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...

We love xp_fixeddrives here, it's a quick and simple way to see how much space you've got available on your drives. But there are just a couple of things that I really wish it would do better. Firstly, I'd love to see the total size of the drive and possibly even a percentage of free... Continue Reading →

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 →
It wasn't until the other day that I realised what the behaviour was when rolling back a transaction with an insert on a table with an identity column, to be fair I have never had a need to do so but I know that there are people who like to run code like below to... Continue Reading →

This month's TSQL Tuesday comes from Shane O'Neil and he's asking us to 'dip into the cookie jar' (or raid the biscuit tin, for us Brits 😉 ), essentially how we use past accomplishments to help us through difficult or challenging times. I've been trying to think about this and while like everyone I've had... Continue Reading →
A while back, I was having a conversation about a deadlocking issue and suggested that an index could perhaps help solve it. The reaction I got was along the lines of, 'What, how can in index solve a deadlocking issue?' So, can we solve a deadlocking issue with an index? Let's create a rather simple,... Continue Reading →
