    Posted on Jul 27, 2009 at 1:46 AM

    that will always happen with the ram based stuff. You can set a higher timeout in the CF administrator, but you should consider ram like the session of application scope, ie not persistant... read more »

    Posted on Jul 19, 2009 at 4:18 AM

    I'd be interested to see how it performs compared to loading the values in a struct and doing a structkeyExists, a very common pattern i use to date I have seen a lot of ugly repeated array searching code in CF over the years...... read more »

  • Learning ColdFusion 9: IsNull() And Working With NULL Values

    Posted on Jul 19, 2009 at 4:10 AM

    Ben, in oracle land a null gets treated like empty string. It's different between databases. Maps quite nicely to CFML. Not having nulls actually reduces the amount of code you have to write. Over on the FDO project something similiar came up and there was a lot of extra null checking handling cod... read more »

  • Random Thought: The Database Bottleneck And Elegance

    Posted on Nov 29, 2008 at 9:05 PM

    One of the most useful things for tuning performance are Materialised Views (oracle speak) which SQL server added in the last release from memory. Basically it lets you make a view into a normal table which is dynamically updated by the database either on the fly, or on demand. You can also create... read more »

  • "Style Bleed" Problem Fixed In POI Utility Tags

    Posted on Oct 6, 2008 at 11:30 AM

    I was banging my head against the wall with a bug I had using the POI lib and upgraded my local version. I seem to remember reading that the image stuff is newer than the ancient CF version. The bug by the way was using the cell aliases but accidently naming the alias with the @ prefix... which mea... read more »

    for people using oracle, there is a good discussion on the pro's and con's about binding or not binding with a static value http://www.oracle.com/technology/oramag/oracle/08-jan/o18asktom.html as for the stored procedures, it's a lot easier to tune a CF application which doesn't use stored proce... read more »

    That's great to know :) the problem with the pseudo html xls files is that excel chokes when the file gets too big the way around that is then to wack your data into a database and then suck it in via odbc into excel, but use '~' or '|' as your new line character and then do a search a replace on ... read more »
