Question : SQL Case

I have the following query, but i need to change it a little so that i have a case statement inserted.


SELECT
      TblCustomer.TelNo1,
      COUNT( TblCustomer.TelNo1) AS countDups
FROM        


WHERE    
      (TblCustomerLog.CurrentCustomer = 1)
GROUP BY TelNo1
HAVING COUNT(TblCustomer.TelNo1)> 1

) AS a ON a.TelNo1 = TblCustomer.TelNo1


--      TblCustomer.TelNo1
--      (CASE
--            WHEN COUNT (TblCustomer.TelNo1) > 1
--            THEN 'Duplicate'
--            ELSE 'Unique'
--      END) AS countDups,

Answer : SQL Case

your code so far is a bit reduced, so it's not obvious to see where the subquery/join is happening

this must be removed, to get those with COUNT() = 1
HAVING COUNT(TblCustomer.TelNo1)> 1
