Yes, it's not a bad practice in those situations. One thing to note is that in order to keep the results consistent across recordset pages, add an ORDER BY clause that orders by the same column used in the TOP clause.

I haven't done any analysis into the SQL performance of using TOP, but I'd guess it would be better than CF holding all 40,000 rows and only using a small number of them? -----Original Message----- From: Aidan Whitehall [mailto:[EMAIL PROTECTED] Sent: 15 August 2003 10:39 To: [EMAIL PROTECTED] Subject: RE: [ cf-dev ] <cfquery maxrows="x"> question > With the maxrows="x" argument of cfquery, does the number of retruned > rows get limited when the query goes ahead AFAICT, it's just an output restriction. Doing a select *, adding maxrows="10" and viewing the SQL submitted to the database in Oracle Enterprise Manager certainly makes it look this way. -- Aidan Whitehall <mailto:[EMAIL PROTECTED]> Macromedia ColdFusion Developer Fairbanks Environmental Ltd +44 (0)1695 51775 Queen's Awards Winner 2003 <http://www.fairbanks.co.uk/go/awards> ________________________________________________________________________ This e-mail has been scanned for all viruses by Star Internet.
