JDD: Driver Locale | Handles | Data Sources | Data Driver | Error Messages | API: Connect Read Update Create Bulk Insert
The data driver verbs that open and close connections, and send SQL statements, all return a number. Typically, if the number is positive, it is a handle. If the number is 0, it means the operation completed successfully (but the function returns no handle). If the number is _1, it means there was some error. You can get more information about the errror using dderr.
For example, try closing a non-existent statement handle:
ddend__db 42 _1 dderr__db'' ISI04 Bad statement handle
