We're trying to solve a bottleneck in one of our web-applications that was introduced when we started allowing users to generate reports on-demand. Our infrastructure is as follows: 1 server acting as a Webserver/DBServer (ColdFusion 7 and MSSQL 2005) It's serving a web-appl...
Deploying a WCF Service
I will be deploying my first WCF service in the next few days on a Test server (MS Server 2003 O/S). This particular service will do nothing more than run some queries against a SQL Server 2005 (most likely on the same box) and return the values to the caller. My question is, unlike the "classic" web services, with WCF I now have cho...

Why is it so difficult to do a loop in T-SQL
OK, I know it can be done, I do it quite often, but why so difficult to do a loop in T-SQL? I can think of a ton of reasons I'd want to parse thru a query result set and do something that simply can't be done without a loop, yet the code to setup and execute my loop is > 20 lines. I'm sure others have a similar opinions so why are we st...

Optimizing a Query to Build Averages
Hello All, I recently built a query in SQL that I can use to look at our payment log and find out an average number of payments made per hour over a period of time.

Delphi 2007 Pro - Best way to connect to SQL Server
I usually use Delphi-targeted databases for most of my work (NexusDB typically, lately), but still have bad memories of how painfully slow connecting (and posting) to MS Access was via ADO.
