Cal,

thanks so much for the reply. I too ran into a similar problem but solved
differently the SQL problem. But I got stuck in the mysql5 and hibernate
interactions. What dialect did you use? Any special tweaks you made to
allow for the current hibernate and mysql5 to get along?

Thanks!

Hi michael we are currently using grouper with mysql 5

it mostly works with the exception that the table "grouper_attributes" doesn't get created becuase hibernate tries to create something mysql5 is not happy with. The long term solution would be an upgrade to the latest hibernate which has a mysql5 dialect, but that would be non trivial.

A work around is to manualy create the table then it will work fine, something like the sql below will do it. Be warned though most of the build process likes to empty out the database and recreat the tables so you can loose the table several times. I've taken to keeping a copy of the table called grouper_attribute_copy and copying it back to grouper_attributes whenever the build process stomps on the origional

mysql5 compatable grouper attributes creation sql:

CREATE TABLE IF NOT EXISTS `grouper_attributes` (
`id` varchar(128) NOT NULL,
`group_id` varchar(128) default NULL,
`field_name` varchar(32) NOT NULL,
`value` text NOT NULL,
PRIMARY KEY (`id`),
UNIQUE KEY `group_id` (`group_id`,`field_name`,`value`(255)),
KEY `attribute_value_idx` (`value`(255)),
KEY `attribute_group_idx` (`group_id`),
KEY `attribute_field_idx` (`field_name`)
) ENGINE=MyISAM DEFAULT;

One day i might get round to seeing if an innodb table type improves performance but for now MyISAM in acceptible (performace experience email to follow once we've done some more testing)

hope this helps

Has anyone gotten Grouper and MySQL (5+) to work together? If so,
please let me know?

Thanks
