Hello Gurus, A SQL tuning question. Given three large tables with the same millions of rows, and all three are referenced in a query, without any filter, as under:
Select .............................. from largetableA a, largeTableB b, largeTableC c where a.empnum = b.empnum and a.empnum = c.empnum; What would be the prefered way of joining these tables, Merge Join, Nested Loops or Hash Joins?
