Some simple SQL windows function questions such as using DENSE_RANK, Partition BY are often checked in data challenges.

[@SimplilearnOfficial]

Thanks for sharing your input.

[@AirahandMama]

I have applied for entry level data analyst role. Prepared for the interview with simplilearn. I got exactly same questions. I was sooo happy and confident. Just finished my interview a minute ago. Waiting for the result.

[@haiyingwang5987]

Super useful content and tightly structured. Better audio quality would've been even more awesome!

[@blakebagwell8871]

For question 42, I believe you should sum based off of the LineTotal instead of the UnitPrice. Reason being that you ask for total units sold greater than 1.5 million and each SalesOrderID could have multiple units of the same product in it. The unit price only picks up one of those units within each SalesOrderID while the LineTotal picks up the price of all units within that order. Line #2 of the sales order total table is an example, that order has 3 units of the same product ID and the unit price line only picks up one of those units. So the sql statement would be the same, just change SUM(sod.UnitPrice) to SUM(sod.LineTotal) in both the select and having statements.

[@prettymimiBakaka]

Hi, In question 33, why the query has the having clause avg(mkt_price)> 50 whereas the question asks for the average market price to be greater than 100? Am I missing something?

[@alvarochinchayan6035]

Most probably just a typo, as you can see the result has avg_price > 100. If not, it would have reflected currencies whose avg_price > 50 as well.

[@SimplilearnOfficial]

"Hi, Apologies for the error. Yes, it should be avg(mkt_price) > 100"

[@deeplysuperficial8132]

I was also confused. Great information otherwise!

[@zehaolyu9570]

Super useful!!!

[@SimplilearnOfficial]

Glad it was helpful!

[@shivaragm964]

Can u plz say which bank intervw it was?

[@tobibonike]

kindly explain the difference between data analysis and big data analysis, for me. Thank you.

[@splashoui3760]

The difference is basically the amount of data and the velocity of data streaming at the same time in case the data is coming in real time or with batches.

[@SimplilearnOfficial]

Stick around as we have a tutorial on the same coming up soon.

[@nickheyer]

How does this video have 100k views, but only 41 (now 42) comments? That is some data I'd like to analyze.
