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.

[@user-rh1hr5cc1r]

But we can use aggregated column in where by using nested query/sub query/cte

[@KSRDatavizon]

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).

[@user-rh1hr5cc1r]

[@sujeetmishra6892]

Could you please make video on SSIS tutorials and interview questions for beginners to advanced level please. Once you get chance

[@KSRDatavizon]

Sure team, we will plan to make videos on MSBI topics too..

[@awakenedsouls3206]

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 ?

[@ashutoshrai2717]

Where is this question in this video

[@nomulavijaya7500]

Hello sir….Are these still good for Power BI Analyst Role or do you have any updated Questions Videos on SQL and POWER BI.

[@KSRDatavizon]

these question will help for data analyst role interviews and Will upload more soon

[@akp3410]

in the first question you said the main difference between DDL and DML is DDL command can not be rolled back. I think thats not correct. begin tran Drop table Brands Rollback tran as above query works with rollback

[@EmDiAverageGamer]

Hi, Sir, I want to ask one thing. If I am able to answer till intermediate will I able to get a beginner-level job?

[@KSRDatavizon]

Yes, definitely

[@awakenedsouls3206]

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 ?

[@maheshtiwari2297]

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

[@shaiksk907]

Hi Sir, as i understand once commit after transaction we can't rollback either Truncate or Delete or drop.

[@KSRDatavizon]

That's correct! Once a transaction is committed, you can't rollback changes made by Truncate, Delete or Drop operations.

[@perfectionist6624]
