Part of my scripts collection, is a script that returns the details of a table: storage, metadata (sys.objects), partitioning, etc. I was using this script for quite a while and ran ok. Few days ago, however, after I disabled an index on a partitioned table it failed and the error was a bit puzzling: Msg … Continue reading The joy of FILEGROUP_NAME (and probably other as well)
Aggregation and partitioned tables
One of my main tasks is to keep a close eye on performance. Every time we have a major release, I have to start looking at performance, find main culprits and fix them. Well, not me, but work with developers and find a solution to the issues at hand. And our databases are rather large, … Continue reading Aggregation and partitioned tables
Corruption she (the DBCC) wrote….
I received recently an email from a friend asking for my help as he faced a problem.

Of course, I asked what was the problem about and he said: … Continue reading Corruption she (the DBCC) wrote….
DATETIME and its surprises
Well, it's about time I write another blog post (with a promise that I'll do it more than once a year). I'm going to start a series of "bad habits to kick" as for me it is important that we all have a common ground on SQL Programming. 1.

Create certificate from backup fails on SQL Server 2008

When I ran the script (yes, CREATE CERTIFICATE … FROM FILE […]), I … Continue reading Create certificate from backup fails on SQL Server 2008
Say What? – “Management Studio: must be set in single thread apartment (STA) mode before OLE calls can be made”
Yes, I have another couple of minutes to document this weird message. I was trying to access the database properties for one of our databases. Guess what: I couldn't as there was no owner! Well, the easiest thing to do is to alter the authorization on the database; as you may have guessed it already, … Continue reading Say What? – “Management Studio: must be set in single thread apartment (STA) mode before OLE calls can be made”

Move cluster group from one node to another
First off, apologies to the 3 readers I have (I don't read my blog post, I just write), since all of them are far better than I am when it comes to clustering. To cut it short: how can you move ANY resource from one node to another? Namely, the disk witness in the quorum … Continue reading Move cluster group from one node to another
Create SQL Server aliases using registry editor
Another quick one today: how do I create an alias using the registry editor? If you want to want to ask me why would you do such a thing, it means you're reading the wrong blogJ. To cut it short, here are the entries in the registry: [HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\MSSQLServer\Client\ConnectTo] – this is for x64 machines who … Continue reading Create SQL Server aliases using registry editor
