Subj:   Re: Derived Tables and depth of nesting
 
From:   Barbara George

Jeremy

Thanks for the prompt and detailed response.

Running the SQL for tables A & B individually (copying the exact code from the main statement), each gives 1 row.

Running the complete SQL for table 5, with the derived tables, also gives one row.

To test the main SQL I took out the functions and the group by, and twice the number of rows were returned. (Tested by leaving table5 out of the main SQL)

I do agree that creating the temporary table would have eliminated duplicates.

Barbara
