LNNVL function

Anyone got any ideas.

SELECT 1 FROM DUAL
WHERE LNNVL(1=2) returns

1

Suggesting that LNNVL(1=2) evaluates to true

But LNNVL(1=1) evaluates to false

I assume there must be some NULL processing going on too because of the function name.

It seems totally undocumented and there's only one unhelpful mention on Metalink.

Anyone know for sure what it does? Received on Thu Oct 30 2003 - 11:23:27 CST
