No, not #tables – actual tables. Here’s how: Transact-SQL USE tempdb; GO /* This one is only available during my session: */ CREATE TABLE #myTempTable (ID INT IDENTITY(1,1), Stuffing VARCHAR(100)); GO /* This one is global, meaning it's available to other sessions: */ CREATE TABLE ##myTempTable (ID INT IDENTITY(1,1), Stuffing VARCHAR(100)); GO /* You can…

SQL Server 2005 support ends next week. Here’s my tribute to it.

Last Updated February 13, 2017

I remember the first time I used SQL Server 2005. Did you know SQL Server has an expiration date on the bottom of the box? Also, this one is curdled. I was a database administrator working on a new-build data warehouse project in Miami. Both our data warehouse and SQL Server 2005 were looking like…

Hey, remember 2005? What a great year for… not SQL Server. Mirroring was still a Service Pack away, and there was an issue with spinlock contention on OPT_IDX_STATS or SPL_OPT_IDX_STATS. The KB for it is over here, and it’s pretty explicit that the issue was fixed in 2008, and didn’t carry over to any later…

Presto, the schemabinding option means no one can change the underlying tables. (At least, until they…

A sampling of things overheard at our 2015 Performance Troubleshooting Class in Denver: “I’m not a GUID hater.” “Oh, God help me.

Let’s say you’ve got a vendor application that creates tables, loads them, queries them, and drops them all the time. You can’t change the code. The tables involved desperately need an index in order to go faster, and they’re your biggest performance bottleneck. Enter DDL triggers. Regular DML triggers fire when you insert/update/delete rows in a…

Bad Idea Jeans, Columnstore Indexes, Indexing, SQL Server

SQL Server 2012 introduced nonclustered columnstore indexes, but I never saw them used in the wild simply because once created, they made the underlying table read-only. Not a lot of folks like read-only tables. (Bad news, by the way – that limitation hasn’t disappeared in 2014.) SQL Server 2014 brings clustered columnstore indexes, and they’re…
