So I have a shiny new laptop (Lenovo Thinkpad T61p) that I have been configuring for the last 2 weeks now. I have installed all the office applications and most of my development tools. ColdFusion 8.0.1, Eclipse 3.4, FlexBuilder, CS4 and MS SQL Server Express 2008. verything worked reasonably well. Except that I had to update the JDBC drivers from Microsoft to version 2 CTP, and then I had to switch to the JDBC 4 drivers because the other driver is supposedly incompatible with an 1.6 JVM. (It worked just fine with the 1.x versions of the drivers.)

And that is where the trouble started, many queries suddenly gave datatype resolution errors in ColdFusion. After some testing it turned out that problem queries are typically similar to:

?View Code SQL
	SELECT
		T.credits
		, PT.pageText AS displayName
	FROM
		test
			INNER JOIN
		pageText PT ON T.nameTextID = PT.pageTextID

In a subsequent QoQ there would be an error if the datatype of PT.pageText was an N-datatype. What fixes the problem is to change the datatype using an explicit cast:

?View Code SQL
	SELECT
		T.credits
		, CAST(PT.pageText AS VARCHAR) AS displayName
	FROM
		test
			INNER JOIN
		pageText PT ON T.nameTextID = PT.pageTextID

Not something that I fancy changing in all queries, but since this version of the driver is still a technology preview not something that really bothers me either.

Next on the list of applications to install was LiveCycle ES. Installation was a bit troublesome, the installer doesn’t recognize Flash 10, the LC Designer from LC ES is incompatible with the LC Designer from CS4 and the configuration instructions haven’t been updated for CS4 yet, but in the end I got it all installed. But not running. LC Designer crashed consistently within 3 seconds of being started. After lots of digging and searching I finally stumbled upon an explanation of the problem.

SQL Server installs a newer version of the MFC DLL on top of the one we install, and the new version has a critical bug.

Other people have reported there are lots of other applications that suddenly start crashing as soon as MS SQL Server 2008 is installed. Or maybe it is not really MS SQL Server 2008 but on of the dependencies, like the .NET Framework 3.5. I don’t know, I don’t care, I think MS SQL Server 2008 has wasted enough of my time and I have uninstalled it completely.
