In the grid in the Conditions section, select the Unique Records Only check box.
Note: When you are using Oracle schema, if a text field is exists in a query and the Unique Records Only check box is selected when the query is run, an error message will appear. If you are using an Oracle database and want to run a query with a text field, do not select the Unique Records Only check box.
In the content heading, select .
The query is run, and the results will include only unique records.
