Yes, but in your example, isSuperUser will probably only contain boolean values.
query.recordCount will not contain "typical" boolean values. In the case of query.recordCount, FALSE=[0] and TRUE=[everything else]. I've done it both ways. "query.recordCount gt 0" tends to add a bit more explanation as to the intent of the code. However, it does add a few keystrokes.

Personally, I've always seen the implicit type conversions as a feature of CFML, not a thing to be avoided. As the programmer, if you're certain a variable will contain data that the language can convert with predictable results, then there is no reason not to use it aside from personal preference. Take, for example, pulling a bit value from a database. Let's use isSuperUser as an example in a membership system. Take the following, should it be... <cfif userInfo.isSuperUser> OR <cfif userInfo.isSuperUser is 1> Is ColdFusion seeing that as a boolean because it came from the database as a bit field, or as an integer because the database returned a value of 1 (assuming SQL Server here)? In ColdFusion, it doesn't matter and you will get the same results either way without any fuss. -Justin Scott ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;207172674;29440083;f Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:317674 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4
