SQL Server to MySQL

MSSQL-to-MySQL is a program to migrate SQL Server databases to MySQL, MariaDB or Percona server. Depending on privileges on the target server user can either migrate MS SQL data into new database or overwrite the contents of an existing MySQL database.

Features Works with all versions of MS SQL, MySQL, MariaDB, Percona, Azure for MySQL, Amazon RDS, ClearDB Migrates table definitions, data, indexes, foreign keys and views Option to export SQL Server database into MySQL dump file Option to merge or synchronize existing MySQL database with MS SQL data Option to customize resulting table structure Option to filter data using SELECT-queries Command line support Stores conversion settings into profile Quick Launch The product can be customized according to customer requirements Unlimited 24/7 support service 1-year subscription for updates

Video Demonstration

Limitations

• Does not convert stored procedures/functions and triggers (our specialists can convert these objects manually as Database Migration Service)
• MS SQL APPLY operator is not supported in views
• Demo version converts only 50 records per table
• Demo version does not convert queries/views and foreign keys

Requirements

• MS SQL environment (server or client components of MS SQL must be installed on the same machine where you run MSSQL to MySQL converter from)
• Necessary privileges to write into the destination database
• Supported OS: Windows XP(SP2 or SP3)/Vista/7/8/10, Server 2003/2008/2012/2016, Linux with WINE

Quick Launch

Once you stored conversion settings into profile you can run the program in Quick Launch mode. Just launch Windows Explorer and double-click on the profile description (.m2s) file with left mouse button. This will cause MSSQL-to-MySQL wizard to launch conversion loading the necessary settings from the specified profile. Then you will be taken right to the screen with progress of conversion without entering all conversion settings.

Synchronization

SQL Server to MySQL converter implements synchronization as combination of inserting MS SQL records that are missing in MySQL table and updating existing MySQL records with MS SQL data. For synchronization purpose source and destination tables must have identical structures and have primary key or unique index defined. It can take some time since the program scans entire source and destination tables in order to find all rows that have been changed.

If you need more options to configure the synchronization or want to reduce duration of the process via "incremental" technique, take a look at MSSQL-MySQL Sync, special product to synchronize MS SQL and MySQL databases.

Converting views

SQL Server to MySQL converter supports about 90% of syntax constructions involved into MS SQL queries. Some of the conversion rules are described into this whitepaper. Below there is example of conversion results for the query with few calls of MS SQL embedded functions having no direct equivalent into MySQL:

Here is how it looked into Microsoft SQL:

And this is the resulting view in destination MySQL database:

MySQL dump file

SQL Server to MySQL converter can migrate SQL Server database into MySQL format even if there is no connection to MySQL server available. Following this way, the program exports MS SQL data into local MySQL dump file instead of migrating to MySQL server directly. The resulting file contains MySQL statements to create all tables and to fill them with the data. Click here to learn how to import dump file into MySQL database.

Virtual Server users option

When using Virtual Server hosting customers may not have sufficient privileges to create new databases on the target MySQL server. For this case we recommend the following approach:

1. ask your Virtual Server administrator to create blank database on MySQL server
2. run SQL Server to MySQL converter and select this database as the target of migration
3. select "Overwrite existing tables only" option when the program asks how to process existing MySQL database

When you complete these steps, the entire contents of the source MS SQL database will be imported into the specified MySQL database.

Customize table structure

This feature can be accessed by double click on the corresponding table name in "Selected tables" list of "Step 5 of 7" wizard page.

This will cause the following dialog box to appear:

To customize type mapping select the appropriate item in the listview on the left and specify new name, type and default value for the field using "Field info" group of controls. Please note that listview on the left contains column attributes of the original types mapping, new custom types and attributes will be displayed in "Field info" controls when the corresponding item is highlighted in the listview.
