How to convert all tables from MyISAM into InnoDB?

Question

I myself know that I can use an alter table individually to change the table storage from MyISAM to the InnoDB.

But I am thinking if there could be any way to quickly change all of them to InnoDB?

Answer 1

This following code will help you with that:

<?php
    // connect your database here first 
    // 

    // Actual code starts here 

    $sql = "SELECT TABLE_NAME FROM INFORMATION_SCHEMA.TABLES
        WHERE TABLE_SCHEMA = 'your_database_name' 
        AND ENGINE = 'MyISAM'";

    $rs = mysql_query($sql);

    while($row = mysql_fetch_array($rs))
    {
        $tbl = $row[0];
        $sql = "ALTER TABLE `$tbl` ENGINE=INNODB";
        mysql_query($sql);
    }
?>
