Teradata QS accepts single- or multiple-statement query requests for execution at a later time. However, scheduling a request does not guarantee that it is executed at the date and time specified. Scheduled requests are subject to the same Teradata Database rule checking as are interactive requests.

In addition, an execution time frame must be available during the time specified to execute the request. To learn more about execution time frames, see “Configure Execution Time Frames” on page 38.

Scheduled requests are subject to three phases of processing:

  • Request Checking
  • Job Dispatching
  • Job Execution
