Matthew, SQL should have no problem with a null being passed for a list, even with integers (I just tested this against MS SQL Server 2005, although I use BlueDragon JX 7.1 instead of ACF).
If you are using the null="#!isDefined('myVar')#" attribute in your cfqueryparam, then a SQL NULL should be passed if myVar is undefined. However, you might want to change that to null="#!isDefined('myVar') OR !ListLen('myVar')#" which will also send a null if myVar is defined but empty. Then you can change the value attribute to value="#myVar#" HTH, Carl > Hey Ric, let me just add a little bit of what I've experienced in the > cfqueryparam list.
