A change in direction would be to consider if you could construct your queries with CFQUERYPARAM. Then you wouldn't need to worry about quoting or apostrophes. I'm not good off-the-cuff with cfqueryparam. I'm sure someone here can give a good example of a null check added to a cfqueryparam ...

RE: Iif() and StructKeyExist()
I don't think you can use IIF in this case as IIF has a habit of evaluating both results regardless of whether it resolves to true or false. Even if proximity doesn't exist, it will still evaluate values[i][proximity]. Yeah, that's how it's starting to look. Well, thanks for the confirmation.

RE: Iif() and StructKeyExist()
dont have time to test, but would it not need to something like this??? #Iif(not StructKeyExists(values[i], proximity), DE(null), DE(values[i][proximity])))# You would then need to check the value and decide whether quotes would work Could be wrong... my 2 secs worth -Original Message- From: Aidan Whitehall [mailto:[EMAIL PROTECTED]] Sent: 20 February 2003 21:18 To: CF-Talk Subject: Iif() and StructKeyExist() I've got an array of structures and am looping through them and writing several queries on the fly.
