Here's a quick one for you, have you ever spent all day working on some query or another only for SSMS to crash or for you to accidentally close the tab that you're working on without saving the query? I'm sure you have, we all have. What happens next is usually a muttering of some... Continue Reading →
This month's T-SQL Tuesday invitation comes from Kevin Chant and he's asking us about a fantasy feature that we'd love to see in SQL Server. I had a little think about this and there's one thing that came straight to my mind, it is something that's possible with third party tools but isn't something supported... Continue Reading →
This is going to be a quick post but this morning I was asked the question, 'how can I get the name of all the database snapshots on a SQL Server?'. It was an interesting question so I thought I'd share a quick script to do just that. We're going to need to tap into... Continue Reading →
Intent locks, one of those things in SQL Server that seem to be very often misunderstood. They're something that I've found myself explaining time and time again, I've even been on calls with customer DBAs who don't fully understand why they're there and what they're doing. So what exactly is an intent lock and why... Continue Reading →
I recently hit this rather interesting issue when migrating a bunch of SQL Servers onto a nice, shiny new SAN. The plan was simple enough, take the secondary servers in the four node cluster, migrate those over to the new SAN provided to me by the lovely storage guys. Once they were done, fail the...

Firstly, I'd love to see the total size of the drive and possibly even a percentage of free... Continue Reading →

Here's a little error that I stumbled across the other day when trying to migrate the data files of an Availability Group secondary node onto a nice new SAN. I started off by running the following command against the secondary server. ALTER DATABASE SQLUndercover MODIFY FILE (NAME = 'AG01', FILENAME = 'E:\DATA\AG01.mdf') There's nothing wrong...

You know what it's like, you need to fail your AG over but is it safe to fail over? Perhaps you've clicked on 'failover' for the AG and there's a little green tick and no data loss reported... Or maybe you've checked out sys.dm_hadr_database_replica_cluster_states and 'is_failover_ready' is reporting a 1. So, you're cool to failover,... Continue Reading →
