When is it necessary to use a table variable, a temp table and a derived table in a stored procedure? Does it depend on the total number of records. Lets say the Stored Procedure1 returned 10,000;
Stored Procedure2 returned 100,000 and stored procedure3 returned 1,000,000,000 rows.
When creating the stored procedures above when should on implement TABLE variable, TEMP tables with an index and DERIVED table.
