A return code of zero from DBCHCL for the Initiate Request function indicates that the client has sent the request toward the Teradata Database.

If DBCHWAT is used, a return code of zero indicates that a portion of the response to some request has been received from the Teradata Database; and a return code of zero from DBCHCL for the Fetch function indicates that the software has set a pointer to the next information in the response buffer. No one return code stands as a summary of all stages in the processing.

Similarly, a return code does not represent all repeats of a process. For example, a repeated call to DBCHCL for the Fetch function may generate many return codes of zero and later generate a non-zero return code if the application program continues to ask for the next parcel in the response after consuming the final parcel.
