Always check the stored procedures and triggers. For SQL it must follow SDLC with the user's requirements that were communicated to management. No matter what flavor ov Unix box. Sun, Solaris etc. Guys with main frame and mid range experience were easiest to train instead of PC dudes.

Thank you, Please subscribe our channel for regular updates , all the best
But we can use aggregated column in where by using nested query/sub query/cte
You're absolutely right! While aggregate functions can't be directly used in the WHERE clause of most relational databases, you can achieve the desired filtering effect by using a subquery (also called a nested query) or a Common Table Expression (CTE).
thank you..this what i learned from santosh sir@@KSRDatavizon ... (KSR Student)
This video is a gold mine. Thanks you Sir.
Glad it was helpful!

In the first question of sql coding , the 3rd maximum salary person , can we use large ( salary , 3) , to find the 3rd largest salary and then write an outer query to fetch the employee name from this table with the third largest salary ? Would it also be correct ?
Where is this question in this video
👌
thank you, please subscribe our channel,
Also , in the second question , can we use row number () over ( partition by id order by id ) , so that any id that duplicates will have the row no as 2 and the rest will have one , so we can select the records where row number =2 ?
You can simple do
With cte as (
Select *, row_number() over(partition by Id order by Id) as rnk
From temp)
Delete from cte
Where rnk 1

HAVING Clause implements in column operation. WHERE Clause implements in row operations. You messed it up, sorry
having is used on aggregated column where as where is used on actual column
Any SQL classes sir? I want to learn from scratch any tutorial do u have please inform.

dml commands are not rollback,but delete can be roolback .
its DDL not rollback
Hi Sir, as i understand once commit after transaction we can't rollback either Truncate or Delete or drop.
That's correct! Once a transaction is committed, you can't rollback changes made by Truncate, Delete or Drop operations.
