I can't speak for MySQL, but in MSSQL, every query (not just prepared statements) is processed into a Query Plan before processing. The server then caches as many of these QPs as possible, so that repeated calls to the same 'query definition' do not have the overhead of having to re-generate the QP; they just execute in the pre-defined 'most efficient way'. The difference in performance is, therefore, likely to be greater the more complex the query is.
Whether the same holds true for MySQL, I have no idea. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| 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:321699 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4
