A bit off of this particular topic but this got me working with JavaCast( ) trying to influence the way CF handles the comparison operater. I wrote a blog post about it.

That's fair enough, and I do appreciate the critique. I do however feel that I've shown an iterative test to be a very good assessment for the specific bit of code that prompted my original post. If it helps, I did run the test originally for 10,000 iterations which, given my application, is a very realistic number to consider. While the comparison is less dramatic the cfswitch is still a full second slower which is significant enough to me not to use it in this specific situation. (47 ms / 1141 ms) My CIO has requested that the average page load time in our app be 3 seconds or less. Now I am being told to burn 1/3 of that time purely because a switch is more readable and it would be "dumb" to use a conditional structure known to be faster in CF7. Personally I think that advice stinks. :) > I would recommend that you investigate doing that conditional processing > > in a stored procedure if you can. I was waiting for that. :) What I am working on happens to be the interface for a generic reporting tool where we define dynamic criteria and write custom SQL in a proc for each report. It's very handy because only the SQL required to produce the results is all that's necessary to build a new report. The CF code in question displays results in a dynamic way formatting each value and aligning it with appropriate HTML etc as necessary based on the meta data available from the result set and the column types. I am always open to suggestions, but I would hard hardly call it the job of my SQL server to apply formatting and HTML to my data for obvious reasons-- the largest of which would be separation of data layer from display layer. Of course I could write an intermediate and generic proc which would format the result set before handing it to ColdFusion, but that would take more obfuscated dynamic SQL than I care to deal with. I would only resort to another language if what I wanted could not be accomplished quickly and easily in ColdFusion 7, and in this case it can-- with the cfif tag. :) ~Brad ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Enterprise web applications, build robust, secure scalable apps today - Try it now ColdFusion Today ColdFusion 8 beta - Build next generation apps Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:293826 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4
