1       10       Tent 
2       10       Truck 
3       20       Tent  
4       20       Tent  
5       20       Truck

Result:

ID     ORDID    ITEM

6       30      Tent  
7       30      Tent

Answer 1

Try this:

SELECT ID, ORDID, ITEM
FROM YourTable
WHERE ITEM = 'Tent'
  AND ORDID NOT IN (SELECT DISTINCT ORDID 
                    FROM YourTable
                    WHERE ITEM <> 'Tent')
