At any point during the Query definition process, the Query can be executed to see the effect by invoking the “Preview” button. If the result set has not been previously displayed, a new Result View will appear after the query has executed. Also, any variables that could be evaluated are updated on the Variables tab. You may invoke the “Preview” button again to update the result set after making changes to your query.
You may save the Query when it is completed, or at any intermediate point, by selecting the “Save” button.
Doing so overwrites any previous content of the Query (without warning).
If you attempt to select another Query in “System Navigation” with unsaved changes to a previous Query form, you will be prompted to save or discard the changes to the previous Query.
