Defining a Parameter

You can define a parameter in a number of different ways:

in the SQL window use Parameters > View/Edit Parameter to add or edit a parameter
in the SQL window, use the Parms tab on the listboxes to view and edit parameters.
use the queryparm command to query the user for the value of a parameter
use the setparm command to set a parameter to a particular value

The Add Parameter dialog makes it easy to add a queryparm or setparm command to your query. When you add one of these commands, it will be placed at the top of your SQL at the end of the existing query queryparm / setparm commands.

Parameters Dialog

You open this with (from the SQL window) Parameters > View/Edit Parameter

The SQL window has a tab which allows you to view and alter parameter values.
