When planning a database migration from SQL Server to MySQL, it is critical to ensure that the conversion process runs smoothly and reliably in order to prevent data loss or corruption and minimize system downtime. There are many specialized software tools meant to streamline the MS SQL to MySQL conversion process. These tools migrate all database objects from the source database management system to the destination database management system, including table definitions with required characteristics (null flag, default values, etc), data, indexes and constraints, and views.
Advanced SQL Server to MySQL database converters should provide the following essential features:
- Ensure that database migrations go smoothly
- Compatible with Microsoft Windows 7/8/10
- Support for all MS SQL (including Azure SQL) and MySQL versions
- Ability to integrate and synchronize existing MySQL databases with data stored in MS SQL
- Support for automation and scheduling through the command line
- Unicode support
- Simple to use interface
- Complete installation and uninstallation assistance
One such migration tool is the MS SQL to MySQL converter created by Intelligent Converters, a software firm founded in 2001 that specializes in database conversion and synchronization. This database converter has all of the aforementioned features, as well as the following additional benefits:
- In instances when the MySQL server does not allow remote connections, the software may export the data to a SQL script file. MS SQL data is exported to a local file containing data definition (DDL) statements for the purpose of creating tables with the necessary indexes and constraints and populating them with data. Later database administrators will be able to import this file into the MySQL server through conventional tools such as phpMyAdmin.
- Occasionally, it is necessary to convert just a portion of a table’s data or to integrate data from numerous tables into a single one. To accomplish these goals, the MSSQL to MySQL converter enables the conversion of the results of SELECT queries executed against the source SQL Server database.
- If the column name or type of a column in the final database has to be changed, the converter includes a tool called “custom column mapping.” This feature enables you to modify the name, type, default value, and NULL-attribute of any column in a Microsoft SQL table, as well as to exclude certain columns from conversion.
- The converter enables you to pick the kind of MySQL table you want to convert: ISAM, MyISAM, HEAP, InnoDB, or BDB.
When considering conversion performance, it is vital to consider the size of the source database, the complexity of the table structures, and the system resources available. On contemporary hardware, the typical speed of the conversion given by the MS SQL to MySQL tool is roughly 10000 records per second.
