In a CMP entity bean, call to any create method ( default using primary key or with any other list of parameters ) fails , giving this error :
javax.ejb.CreateException: [Microsoft][ODBC Microsoft Access Driver] Syntax error in INSERT INTO statement.
I've doubly checked for mismatch between types of database columns & parameters passed, but there is no difference. ( Another BMP bean uses same types and it's working perfectly )

Interestingly, the 'finder' & other business methods are working without any problem.
The server is SilverStream 3.7.3 on Win2K.Any idea how this can be solved ?
