Migration of SQL Server to MySQL Database


Everyone who intends to move their database from SQL Server to MySQL need to determine if the performance and durability of the system in handling the migration process to minimize the system down time. Additionally, it is important to make sure that all data and properties has been converted correctly to prevent loss of data or corruption. Software market offers wide variety of unique tools to automate MS SQL to MySQL conversion. The products can copy all database objects in the source database management system to the target including table structures with all of necessary attributes (defaultvalues, nullflag, etc), data, indexes, foreign keys and views.

High standard of SQL Server to MySQL converter must offer such fundamental capacities as:

  • High performance of database migration
  • Support of all versions of Microsoft SQL (including Azure SQL) and MySQL
  • Support of all modern platforms
  • Command linesupport
  • Support for Unicode
  • User-friendly interface
  • Complete install and uninstall support

Among such migration tools is the SQL Server toMySQL converter developed by the Intelligent Converters. They specialize on providing the best database conversion and synchronization tool since2001. The database migration tool available through them has the capabilities listed above.

If there is no direct link with the destination MySQL (as a result of security reason or virtual hosting limitation), this software can export the data into SQL script file. After this, the SQL Server database can then be exported into the local file containing SQL statements to set-up tables with all indexes and constraints and fill all of them with the data. Later the database administrator or any other related person can import this file to MySQL server while using the standard tools like php My Admin or command line client.

Special migration projects can require copying of partial data from or merge multiple tables into a single one. MSSQL to MySQL converter can process result of SELECT queries running against SQL Server database for all those migration projects.

If a user must customize table definitions during migration, this software has the capabilities to provide feature generally known as “custom column mapping”. This function enables you to change name, type, default value and NULL-attribute for virtually every column of SQL Server table and assure move particular columns from conversion.

To make migration process a lot more flexible, the converter allows to specify MySQL table type (ISAM, MyISAM, HEAP, InnoDBor BDB) and char set for text columns in the destination database.

When calculating the conversion performance, it is recommended to evaluate the database volume, complexity of table structures and resources. The standard speed of conversion available from MS SQL to MySQL tool is around 10000 of records per second on a modern system.

Lastly, this software convert SQL Server views into MySQL format as ‘CREATE VIEW’ SQL-queries with support for more than 90% of possible syntax patterns including embedded MS SQL functions without direct equivalent in MySQL including: DATEPART, DATENAME, STRING_AGG, TRANSLATE, etc. Note, that SQL Server APPLY operatoris not supported in views.
