RE: Converting to InnoDB?
Yes, but your myIsam Tables stay myisam ones. After restarting, you must change them to innodb by : Alter table toto storage=innodb. For new tables, they will have innodb storage.

We are running MySQL on Red Hat Enterprise Linux 3, using the Red Hat- supplied RPM file mysql-server-3.23.58-2.3. Our current MySQL configuration has MyISAM as the default database file type.

RE: Converting to InnoDB?
Sorry, Alter table toto ENGINE=innodb. You don't must, you can. You can also have differents storage ENGINES in the same mysql database. With innodb, you will earn ROW level locking.

InnoDB does not support FULLTEXT index. Have you thought about breaking your table into two tables, one in MyISAM with just the FULLTEXT columns and one in InnoDB for the rest of the table? -jsd- -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
