Setting the PDQ priority dynamically

You can use the SET PDQPRIORITY statement to set PDQ priority dynamically within an application. The PDQ priority value can be any integer from -1 through 100.

The PDQ priority set with the SET PDQPRIORITY statement supersedes the PDQPRIORITY environment variable.

The DEFAULT tag for the SET PDQPRIORITY statement allows an application to revert to the value for PDQ priority as set by the environment variable, if any. For more information about the SET PDQPRIORITY statement, see the IBM® Informix Guide to SQL: Syntax.
