Joining Strategy- - response (1) by dnoeth

Hi Nishant,
yes, the Nested Join might need no spool, but it's for joining a single row (or a very small set of data). 
 
There are several subtypes of Nested Joins with differnt plans, you'll find more than you ever want to read about join planning and optimization in the "SQL Request and Transaction Processing" manual :-)
