Bulk Conversion of MyISAM Tables to InnoDB: A Comprehensive Guide

Introduction

Modifying tables from MyISAM to InnoDB one at a time can be tedious. The following article provides a comprehensive solution to quickly convert all MyISAM tables in a database to InnoDB using SQL.

Detailed Solution

To achieve this bulk conversion, execute the following SQL statement:

SET @DATABASE_NAME = 'name_of_your_db';

SELECT CONCAT('ALTER TABLE `', table_name, '` ENGINE=InnoDB;') AS sql_statements
FROM information_schema.tables AS tb
WHERE table_schema = @DATABASE_NAME
AND `ENGINE` = 'MyISAM'
AND `TABLE_TYPE` = 'BASE TABLE'
ORDER BY table_name DESC;

Make sure to replace name_of_your_db with the name of your database.

Implementation

After running the SQL statement above, the output will provide a list of SQL statements that convert each MyISAM table to InnoDB. Copy these statements into a new SQL query window and execute them. This will execute the conversion for all MyISAM tables in your database.
