Re: Correctly using CFOUTPUT
We discussed this on the list no more than a few weeks ago. While intuitively (at least to me) it would seem that a CFOUTPUT loop would execute faster than a CFLOOP, that simply is not the case. I think we pretty much reached the concensus that while CFLOOP is faster, the difference was so small that it was not worthy of making a fuss over.

RE: Correctly using CFOUTPUT
Never is too strong a word. If you have a CFOUTPUT at the top of the page and another CFOUTPUT at the bottom of the page, it's not better to enclose the entire page in one CFOUTPUT tag as you're suggesting. Extraneous code, no. Extra code, yes - if it improves performance, reliability, or readibility.

Re: Correctly using CFOUTPUT
I've always been curious about that. I saw Ben Forta speak once about that issue, and have seen that here is well. Is it just that the looping PCode is just a lot more cumbersome because Allaire grouped so many different kind of looping controls in one tag? I don't get it, loops are usually low overhead in other programming languages. Hmm.. Maybe query based loops is where the problem lies. They might have to do a lot of conversion between a clean loop and a query resolution that adds the overhead. -Bill www.brainbox.tv - Original Message - From: Bill Killillay [EMAIL PROTECTED] To: CF-Talk [EMAIL PROTECTED] Sent: Thursday, May 31, 2001 4:35 PM Subject: RE: Correctly using CFOUTPUT Since when is CFLOOP faster then CFOUTPUT?

RE: Correctly using CFOUTPUT
I personally have a tendency to use Listing 1's format more often than I use the one in Listing 2. The only difference is that I put in my table tags BEFORE my CFOUTPUT tags, that way if I'm looping through a query's results, I don't have a new table being created for each record. :) Scott Wolf Goodfriend Computer Training -Original Message- From: J Winter [mailto:[EMAIL PROTECTED]] Sent: Tuesday, May 29, 2001 9:48 AM To: CF-Talk Subject: Correctly using CFOUTPUT Hi, I've always been curious about this.

RE: Correctly using CFOUTPUT
It depends how you want the results to be displayed, but I'd recommend putting the cfoutput tags inside the table before the tr as otherwise you'll open a new table for each line of results, which isn't good if you're pulling rows and rows back from a database.

RE: Correctly using CFOUTPUT
Hi, let's assume that there is no query for the CFOUTPUT tag. Which would be better coding style? I've seen it done both ways: CFOUTPUTing each variable and CFOUTPUTing/encapsulating the entire template. Sometimes when I run into things I think what do the pros do?.
