What is Stitch Query in Reportnet? | Cognos

Framework Manager generates a separate query for each 'FACT' table and joins the result set. This is called Stitched query. I think when there is no join between two tables and we are dragging in 2 cols from 2 diff
tables which doesn’t have joins then cognos will automatically build 2 or more select clauses with full outer join stitching in the 2 select clauses this is called stitched query
