    Change? Why the hell anyone would like to change MyISAM to InnoDB?

    Hello there,

    This contribution looks really good. I noticed on our site, that we get the following error, at which point it stops doing its thing. Not sure if I can just change the FULLTEXT entries manually to get rid of the error.

    1214 The used table type doesn't support FULLTEXT indexes
    in:
    [ALTER TABLE zen_configuration ENGINE = InnoDB]
    If you were entering information, press the BACK button in your browser and re-check the information you had entered to be sure you left no blank fields.
    Regards,

    I'm sorry, I completely forgot that InnoDB tables don't allow FULLTEXT indexes. I'll try to upload tomorrow new version of this contribution that will ignore tables with FULLTEXT indexes.

    Ok, v.1.1 is available from the same address:
    Change Storage Engine v1.1

    It'll ignore MyISAM tables with FULLTEXT indexes.

    http://www.mikebernat.com/blog/MySQL_-_InnoDB_vs_MyISAM

    Note note note: innodb uses 5 or 6 times more space than myisam

    myisam is usually faster for "select", so some tables should stay the way they are now. Log tables etc should be converted to myisam.
    I no longer provide installation support on forum for all my modules. However, if there are real bugs with the modules please feel free to contact me

    At least so it is said. In practice, all recent test I've seen show that InnoDB is faster in selects then MyISAM.
    Have You found any tests that suggest that myisam outperforms innodb?
    Also, I'm curious about this '5 or 6 more space' thing. I've checked my tables and innodb usually takes up to 50% more space.

    As for log tables, one should consider Archive storage engine (introduced in MySQL 5) instead of MyISAM.

    It seems the site runs faster, possibly just psychological though.

    Hello,

    I recieve the following error when i click "change storage engine"

    1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'TABLES WHERE Table_type LIKE 'BASE TABLE'' at line 1
    in:
    [SHOW FULL TABLES WHERE Table_type LIKE 'BASE TABLE']
    If you were entering information, press the BACK button in your browser and re-check the information you had entered to be sure you left no blank fields.

    It this because the script is not compatible with my sql version ?

    I use mysql 4.1.22
    PHP 5.2.11

    Any suggestions ?

    Regards,

    Martijn
