SQL PRINT vs SQL EXEC












0















When executing the query below if i use PRINT it prints correctly i can copy and paste the printed code and execute it. However is i use EXEC i get the following



error on exec



Is there a way of simplifying what i am doing? Why does SQL PRINT and SQL EXEC deliver these two very different result sets?
