Other databases have that problem too. I think the issue is actually that our PK names are too long and db2 is truncating it down to a non-unique version. Normally, I think it is PK_DATABASECHANGELOG and PK_DATABASECHANGELOGLOCK

It would be very nice if you could name the key constraints differntly. On iSeries there will be an error when you create PK_DATABASECHANGE more than one time. On other DBs, the name is ascociated with the table where the key is for, but not on iSeries. There we have a common pool of names for all tables! --- regards Marc Logemann http://www.logemann.org http://www.logentis.de Am 01.06.2009 um 22:40 schrieb Voxland, Nathan: > If you are interested in adding support, that would be great.
