In general the answer is "yes" because there is no precise mapping between SQL types and CL types. For example, there is no easy CL way to represent VARCHAR(n) in CL because the type (STRING n) means strings is exactly length n rather than at most length n. I think it might have been an unfortunate design choice for Common SQL to use the :TYPE slot option to specify the db-type. -- Martin Simmons Email: [email protected] Xanalys Ltd, Compass House, Vision Park TEL: +44 1223 257944 Histon, Cambridge CB4 9AD, England.
