I had a file (historical FTSE values) to load into a database for some development work so I started up the SSIS Import and Export Wizard to bring it in. There was no error but after three or four attempts it was still failing to bring any rows in. Although I’ve done a lot of ETL I’ve generally used utilities or import exes, so this seemed like a opportunity to get my head around BULK INSERT and bcp.

Sequential uniqueidentifiers in Sql Server Tables
I’ve just come across this feature of Sql Server which apparently has been around since Sql 2008 (code in this example tested in Sql Server 2014).

It would be useful to be able to switch on logging of executions for a period of time (prior to an upgrade of the database for example) so that obsolete code can be removed and problems pre-empted.

SQL Tricks for Tricky Logic (2)
I’ve been working with Linq in .NET lately and there have been a few posts I would have liked to add but since I said I was going to blog SQL tricks I’m putting other topics to one side for the moment.
So… another situation where it would be useful to have an SQL trick is the case of the filtered outer join. Continue reading SQL Tricks for Tricky Logic (2)
Enforcing the Table Type Returned by a Sql Function
I’d like to enforce the user-defined table type returned by a sql function, making the following code possible (I haven’t of course defined the function so it won’t execute): Continue reading Enforcing the Table Type Returned by a Sql Function
CLR Stored Procedures in SQL Server 2008
I recently got around to setting up Integrated CLR in my SQL Server 2008 installation, and coding a couple of stored procedures. These notes reflect my first look and a minor “gotcha” to be aware of. Continue reading CLR Stored Procedures in SQL Server 2008
