Hi,
I need to change the name of the constraint.,
Or i need to drop the constraint, and i need to create constraint
with new
name, how the impact of this in performance, because these constraint
changes am going to do in a table which has 10 million records....
That's how I would do it, create the new constriaint, then drop the
old one.
I'n not aware of any syntax that would allow to rename a constraint.
Cheers,
tom
