Who’s been logging into my SQL Server?

ERRORLOG, LOGIN, Security, SecurityFightClub, SQL Server 2000, SQL Server 2005, SQL Server 2008

Knowing who has been logging into your SQL Server is one of the key things to know about your SQL Server.  It lets you know quite a bit about who’s using your server, and about who’s been trying to break into your SQL Server, and most importantly if they have succeeded. Obviously you can...

Clean up the backup history



Posted by: Denny Cherry
Backup & recovery, Database Administration, sp_delete_backuphistory

Something that most people don't release needs a little TLC in SQL Server is the backup history. Every time a database is backed up records are written about it.  Over time this can add up to a lot of useless data floating around the SQL Server in the msdb database. If you like to use the UI...

Outside Queue to SSB adapter

MSMQ, Open Source, Outside Queue to SSB Adapter, Service Broker

Something that I think that Microsoft should include with the SQL Service Broker is an adapter so that MSMQ messages (and other messaging systems as well) will flow automatically into the SQL Service Broker.  Since Microsoft hasn't gotten around to writing one I'm going to start. It shouldn't...

How do I change from push to pull subscriptions in SQL Replication?



Posted by: Denny Cherry
distrib.exe, Replication, SQL Server 2000, SQL Server 2005, SQL Server 2008

The official answer is to delete the subscriber and recreate it pushing a new snapshot to the subscriber. The much quicker and easier method is as follows. 1. Stop the distribution agent on the machine that it's currently running on. 2. Disable the SQL Agent job that runs the distribution...

Pull vs. Push Subscriptions? Which one should you use?



Posted by: Denny Cherry
Replication, SQL Server 2000, SQL Server 2005, SQL Server 2008

This is a "it depends" sort of question. These are my recommendations, your mileage may vary. Your distributor is on the same system as your publisher - Pull is probably for you Your Subscribers are a very high transaction count - Push is probably for you You need to manually copy the...

How can I remove duplicate records in my tables?

CTE, DELETE statement, SQL Server 2005, SQL Server 2008, T/SQL

All to often we end up with duplicate rows in a table.  The best way to keep duplicate rows out of the database is to not let them in.  But assume that they are there.  This bit of sample code shows how to delete those duplicate rows quickly and easily in a single statement.  No temp tables...

Should I install an Anti-Virus software on my server?



Posted by: Denny Cherry
Anti-Virus, SQL Server

Yes, for crying out loud yes. Every server that can access the Internet or be access from the Internet, or that can be accessed from a computer that can access the Internet should have an anti-virus on it.  Preferably a corporate wide solution like

Why should the DBA care about Network Firewalls?

Networking, Security, SecurityFightClub, SQL Server

All to often I see people online asking some sort of question about connecting to their CoLo'ed SQL Server and they connect directly over the Internet.  This is nuts people.  If you can access your SQL Server via Management Studio from anywhere on the Internet so can people who would love to...
