Ok, I looked at the Grouper DDL code, and it is not hard to have this type of exception for mysql.  So I went ahead and put a fix in for this.

 

If mysql, I put the index on values at the first 333 chars.  If not mysql, it does what it used to do.  No problem. It works for me on mysql and oracle.

If you want to try it out, that would be good (Grouper HEAD).

 

Regards,

Chris

No, but I think for this index 50 is fine (since the first 50 chars generally gives you the value), and its not a unique index… J  so 333 should be good for all too.

That's not good.  My mysql works fine, but I think it automatically tells the index to only use the first part of the col.  i.e. try this and see if it works:

CREATE INDEX attribute_field_value_idx ON grouper_attributes (field_id, value(767));

http://dev.mysql.com/doc/refman/5.0/en/create-index.html

 

Yes, works.

 

I only have 5.0.45, but it is windows...

I wonder if we should change ddlutils to account for this...

 

Does ddlutils check the charset ? max=333 for utf8 and max=1000 for latin1 AFAIK
