[krishnenduchakraborty]

One of the most underrated channel for SQL Tutorial. Keep it up bro! 🙏👍

[vishalchauhan]

I have already gone through your previous video, due to which i was able to solve this problem before watching solution part .Thank you for the awesome content !

[osoriomatucurane]

Great tutorial, sir. Getting the running total or cumutive is very common in business and statistics. Honestly i feel that SQL must have a very simple straitforward way of getting that instead of a cumbersome or convulte way!

[anuragshrivastava]

awesome sql interview video series kindly continue as per 2024 standard interview question

[vijaygupta]

Too good way explained.
Request you please make same kind of videos on other topics also

[creativedeep]

[vaishalivajpayee]

Thanks for this concept. Very well explained!!

Hey Ashutosh,

For me :

--- First table -->

select *, sum(Sales) over( order by date) from runningSum;

-this is also working and I haven't gone through your row between video but can you check if that is important over her.

---Second Table--->

select *, sum(sales) over (partition by State order by date ) running_Sum from runningSum2;

-same for this one

[aishwaryapattnaik]

Hey Ashutosh can you tell me how to find the rolling sum or moving average in case the some of the dates in between don't have their respective Sales values.

[mohdqamber]

same question ask to me in SQL interview

[saurabhagarwal]

select *, sum(Sales) over(partition by State order by Date) from running_sum_partition;
select *, sum(Sales) over(partition by State order by Date rows between unbounded preceding and current row) from running_sum_partition;
if i execute both query separetly getting same answer. In second query if we don't use rows between still getting same answer.
could you please clarify it?

[tejaswinerella]

Hi Ashutosh

can you please provide the exact table or exact Excel sheet (in that github link not able to find the table)

[MedusasRomance]

I am not able to understand why unbounded following doesn't work, if unbounded preceding has no problem

[jiteshshewale]
