If the value provided is not appropriate for the application, perform the following steps before calling DBCHCL:
- Set Change-options to 'Y'.
-
Change the value for Return-time as follows.
If time stamps are... Then change the value for Return-time to... to be provided Y not to be provided N
When time stamps are specified for the Fetch function, the time stamps provided are only valid on the first call to DBCHCL for the Fetch function. The time stamps may be changed later, for instance, if DBCHCL exchanges information with the Teradata Database to keep the response buffer stocked.
It is recommended that only diagnostic applications use the time stamp capability.
The Fetch, Rewind, End Request, and Abort functions read and use the value of Return Code, but do not store it.
