Hi, i am having a doubt considering what is a proper oracle expression.
In the select referene, there is a number of times where the expr statemnt appears.
I am trying to figure out what an expr is: is it simply a sequence of Varibles, Constants, function and Operators that are evaluated to a result.
Or can you include more sophisticated things like If statemnets?
For Example in the "Description of the illustration
you have got a vector index being assigned an Expression. Could this expression include if statements?
If so... i don't seem to be able to execute it with them.
Thanks in advance. Received on Wed Oct 22 2008 - 09:31:05 CDT
