[JBoss-user] JBoss CMP/Sybase limitation

2002-12-10 Thread Robert Martin
Hi - Sybase ASE has a limitation of 250 ANDs/ORs in a select. It also has a limitation of 250 elements inside of an IN. We've encountered a problem with the way that JBoss CMP pulls large sets of data from the database because of this limitation. CMP engine first pulls all of the primary keys
