Migrate from MyISAM to InnoDB

My topic for today was to migrate a MySQL server with some databases on it from MyISAM to InnoDB. In the end (after having some backups, of course), I wrote the little script below:


for database in $(echo "show databases;" | mysql); do
  case $database in
      echo "Skipping database $database"
      echo "Converting database $database"
      for i in $(echo "show tables;" | mysql $database;); do 
        case $i in 
            echo "....converting $i"
            echo "ALTER TABLE $i ENGINE = INNODB;" | mysql $database;

Just remember to have a file .my.cnf in your home directory containing the username and password of your database administrator.
