SQL Server is another powerful RDBMS that has been around since 1989 and hardened by thousands of enterprise deployments. It supports SQL (Structured Query Language) for querying and manipulating data. It also has advanced enterprise features to ensure scalability and high availability options that reduce downtime for critical applications, including database mirroring, always on availability groups, and failover clustering. 

In addition to the above features, SQL Server also provides a wide range of tools dedicated to business intelligence and reporting: SQL Server Reporting Services (SSRS) for report creation, SQL Server Integration Services (SSIS) for seamless data integration, and SQL Server Analysis Services (SSAS) for performing data mining and analytical activities.

  • After providing all the mandatory details, click on NEXT SAVE AND PUBLISH.

Estuary Flow will proceed to extract, convert, and load data from MySQL into SQL Server in just a few clicks.

Method #2: Manually Load Data from MySQL to SQL Server Using SQL Server Management Studio (SSMS)

In this method, you manually extract data from MySQL tables and save them as CSV files. Then, you transform the data and upload it into SQL Server..

Step 1: Extract MySQL Data into CSV Files

There are several ways to extract data from MySQL to CSV files, including:

  • Using the Command Line
  • Using Mysqldump
  • Using phpMyAdmin
  • Using the CSV Engine
  • Using MySQL Workbench

In this guide, we’ll extract data into CSV files using the command line approach. For in-depth steps of alternative methods, please refer to MySQL to CSV: 5+ Ways to Export Data article.

Using the Command Line

  • Open the command prompt and connect to the MySQL server.
  • Once you’re connected to the MySQL server, your command prompt will look like this:
plaintext
mysql>
  • Select the specific database with the use command and table with the Select command that you want to export in the CSV file format.
  • To export the table into the CSV file, you can use the INTO OUTFILE statement. Here’s an example. 
plaintext
SELECT * FROM table_name INTO OUTFILE 'path_to_csv_files/filename.csv';

Replace table_name with the MySQL table name and path_to_csv_files/filename.csv with the actual path and file name where you want to save the CSV file.

  • You can use the SELECT and UNION statements in the above code to include column headers in your CSV file.
  • Once you have executed the above query, check if the CSV files are generated correctly with the specific MySQL table data.
  • Repeat the entire process for each table.

Step 2: Data Transformation

Once the CSV files are downloaded to your local machine, perform data transformation. This might include:

  • Removing duplicate rows or records
  • Handling missing or null values
  • Standardizing inconsistent data formats
  • Data mapping or data type conversion, if needed
  • Verifying the need for special characters
  • Validating data for predefined rules, and more

Step 3: Import CSV Data into SQL Server

You can export data to SQL Server either by using the SSMS tool or by using the sqlcmd interface. In the following steps, you’ll get to know how to transfer CSV files into SQL Server using SSMS.

  • Install and configure a new SSMS. If you already have SSMS installed, establish a connection to your MySQL instance.
  • Create a new database or open the existing one.
  • Expand the Databases. Choose your database, right-click on it, and then select Tasks Import Flat File.
MySQL to SQL - SSMS
  • You’ll be directed to the Import Flat File window. On the Specify Input File tab, click Browse and mention the path to your CSV file. Enter a table name in the New table name field. When you create a new database or table in SQL Server, the dbo schema is automatically generated. By default, SQL Server sets dbo as the default schema when no specific schema is explicitly mentioned. Click on the Next button.
  • On the Preview Data tab, you will see the preview of your CSV file data in tabular format for the initial 50 rows. Ensure that all columns have been added correctly. Confirm the structure and proceed by clicking Next.
  • On the Modify Columns tab, validate the schema. If the schema is not accurate, you can change it according to individual columns. This includes altering their Data type, assigning a Primary key, and specifying whether null values are allowed. After configuring all the necessary values, proceed by clicking on the Next button.
  • Click on the Finish button to begin the replication process.
  • After the transfer process is finished, you’ll see the Operation Complete message in the Result window.
  • Click on the Close button. Following this, refresh the database and access the newly created table under the Tables section.
  • Right-click on the table name and click on Select Top 1000 Rows. Here, you’ll see your MySQL data is copied into the SQL Server table.

The manual approach offers flexibility and is best suited for infrequent data transfer, one-off, or backup scenarios. But it comes with several limitations:

  • Time-Consuming: In the above method, you would need to repeatedly perform the extraction, cleaning, and loading process for each table. This manual intervention can be burdensome, time-consuming, and error-prone when dealing with large-scale data transfers.
  • Lack of Automation: The manual method lacks automation and real-time data synchronization capabilities. For example, e-commerce platforms require up-to-date inventory details. If the transfer frequency is suddenly increased, manually exporting and importing CSV files becomes an impractical approach. As a result, this makes it less efficient for real-time data integration needs.
  • Scalability: As your organization's data increases over time, the size of datasets you need to transfer can increase. When using SSMS and CSV-based approach, you might face challenges related to storing and managing these large datasets.
