Couple of Useful Queries - Identity Insert Without Identity Column & View Schema Definition

 Identity Insert Without Identity Column

Problem Statement -  There is a source table and a target table. The structure is almost similar.
The ask is to insert data from the source table to the target table.
The target table has an additional column of int type which could be used as a row identifier, however, it's not configured to have auto identity insert and you cannot redefine/recreate the target table.

Solution - Used Row_Number window function by partitioning it with a constant value. Please see below




















Let me know if you guys can think of some other way!


Fetch the schema details of a view

Got a rarer requirement to list out the columns returned from a view along with its data type. 
Here is the query

Issues Integrating Azure Data Factory with GITHUB | IN spite of admin rights on repository

-

Although I have been aware of GitHub for quite a while but got a chance to use it as a repository in the project for storing artifacts only over the past few months.  We use GitHub as the sole cloud repo for storing SQL, Databricks, and Azure Data Factory artifacts.  Got an opportunity to set up GitHub with ADF right from scratch and all the excitement to learn more about GitHub took a back seat when I stumbled upon the following issue Problem Statement - You are an admin on a repo in GitHub and even then get a permission error while linking the ADF to GitHub Solution - After scratching my hairs and going on a searching spree on google for some days, I was able to figure out what needed to be done, however was not aware of how to implement it. Finally thanks to Microsoft for getting on a call and helping me resolve this issue. What needed to be done - Need to authorize AzureDataFactory service so that Github can communicate with it.  How it should be done -  Basically, you need to auth

SQL QUERY NIGHTMARE

Last week, we faced a basic and yet the only major problem that sql developers/admin had to deal with and yes your guess is right, It was with SQL QUERY RUNNING SLOW.  I will be explaining the problem below, however I want everyone reading this to help me find answers because I still haven't found one! One more amazing aspect of the issue was that it worked fairly quickly in Development but was running like a tortoise in Production even though the number of records were practically the same. I'll start by throwing some light on to the execution plan, so that we narrow down to the code which was the culprit here. The code is enclosed into a stored proc. On contacting my dba to enquire about the issue, I got the following replay:- I must hand it to our dba to provide such a detailed response.  So my job was now to look at the code and modify it. What I did was to shrink the calender table into a temp table consisting of few rows that would speed up the operation. Bel

Handling decimal and non numeric types using Case statement

Hi Guys Just encountered a scenario where I needed to handle numeric and non numeric types using Case statement. Here is the synopsis of challenge and solution:- Challenge :- You have a varchar column in your input table having values such as 1.1111, 34, John. CREATE TABLE #TEST ([UpdatedValue] VARCHAR(100)) INSERT INTO  #TEST VALUES('1.1111'),('34'),('John') select * from #TEST Requirement :- You need to round off the decimal values to 2 places  Solution :- I got to know while implementing that for a case statement to work the output data i.e. the resultant data from each case should be of same type. It won't be able to treat numeric and non numerics together. That is why I personally found it a bit tricky but on brain storming solution looked to be very simple. The basic idea is to use different select queries and then union together. Here it is :- select CASE WHEN CHARINDEX('.',[UpdatedValue],0) >=1 THEN CAST( C
