Re: [JDBC] Prepare Statement

Nope, I think you are right. The improvement of performance will be
minimal. Because that to parse "SELECT * FROM myfunction(?,?,?)" is very
very quick.
However, I am still thinking if I call one SELECT and one DELECT and one
UPDATE and one INSERT a thousand times against same table with different
arguments, should I consider performance iusse?

Secondly, I assume the function should be a pre-compiled object stored
on server side, doesn't it.

Thanks.

I suppose, but I'm going to put it pretty close to the bottom of my todo

list because it still works even though it doesn't use a server prepared

statement, and as I mentioned earlier the performance improvement if any

will be minimal.  Have you done any testing to show that you are even
getting a performance gain?
