While I was writing my last blog post about the new SQL SERVER 2012 CHOOSE statement, it also came to my notice that we additionally have the IIF statement.
Again, this was added in 2012.
I’d assume that most people would be familiar with this… Read more
I love coming across features of SQL that I’ve not used before and one happened today – the CHOOSE statement – introduced in SQL SERVER 2012.
So what does it do?
Well basically a label can be applied at a specific index in a list.
Here’s a demonstration script… Read more
Well, it’s the first TSQL-Tuesday of 2014 and one of my New Years resolutions for 2014 is to contribute to each TSQL-Tuesday of the year – lets see how we go!
Well, the subject of this months TSQL-Tuesday is Automation – which is quite obviously something that any… Read more
I remember a fair few years ago when I was relativly new to TSQL creating a stored procedure that used several temporary tables and had faily complex logic.
Occasionally during development the stored procedure would fail with errors – aside from the fact that the stored procedure… Read more
Just a quick post on a seemingly trivial matter that others may find useful.
The post was prompted by the Simple-Talk article on SQL SERVER 2012 keyboard shortcuts
Anyway, I installed SQL SERVER 2012 sometime ago on my laptop and ever since the CTRL-R keyboard shortcut key has… Read more
Well, these are exciting times for the Christchurch SQL SERVER User Group.
After a period of fragmentation where our meetings seemed to be at random intervals – mainly due to certain major events outside our control – such as earthquakes, the city… Read more
As part of any SQL SERVER install that I do, I turn on Remote admin connections (using sp_configure) and open the relevant firewall port – normally 1433 for a default instance – Although this can be altered
As we know, you can open a dedicated administrated connection using… Read more
Did you know that you can actually combine multiple SET operations into a single ALTER DATABASE statement.
It’s true, you can!
Mostly I never see this done.
Maybe it doesn’t make sense! maybe it’s just more readable if a single ALTER DATABASE statement contains a single SET operation!… Read more
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
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
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
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
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,

On Saturday 16th April 2012, I attended SQL Saturday #136 in Wellington, New Zealand.
On Saturday 14th April I’ll be speaking at SQL Saturday 136 in Wellington, New Zealand.
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
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
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
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
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
