Query Builder Defaults
Use the Query Builder Defaults tab to select only distinct records.
Distinct records are records that are not the same or are not duplicate records.
Note: The Query Builder supports many features. The tabs you
                           		  see depend on the feature you are using. 
                           		
 
                        		
                        To set query defaults:
- Open Query Builder.
 - Click the Defaults tab.
 - To eliminate duplicate records, select Return Distinct Rows Only.
