Hi Eivind, Wouter, I originally thought the same thing Wouter as far as the AUTO only being an Integer or a Long, however that is not always the case. I do have one test application that uses the 'GUID' pattern where the auto-generated (although application-supplied in this scenario) key is actually a String. GUID is something like the server name, the time, and the network address hashed together in a 32-bit char, can't remember exactly, but is a use-case for GENERATOR-type that is a String.
Having said that, the GUID pattern is probably a new GENERATOR type not yet defined and does not match the definitions provided for these types (including the AUTO type): http://www.caucho.com/resin-3.0/ejb3/cmp-table.xtp * NONE - no auto generation for this field * IDENTITY - the database supplies the new key, e.g. auto_increment, SERIAL, or IDENTITY * SEQUENCE - use a SEQUENCE type to generate the key * TABLE - use a @TableGenerator for the key * AUTO - choose the generator based on the database o MySQL - IDENTITY using auto_increment o Resin - IDENTITY using auto_increment o Postgres - SEQUENCE o Oracle - SEQUENCE So, from a more educated standpoint, AUTO is designed to be underneath only IDENTITY/SEQUENCE, so yes, AUTO *should* only work if the field is an Integer/Long (unless SEQUENCE can also handle others). Regardless, is there something I can put in the preference file to set the per-table generator to NONE? If not, I'll start poking around to figure it out and commit it back. -D > Hey, > > I'll be adding functionality to choose generator type for > each table.
