Hello , I am unable to work with SQL transformation at least. Where do i need to give connection for sql transformaton ? At session level there is no property . I have created a SQL Transformation and chosen query mode. But do i need to pass connection information to it ? I don't know where do i need to write a query ? I have written a query in file and that file path i gave in the properties of SQL Transformation. But it is not working. Could any one of you please let know how can i work with SQL Transformation? Advance Thanks.
