Wait-for-response is a one byte field that specifies whether DBCHCL is to retain control or return control to the application in two situations:

  • When the application has called DBCHCL for some function and DBCHCL cannot send that request to the Teradata Database because another request in the same session is active, DBCHCL is unable to initiate that function.
  • When the application has called DBCHCL for the fetch function and DBCHCL cannot provide access to a parcel or buffer (depending on the setting of Parcel-mode-fetch) because the buffer is being restocked, DBCHCL is unable to complete the fetch function.
