require.select command

The require.select command is used with any AQL sentence when you want to process a select list.

The require.select AQL connective ensures that a select list is present before running the TCL command.

Syntax

list filename require.select

Parameter(s)

file.name Name of the file containing the select list you are processing.

Description

The require.select command requires an active select list to run the process. If a select list is not active, you will see a message similar to the following:
No active list found, processing terminated.
If you see the previous message, use one of the following commands to make the select list active, and then repeat the AQL sentence:
  • form-list command
  • get-list command
  • select command
  • sselect command
  • qselect command
