I wrote a query to avoid the last record, but i am still getting the last record. (ALL I NEED IS DISTINCT EMAILS)

SELECT DISTINCT CandEmail,CandName,EmployerId,ContNum,IsDeleted,CandPortalId FROM tbl1
WHERE EmployerId = 7 AND IsDeleted = 0

The above query still retrieves the same 7 records with last duplicate email record.

Answer 1

If you do not care which ContNum you get, then you can place an aggregate function around that field and then GROUP BY the rest:

SELECT CandEmail,
  CandName,
  EmployerId,
  MIN(ContNum) ContNum,  -- or you can use MAX()
  IsDeleted,
  CandPortalId 
FROM tbl1
WHERE EmployerId = 7 
  AND IsDeleted = 0
GROUP BY CandEmail,
  CandName,
  EmployerId, 
  IsDeleted,
  CandPortalId 

Or as others have pointed out, you should use aggregate functions on the other fields as well, unless you know for sure there are not different values in those columns:

SELECT CandEmail,
  min(CandName) CandName,
  min(EmployerId) EmployerId,
  MIN(ContNum) ContNum,  -- or you can use MAX()
  min(IsDeleted) IsDeleted,
  min(CandPortalId) CandPortalId
FROM tbl1
WHERE EmployerId = 7 
  AND IsDeleted = 0
GROUP BY CandEmail
