Elementary sub-query or EXISTS clause wouldRadically improve performance.
If you like fancy coding you could pass XML as
parameter and use XQUERY.
You should read the article about the splitter. It will blow the doors off an XML parser. You can find the article by following the link in my signature about splitting strings. The article is great but the ensuing discussion (although incredibly lengthy) is even better.
Be careful now. He's not talking about passing a CSV and using an XML parser to split it. He's talking about passing actual XML and parsing it, which is actually very fast.
Ahh I guess I misread that. :blush:
It is fast on the sql side of things but I have never really been convinced that applications gain much benefit because of all the extra data that has to be passed.
