Different IBM relational database products do not always produce the same SQLCODEs for similar errors. Even when the SQLCODE is the same, it may be accompanied by tokens that are specified differently. (The token list is passed in the SQLERRMC field of the SQLCA.) By default, DB2 Connect maps SQLCODEs and tokens from each IBM host or AS/400 database server to the appropriate DB2 UDB SQLCODEs.
