SSPI error and Incorrect timing.


Recently, quite out of the blue I started seeing this error when I tried to log into my SQL instance using SQL SERVER Management Studio (SSMS)

Now, I could RDP to the server and connect to the local instance using SSMS, however any attempt to connect to the… Read more

Following good practice saves wasted time down the line.


Sometimes I come across what I call unusual coding practices. Developers usually have pressure on them to deliver and this often results in simply delivering code that works – with very little attention to best practice , performance or security.

Sometimes this lack of attention to best practice… Read more

The first record on data page.


I had a recent conversation about data pages. There was some debate about the location of the first record on that page and whether or not it’s location is always after the page header.

As we know the page header is 96 bytes long – so does it… Read more

2012 DDL for Roles


I’m extremely pleased that Microsoft are continuing their commitment to provide full DDL to preform TSQL operations that have previously been preformed using stored procedures.

The particular case that I came across today was regarding roles and the ALTER ROLE syntax.

Prior to SQL SERVER 2012, it has… Read more

Listing SQL Instances on a machine (or list of machines)


Recently I was updating some of my Powershell scripts for managing SQL SERVER instances.

Generally, when writing a Powershell script to do something SQL related, the script takes the form of the following,

Database ownership


One of the features that I most like about management studio is the ability to generate a script of the actions that have been taken in one of the (many) dialog boxes.

This has tremendous value for both learning and for creating scripts to pass to another DBA. Read more

Remote DAC connections


I wrote a post recently about setting the DAC port for an SQL instance.

I now do this as a matter of course on all of my SQL instance as I manage most of them remotly.

However, from time to time I discover instances that have had… Read more

Setting the DAC port….


I had a situation today where I needed to ensure that the dedicated Administrator connection (DAC) ran on a specific port.

The main reason that I wanted it on a specific port was so I could use the connection remotely (if needed) and because the connection was on… Read more

Watch those VARCHAR(MAX) columns, and ONLINE index rebuilds


I’ve noted a few instances lately of cases where VARCHAR(MAX) columns have been used unnecessarily, when a small value (for a VARCHAR) would have been fine.

Apart from the storage implications of a VARCHAR(MAX) column there is also the issue that in SQL SERVER 2008, having a column of… Read more

sp_configure OR sys.configurations? and do you back these up?


I was checking out some of our configuration options today using sys.configurations and I started to wonder how many people actually use this table, or whether most people simply use the more common system stored procedure sp_configure.

As sys.configurations is simply a table, we can use an ORDER BY… Read more

Dropping a database – such a simple thing!


I think it’s a safe bet that everybody here has issued a DROP DATABASE statement and knows what to expect.

Well, today I was experimenting with a development database. The script I was using employed simply reusable code to drop and re-create the database – or so I though. Read more

Online index rebuilds


I’m probably not the only one that has noticed that as the volume of data gets bigger in out databases, the time taken to preform maintenance increases.

This seems to be a simple fact of life for the DBA. But as our maintenance time increases, we need to be… Read more

A second week at SQLskills – performance tuning

Select from a table with no rows returned.


I recently ran into a nice feature that I had never encountered before.

Sometimes, when developing or administrating an unfamiliar table we will simply do a “SELECT *” so that we can quickly see the column names.

This is pretty much fine when the table is small.

However in… Read more

Free SQL Exam cram sessions from Microsoft.

One good way of measuring these skills is to sit certifications and… Read more

A curious case of a missing configuration group.


I recently received a brand new windows 7 virtual machine for my every day work use and one of the first things that I did was install SQL SERVER 2008 developer edition on it.

As I’d expect, this was a pretty straight forward task and before long I had… Read more

Catalog view or compatibility view?


The recommended way to access SQL SERVER metadata is through the catalog views.

The challenge is to be able to distinguish between the catalog views and the compatibility views, because we always want to use the catalog views rather that the compatibility views.

The compatibility views basically… Read more
