have to run the SQL Script generated in stage 1 and copy data.

• Get connected to SQL Server 2008 in Object Explorer. Open previously saved SQL Server script in SQL Server Management Studio.
• You have to edit the script by specifying correct Adventureworks database data location and log files location. After that, run the script. This will create Adventureworks database on SQL Server 2008 instance.
• Once it gets executed successfully, refresh Object Explorer Database folder. You will see that the Adventureworks database has been downgraded.

Method 2: Restore Database From SQL Server 2014 to 2008 Automatically

It is understandable that most users do not want to go through such complex method. For them, there is an alternate method available in the market.

So let’s dive into the details on the .parquet files and learn why they are difficult to access for the users. 

What makes Parquet Inaccessible on Windows and MacOS?

When we talk about the .parquet files, we are aware to why they are used. But, the question that usually occurs in the user’s mind is whether .parquet file is human-readable or not. Similarly, when they need to open these files on their native operating systems, they might encounter various issues with the same task. Many reasons restrict these files from opening on Windows and Mac OS. Let’s take a look at some of these reasons and learn how they can be resolved to make the files easily accessible on the given operating systems.

• The first reason is that neither Windows and MacOS do not have a native or built-in Parquet reader available. This makes it difficult to open the files on their devices when needed. 
• The next common cause is the structure of these files. The .parquet files are generally encoded and further store the data in binary language. Hence, without decoding these files, users cannot simply open or read these files in Windows or Mac. 
• Parquet files are primarily designed for various analytics and data processing engines, such as AWS Athena, Google BigQuery, Azure Synapse Analytics, and Snowflake. The structure and design of these files are intended for machines, not end-users. 
• The spreadsheet tools like Google Sheets and Excel do not support these files directly, making it necessary for users to convert them to a readable and accessible format first. 

These are some of the common reasons that restrict users from accessing the .parquet files and further trouble them with the doubt how to open Parquet file in Windows or Mac. To understand the issue better, we will now take a look at the challenges that users encounter while dealing with these files. 

Challenges with Parquet File Inaccessibility on Native OS

Below are the challenges that affect and disrupts the user workflow due to unreadability of the files:

• Due to the unavailability of the built – in file readers, users can’t read or open the .parquet file on Windows or Mac devices. 
• The .parquet files are created in Apache. Therefore, they are dependent on the environment for accessibility and other desired operations. Now, this makes it difficult for the users to read the files. 
• The .parquet file uses different compression modes for data manageability. Most of the time, the native file readers do not support these compression codecs, which can further cause issues.
• Parquet file data is mainly structured and complex. Due to the nested structure of the files, the data cannot be interpreted without appropriate tools. 
• In case a .parquet file was created on a Linux platform, it might end up behaving differently on operating systems like Windows and MacOS. 

These are the challenges that affect users’ workflow and disrupt their day-to-day tasks. Now, to make it easier for the users to open .parquet files on the desired operating systems or devices, we will take a look at the methods one by one. 

How to Open Parquet file in Windows & MacOS Manually? Method Explained

There are not many ways that allow users to read the .parquet files and access them as needed. However, the most common method, which includes accessing or reading the files manually, is the online approach. Users often find it more convenient to use an online tool for the task. But, with the ease it offers, there are various risks that come along. Here are some of these reasons why not to go for the online tools: 

• The most common risk associated with the online tools is the security and privacy concerns. Submitting the .parquet files to online reader tools simply means giving access to third-party tools for users’ sensitive and crucial data. This can risk the data being exposed to untrusted sources.
• After adding the data to the online sites, users might lose control and access to their data. As the online tools never specify how long they will store the data, or if they will keep any copies. 
• The next risk is the limitations of the file size and feature support. Not all online tools support large .parquet files. Furthermore, the online tool often fails to support all the features or the nested structure of the Parquet files. 

These are some of the common risks to using the manual approach for data accessibility of Parquet files. In such cases, where anyone can mishandle the data, we suggest using a professional solution. So let’s now move to the next method to learn how to access these files without risking data security. 

How to Read Parquet file on Mac and Windows OS Professionally?

As we all know, the .parquet files are generally unreadable by humans. So to read or access them, it is important to first convert them to a readable file format and then run the desired operations. So, we will now take a look at how we can convert Parquet files to CSV using a professional tool and also learn how the tool works. The solution we recommend is the SysTools Parquet Converter Tool, a utility designed to convert the files easily to 10+ widely used file formats.

Let’s now take a look at the steps of this tool:

1. Install and run the tool. Click on Add Files to add the .parquet file to the software.

Understanding Parquet File Format And It’s Readability

There are many file formats that are used for maintaining and handling large datasets. Parquet file format is one of them. This file format is created in Apache Spark and is widely used with analytics platforms such as Apache Spark, Hadoop, AWS Athena, and Azure Synapse. The .parquet file format is generally is columnar-file format that can efficiently store large datasets and further allows deliverability of high query performance. Let’s now take a look at a few situations where these files are used and then proceed with the reasons that lead to the ‘Is Parquet Human Readable’ question. 

• To process Big Data effectively.
• For data lakes and data warehouses.
• For analytics, BI, and reporting tools.
• Commonly used for analytics for cloud-based platforms such as Azure and AWS.
• As training models for machine learning and handling large datasets.
• Helps the users to move the datasets among Parquet supporting platforms. 

Factors Restricting Parquet File Readability

When it comes to the question, is Parquet human readable, the answer is No. Below are some reasons why the raw Parquet files are unreadable by humans:

• To store the data, Parquet uses a binary data format that is easily readable by machines but not directly by humans. 
• Users often might confuse the unreadability with file corruption, but that’s not the case. 
• Binary coding within the file, embedded metadata, and compression methods in the file format make the data unreadable to users. 
• Despite being unreadable, the data within the .parquet file is still accessible to the users. 
• The .parquet files are mainly used for analytics, and it primarily focuses on scalability, performance, and storage. 

From this, we can learn that the Parquet files are unreadable majorly due to their binary format and not due to errors. Now, after learning the factors, we will learn the best approaches to make the files readable for the users. 

How to Make Parquet Files Human Readable? All Ways Explained

As we learned about the common concern of “is parquet human readable” for the users, it is now time for us to find the best ways to make these files readable. We will take a look at the suitable methods one by one to make them easier for the users to understand. 

Method 1: Change to CSV Format For User Readability

The first method we are going to discuss is changing the .parquet file to a format that is easily readable by the users. In this method, we will convert Parquet to CSV. Below is the command that will help with the same task:

df = pd.read_parquet("input.parquet")
df.to_csv("output.csv", index=False)

With the help of this command, users can efficiently convert the file and read it on platforms that support the CSV file format. Now, moving on to the next method, let’s see how it will help the users to make the files readable. 

Method 2: Transforming to XLS/XLSX File Format

Now, another method to read the specified files is to convert Parquet to Excel file format. This will allow the users to read the files effectively. Let’s now take a look at the command that will help the users with the .parquet file readability. 

import pandas as pd
import pyarrow.parquet as pq
table = pq.read_table("input.parquet")
df = table.to_pandas()
df.to_excel("output.xlsx", index=False)

This command will make it easier for users to read the files in XLS/XLSX file formats. 

However, both the file formats that we discussed are tabular. Also, these methods use commands that can be quite confusing for users who aren’t very technically aware. So, we will now use a professional solution to make the task simpler. 

Method 3: Use an Automated Tool For Parquet File Readability

From the above-mentioned method, we learned how the parquet files can be changed for tabular formats for efficient accessibility and analytics.

SQL Server Attach Database Without Log File – Overview

To understand the attach database without log task, before directly proceeding to the solution section, let us take a real example:

SQL database is one of the most common databases used for every type of business and customer accounting. It is in use by business platforms for the purpose of data analysis, processing of the components, and data integration. The database of SQL Server comprises three file types:

1. Primary Database File (MDF): Master Database Files (MDF) are primary database files, where all the information of database is stored. Data created by the user is saved in ‘Tables’, which has 2-dimensional structures (Rows and Columns). Users can create many MDF files in the database of SQL server. Extension of MDF files is .mdf which is why learning to restore database from MDF file without LDF is crucial.

2. Secondary Database File (NDF): These files are user-defined and optional for store data. It can be used to spread data along multiple disks by putting each file in a different disk drive. When the MDF database exceeds its maximum size, users can use NDF files. The extension of Secondary database file is .ndf extention.

3. Log File (LDF): The transaction log files stores all transactional information of SQL database. There must be at least one log file in each database. Moreover, The log information hold by LDF file, help to recover log information. The file extension of LDF file is .ldf.

Techniques to Attach MDF File Without LDF File

We can attach SQL MDF without Log file and there are multiple manual ways to do so. Therefore, the manual ways as well as the automated ways are mentioned below for users to get the desired results. Using these solutions, users can easily execute SQL Server attach database without Log file task.

Learning the causes will help in giving a clearer insight into the limitations of the Parquet file format. Also, it helps with understanding how changing the format to any other desired format can be helpful for the users. 

• The first reason for this transformation is that the .parquet file format is a binary file that cannot be easily read by users in text editors. This requires them to change the format to a readable format, like .txt, first, and then proceed with their required tasks. 
• As we know, the Parquet file format is generally used to store large data sets. Now, the ETL (Extract, Transform, Load) tools, or even widely used tools like spreadsheets, do not support the file format. Hence, when the users need the data for analytics or report generation, they have to convert Parquet to Text file formats. 
• Another situation where the conversion is required is while sharing the .parquet files. To share the .parquet files directly, the user on the receiving end must have appropriate libraries and the right environments. By changing the files from .parquet to .txt, it becomes much easier to share these files among users. 

Similarly, several reasons demand that users convert these files. Even while migrating Parquet files to Access database or any other database, it becomes crucial to change the file formats first to a desired format and then continue with the process. Let’s now move to understanding the methods that will help with the conversion of the files effectively. 

How to Convert Parquet to Text File Manually?

When we look for the manual methods for the transformation of the .parquet files, there aren’t many available.

The SQL Error Log sounds much like SQL Transaction Log, which keeps a record of database transactions and ensures database integrity, right? Unfortunately, the error Log file is not like that, instead it is a different file and has different functions.

SQL Error Log files are very different from SQL Server LDF. It comprises User-defined events and is used to troubleshoot system problems. In this technical guide, we are going to provide complete information about Microsoft SQL Server Error Log File.

Let’s get started!

Where is MS SQL Server Error Log Stored?

You can easily find the SQL Server error log location for your dedicated SQL Server version. All you need to use the following path to access it.

Drive:\ Program Files \ Microsoft SQL Server \ MSSQLV.SQLEXPRESS \ MSSQL \ Log \ ERRORLOG

It is a general path that provides you SQL Server 2017 / 2016 / 2014 / 2012 / 2008 / 2008 R2 / 2005 error log file location. For example, it is the SQL Server 2016 Error Log file location in Windows 10.

C:\ Program Files \ Microsoft SQL Server \ MSSQL13.SQLEXPRESS \ MSSQL \ Log

How to Change Error Log File Location in MS SQL Server 2017/ 2016/ 2014/ 2012?

Now, we know the SQL Server error log location clearly. However, sometimes SQL users need to update the path of an SQL Server error log file. The overall procedure is classified into two stages.

Stage 1: Start the SQL Server Configuration Manager

One can open the Configuration Manager with different techniques. All of them are mentioned below to fix SQL Server logs & their errors.

Method #1 – To open Configuration Manager, you can type the SQL Server Configuration Manager in the search box of Start and open it as shown in the screenshot.

Method #2 – Else, you can use the following path to reach to the SQL Server error log location by opening SQL Server Configuration Manager.

Here, we opened the SQL Server Configuration Manager with the above–mentioned location in SQL Server 2017.

Method #3 – You can also open the Run dialog box and type ‘compmgmt.msc’ in the box.

From the following screen, expand the Services and Applications section and get the SQL Server Configuration Manager.

Stage 2: Change the SQL Server Error Log Path

Step-1. Under the SQL Server Configuration Manager, go to the SQL Server Services option.

Step-2. Right-click on SQL Server(SQLEXPRESS) as shown in the screenshot and choose the Properties option.

Step-3. From the SQL Server (SQLEXPRESS) Properties, click on the Startup Parameters tab. Afterward, under the Existing parameters section, choose the SQL Server Error Logs file whose location you want to change.

Step-4. The starting prefix (like e,d) and the current Error Log file Name will not change. The rest of the folder can be changed. Mention the new path under the Specify a startup parameter box and update it.

Step-5. The changes to the SQL Server error log location are saved but they are not active. For this. You need to start the SQL Server Services.

Methods to Open SQL Server Error Log Files

There are two ways through which one can view the Error Log. Now, whenever, the SQL Server could not open Error Log file, then use any of the below-mentioned techniques. Also, users need to know that these methods are not advised to how to check error log in SQL Server database.

Approach #1: Use T-SQL to Read SQL Error Log

Connect with the SSMS and type ‘xp_readererrorlog’ in the panel. It is a SQL Server query to read Error Log.

Approach #2: Use Object Explorer Option

Without the help of T-SQL, you can also view the error log. Finally, let’s check out how to read SQL Server Error Log.

Step-1. Open Microsoft SQL Server Management Studio on your system.

Step-2. Time to connect with Object Explorer. Open Connect to Server Window and select the Server name. Afterward, choose the Authentication Type and click on Connect.

Step-3. Go to the Management section from the Object Explorer in order to read SQL Error Log.

Step-4. Expand the Management Section and go to the SQL Server Logs.

Step-5. Right-click on SQL Server Log option. Go to the View option and select SQL Server Log from the menu to view SQL Server error log.

Step-6. The Log File Summary will appear on the screen. From the same window, you can opt for different Log – SQL Server Agent, Database Mail.

That’s all about Microsoft SQL Server Error Log.

Automated Solution to Read, Examine & Learn How to Check Error Log in SQL Server

Well, the manual method works, but not all the time. The success ratio here is quite low. Evidently. experts recommend users opt for an advanced automated solution. Evidently, this is exactly why experts recommend the automated solution.

Moreover, if you want to examine the SQL Transaction Log file, then you can try SysTools SQL Log Analyzer Software. Download this tool & then simply follow the instructions below to read & examine your SQL error log files.

Step-1. Launch the Software & then Click on the Open button to add LDF log files.

How to Check Error Log in SQL Server with T-SQL Method Manually?

We can also use the SERVERPROPERTY() command to get the SQL Server error log location at the moment. However, while executing the queries, users need to be very careful. This is because learning how to check error log in SQL Server using query commands can be risky & might result in data loss.

 SELECT SERVERPROPERTY('Name_of_Error_Log_File') AS 'Error log file location';

After executing the queries, users can browse in the directory to find the records. They can see the error logs there without any hassles.

• ErrorLog: Error log file at the moment.
• ErrorLog.1: Error log file 1 of the archive
• ErrorLog.2: Error log file 2 of the archive

Drawbacks of the Manual Method to View SQL Server Logs

Now, these manual solutions are full of shortcomings that can be highly dangerous for users’ log files. We are aware of how crucial a Log data file in SQL Server is. How it helps in tracking all the transactions & the user who executed that is what we learn from it.

Let’s quickly have a look at the manual method drawbacks in depth:

• Very Poor Interface: The interface of the manual solutions is very poor. The T-SQL commands are not interactive at all & spoils user experience. Moreover, when we talk about the SSMS Method, it’s not also that good.
• No Technical Expertise: These manual solutions require more technical proficiency than just the basic knowledge. This makes this task more complex & hard to execute. Also, it’s true that users might be needing SQL experts’ assistance for such methods.
• Lack of Customization Features: For every single task, there is a long command. There are no features for getting the customised results just like what users need. Moreover, users must understand that they can’t get the exact results as expected everytime.
• Security Standards: There is no protective layering if users are opting for such manual methods. However, the automated solution keeps the original file intact to avoid any corruption or data integrity issues.
• Interrupts Business Hours: To find the errorlog SQL Server with manual solutions, users need to be prepared for long time consuming tasks. This can reduce efficiency & even interrupt the usual working hours of the business.

Conclusion

Finally, after understanding all the core concepts of SQL Server error logs carefully, it’s time for us to conclude this article. Also, we know the best ways as well to open, read & check SQL error logs in a smart manner.  The above-mentioned manual & automated solutions are good enough for users to get the desired results they want.

However, when we dig deep, it’s very easy for us to say that manual solutions are a bit complex. Therefore, as per experts’ opinion, the automated tool is the only reliable option left which makes the task hassle-free.

The Two File Formats Explained 

When we talk about these file formats, it is important to understand their basic structures first. Beginning with the Parquet file format, it is a columnar file format that is mainly used to store big data. The Parquet file format generally stores data in column format, rather than rows. This file format is generally created in Apache Spark and is unreadable to humans until converted to a readable format.

On the other hand, YAML file format is a plain-text and human-readable file format that is used for data representation and for configuration files. The YAML file format offers clarity and an editable format. This difference between these file formats demands the transformation of Parquet to YAML. Now, to understand the situations better, we will take a look at a few reasons for this format change. 

Reasons to Convert Parquet to YAML File Format

Here are some of the common reasons that require them to change the Parquet file format to another format.

• Converting the Parquet file format allows users to change the text and data from an unreadable format to a readable format. This helps users analyse and access the data more efficiently and conveniently.
• There are several applications like Kubernetes, that only accept YAML file formats for operations. This becomes another reason to convert Parquet file to YAML.
• As we know, the .parquet file format isn’t a human-readable format, so when it comes to sharing the data with teams, it becomes important for the users to convert the files first and then share. 
• Even though the technical users might understand the issues with accessing Parquet files, when it comes to non-tech users, it becomes much more complicated for them. Hence, changing the file format to YAML allows them to access the files easily. 

Due to these reasons, it often becomes crucial for the users to convert the files. We will now proceed with the methods on how to carry out this conversion safely and securely. 

How to Convert Parquet to YAML Format Easily? Top Ways Explained

If we go looking for any direct manual method for this conversion, there are only a few available. The methods found are either indirect conversions, requiring the files to be changed to a generic file format first, like Parquet file convert to CSV and then converting them to YAML file format, or require technical expertise for coding. Here, we will first take a look at how this conversion is made using Python Pandas.

Method 1: Parquet to YAML File Convert Using Python

The command given below will allow you to make the conversion efficient. This command works in phases. Let’s understand these phases first and then move to the code.

1. The first phase of the code imports the libraries: pandas for data manipulation and further handling .parquet data as a Dataframe, and the yaml library is imported to categorize the Python objects to YAML format. 
2. Next, the Parquet data is loaded into the dataframe to be converted efficiently. 
3. The dataframe containing the data is then converted to a standard structure of Python.
4. The data is then converted from dataframes to a list of dictionaries. Here, each dictionary is a representation of a row in the dataframe. 
5. Next, it is time to write the data in YAML format. The code opens a YAML file with a write operation. 
6. Lastly, the list of dictionaries is converted to a YAML-formatted structure and further written to the opened file. 

After understanding the code theoretically, let’s now take a look at the code that will help with the Parquet to YAML transformation.

import pandas as pd
import yaml
df = pd.read_parquet("input.parquet")
data = df.to_dict(orient="records")
with open("output.yaml", "w") as f:
    yaml.dump(data, f, sort_keys=False)

With the help of this code, users can change the file formats from .parquet to .yaml effortlessly. 

However, there are certain limitations to this method. We will take a look at these setbacks to understand the issues and then find better ways for the conversion. 

Limitations of the Conversion Method Explained

• The .parquet file format is a file format designed to store large datasets in a compressed way. However, after the conversion, the YAML file can become very large. 
• The pandas library in Python cannot maintain or preserve the structures or hierarchy of the Parquet files after the conversion. 
• The data types of the Parquet file format may not be converted accurately to YAML format. 
• When the .parquet files are loaded within Python memory, the memory usage increases. It can further result in errors regarding memory spaces or performance degradation. 

So, to deal with these challenges and then make the conversion effective and smooth, it becomes important for the users to go for a professional method. We will now discuss and learn how the professional solution can be helpful for the users.

Method 2: Convert Parquet to YAML Using Expert Solution

With all those limitations in the manual method, it becomes important for the users to go for a reliable and trustworthy solution. To make the conversion efficient, users can go for a dedicated converter like SysTools Parquet File Converter Tool.

This solution is an optimal way to convert the files without compromising the data integrity or originality. We will now take a look at the steps to using this software.

1. Install and launch the expert utility. Click on the Add Files option to load .parquet files.
   
2. After adding the desired files, click on the Next Button.
3. Then, choose the desired file format, YAML in this case, from the given export options.
4. Enter the destination path to save the resultant file to the desired location.
5. Click on the Export button for Parquet File to YAML transformation. A file report will be generated and displayed after conversion.

By following these simple and quick steps, users can effectively convert the files without worrying about losing data integrity or data structure. This utility ensures the entire data is converted while maintaining the data types and hierarchy.
