How To Insert Data To A Timestamp Column


It is mentioned in the SQL world that you can’t insert a value into timestamp/rowversion column. But you actually can, I was surprised to find there was no record of this workaround on the internet. That said, I looked no more than 15-20 minutes. This was tested on "SQL Server Edition : 2012 Enterprise".


The problem with timestamp is that it doesn’t accept an explicit value to a table
Ex.  
Create table #Customer (
ID int ( identity(1,1) ,
Name nvarchar(100),
Address nvarchar(1000),
LastestVersion  timestamp )
Insert into #Customer (Name , Address , LastestVersion)
Select top 500 Name , Address , LastestVersion
From  Actual_Customer
The above will error out complaining that a explicit value can’t be added to the #Customer table due to rowversion.

However if you define the table on the fly with “SELECT INTO”, SQL server is tricked into believing the timestamp column is another jack datatype.
SELECT top 500 Name , Address , LastestVersion
INTO #Customer
FROM  Actual_Customer


I haven't spent a lot of time researching in to how "Select INTO" bypass the default behavior, but my hunch, due to the minimal logging with "Select INTO" there is possibly few operations/validations that are overridden.  


Conclusion.

It’s time to request Microsoft SQL Server provides an override setting that allows data to be inserted to timestamp/rowversion datatype.

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...

The maximum number of working threads (100) are already running

The problem                 This afternoon, out of the blue, the development folks called over wanting to know why the DB server was not responding, sure enough the databases were not accessible from application and from MMS. I knew there weren’t any maintenance happening and so I logged in to the server remotely and found that the sql services were still running as usual and the services had not restarted. To my surprise, in 10-15 mins everyone was able connect to the server again.  My first thoughts were,  it would have been an issue with the network and due to the glitch the servers weren’t accessible during the  time period. Environment details : -           The sql server were on a hyper v with a single CPU and 1024 memory -           There was 80 + transaction replications setup and further 20-30 sql ser...
