Submitting the Startup Request
The sequence of operations for submitting the startup request is:
1 Call DBCHCL for DBFRSUP
2 Check that return code is zero
A return code of zero does not imply that the Teradata SQL request was successful. It does imply that the request has been sent to the Teradata Database, that is, the initial status is successful. If the request is successful on the client, the Teradata Database processes it and sends the first portion (buffer-full) of the Teradata SQL response to the client. To verify that the request was successful, call DBCHCL for DBFFET and check that the first parcel in the response stream is not an Error or Failure parcel.
