Hi all, I want to find duplicate records from a joint table result (The two tables are from two different DB's). Bellow are the tables and my requirement. Table1 from DB D1 EmpID 205 205 205 206 207 207 208 209 210 211 Table2 from DB D2 PayID 205 206 207 208 209 210 211 i have joined these two tables on the basis of EmpID = PAYID and got the following result SELECT T1.EMPID,T2.PAYID FROM D1.table1 T1 INNERJOIN D2.table2 T2 on T1.EMPID collate Latin1_General_CI_AI =T2.PayID EmpID PayID 205 205 205 205 205 205 206 206 207 207 207 207 208 208 209 209 210 210 211 211 In this result 205 and 207 having duplicate, so i want a query to display the duplicate entries .
Answer:

Just add the following: GROUP BY T1.EMPID,T2.PAYID HAVING COUNT(*) > 1 This will summarize to just the distinct T1/T2 pairs and limit the resultset to only those groups that appeared more than once before summarizing.
