شكرا خي سعود لاكن ظهرة لي مشكلة Incorrect syntax near

كود :

 Dim con As SqlClient.SqlConnection 'DISTINCT
       '
       Dim strsq2 As String = "SELECT SUM(T3) FROM (SELECT T1, T3 FROM Table1 GROUP BY T1) "
       con = New SqlClient.SqlConnection(constring)
       Dim ds2 As New DataSet
       Adp2 = New SqlClient.SqlDataAdapter(strsq2, con)
       ds2.Clear()
       نص الخطأ Adp2.Fill(ds2) Incorrect syntax near
