How You Can Use LongByteObject and LongVCharObject Methods
The LongByteObject and LongVCharObject system class methods that access the database (FetchFromDB and UpdateInDB) indicate errors in the following ways:
• The return value is set to a nonzero error code if the method does not execute successfully.
• The DBSessionObject attributes ErrorNumber and DBMSError are set to the appropriate error number if a DBMS error occurs during the execution of the method.
