See limk :- https://technet.microsoft.com/en-us/library/bb522522(v=sql.105).aspx -- MERGE statement with the join conditions specified correctly. USE tempdb; GO BEGIN TRAN; MERGE Target AS T USING Source AS S ON (T.EmployeeID = S.EmployeeID) WHEN NOT MATCHED BY TARGET AND S.EmployeeName LIKE 'S%' THEN INSERT(EmployeeID EmployeeName) VALUES(S.EmployeeID S.EmployeeName) WHEN MATCHED THEN UPDATE SET T.EmployeeName = S.EmployeeName WHEN NOT MATCHED BY SOURCE AND T.EmployeeName LIKE 'S%' THEN DELETE OUTPUT $action inserted.* deleted.*; ROLLBACK TRAN;

Hi You can use FULL JOIN to compare a common column in two different table. Try this: SELECT * FROM TABLE1 FULL JOIN TABLE2 ON TABLE1.COMMONCOLUMN = TABLE2.COMMONCOLUMN WHERE TABLE1.COMMONCOLUMN IS NULL OR TABLE2.COMMONCOLUMN IS NULL Regards Deepak
