ServerProperty(‘Servername’) and @@serverName don’t match


Few days back I was on a fairly secured environment doing my merry work for the consulting company I work for when I realized the serverproperty(‘servername’) and @@servername were not the same.

To be precise ServerProperty(‘Servername’) had the current server name and @@servername was empty.
When the Sys.servers DMV was queried it had the current server name but the server_id was greater than zero.

After speaking to the infrastructure team it was gathered they had renamed a virtual server and installed SQL on it without considering the repercussions.

Now to sort the problem

-    Execute sp_droppserver
-    Executed sp_addserver with the new name
-    Restarted SQL 

I have not taken time to research what other subsystems will have an impact with the way the sever was setup, but for the moment my immediate problem was sorted.

    Also to note: if there is a link server with the same name that too has to be dropped before the default sql instance name is added

How To Execute A SQL Job Remotely

One of the clients needed its users to remotely execute a SQL job and as usual I picked this up hoping for a quick brownie point. Sure enough there was a catch and there was something to learn. Executing the job through SQLCMD was a no-brainer but getting it to execute on the remote machine was bit of challenge. On the coding Front 1    1.)     The bat file included the following code                 SQLCMD -S "[ServerName] " -E -Q "EXEC MSDB.dbo.sp_start_job @Job_Name = ' '[JobName]" 2    2.)     The Individual users were given minimum permissions  to execute the SQL job Ex. use msdb EXECUTE sp_addrolemember @rolename = 'SQLAgentOperatorRole', @membername = ' Domain\UserLogin ' At the client machine              This took a fair bit of time till our sysadmin got me an empty VM machine....

Create a dacpac To Compare Schema Differences

It's been some time since i added anything to the blog and a lot has happened in the last few months. I have run into many number of challenging stuff at Xero and spread my self to learn new things. As a start i want to share a situation where I used a dacpac to compare the differences of a database schema's. - This involves of creating the two dacpacs for the different databases - Comparing the two dacpacs and generating a report to know the exact differences - Generate a script that would have all the changes How to generate a dacbpac The easiest way to create a dacpac for a database is through management studio ( right click on the databae --> task --> Extract data-tier-application). This will work under most cases but will error out when the database has difffrent settings. ie. if CDC is enabled To work around this blocker, you need to use command line to send the extra parameters. Bellow is the command used to generate the dacpac. "%ProgramFiles...

High Watermarks For Incremental Models in dbt

The last few months it’s all been dbt. Dbt is a transform and load tool which is provided by fishtown analytics. For those that have created incremental models in dbt would have found the simplicity and easiness of how it drives the workload. Depending on the target datastore, the incremental model workload implementation changes. But all that said, the question is, should the incremental model use high-watermark as part of the implementation. How incremental models work behind the scenes is the best place to start this investigation. And when it’s not obvious, the next best place is to investigate the log after an test incremental model execution and find the implementation. Following are the internal steps followed for a datastore that does not support the merge statements. This was observed in the dbt log. - As the first step, It will copy all the data to a temp table generated from the incremental execution. - It will then delete all the data from the base table th...
