Need suggestion on TSql Query with Joins

Hi All,

Please suggest me is there any performance/other differences between the below two queries.

-query1

select T1.name,T1.Number, T2.Dept, T2.Desig

From T1 Inner Join T2 on T1.EID = T2.EID

-query2

select T1.name,T1.Number, T2.Dept, T2.Desig

From T1 Inner Join (Select Dept, Desig From T2) As T2 on T1.EID = T2.EID

Thanks

There is no performance difference for your quires.

Both are executed in same way..

Suppose, if your query2, subquery has any distinct or group by clause then the query1 may perform better than query2.
