Performance of using a Select For Update vs a correlated subquery

124324Dec 5 2001

I was wondering wether or not it is more effecient to use the
Select ... For Update (with a cursor etc.) versus a correlated
subquery.

I can accomplish the same thing with either however performance
at our site is an issue.
