Straight to the point, you answered the question and visually showed the effects of using IQueryable using the profiler. Very well done!

[@ladanseyedzadeh1090]

You are the best instructor in the field of programming based on my experience, I wish I had a professor like you when I studied CE at University. I can not help but admire your natural talent to simplify complex concepts.

[@kopilkaiser8991]

In my junior dev job, they were using different places interechangeably these two collection types: IEnumerable & IQueryable. And I was very confused with the requirement of doing such implementation. You have clarified my doubts and questions. And it makes a big difference of using the two different types of collections when we are mutating the various different objects. Thank you so much for taking the effort and time to deliver such essential information.

[@AhmadElkhouly]

Thank you. This 7-minute video indirectly answered a question I've been trying to find an answer to for a while. Subscribed. 🎉

[@mrmanualways]

awesome bro.. can't say thank you enough to all youtube teachers .. Happy 2019

[@MrTanveer416]

Excellent explanation within a very short time.

[@zaharivaklinov]

Great video with the answer on the question! I failed an interview the other day due to some failed answer attempts, one of which was about the difference between IEnumerable and IQueryable...

[@cristianfarcas3272]

I've been looking for this kind of video for a couple of hours already. great job!

[@CezarLisboa1990]

Perfect! Great video! Very useful for deciding to use both interfaces. Thank you!

[@maha2818]

Awesome sir. You are great. Nicely explained the topic and very easy to understand the difference. Please keep your awesome teaching. Thanks

[@pearsonkevin4699]

Short and sweet yet taught ME the difference! Thank you!!!

[@thishandharmakeerthi5327]

This channel is one of the most underrated channels in youtube.

[@suvmatrix]

Awesome way of showing the difference. That's what I like in your content

[@SimplefundBaba]

Great video, i was always confused to these concept. but today i am fully clear on this concept.

[@musabalriani550]

Thanks a lot ,This is the best advice in my day.

[@malkitsaggu]

Very clear explanation. Thank you.

[@BrutusPalmeira]

Great video as always. Of course an example of in memory would have been nice too. If we have an in memory list and we use iqueryable instead of ienumerable, do we get any drawbacks?

[@ajaypanse4489]

Hi Shiv, Your videos are very good to understand the concepts. In one of the interviews, along with this difference I was asked which one is having thread safety feature or thread safe. I couldn't answer it properly. I tried to search on net but didn't get proper answer. Can you help me to get this answer so it will help me to clear that concept. Thanks

[@rhoonah5849]

Excellent video. Very simply explanation of the differences between IQueryable and IEnumerable with EF. Quick question though... if you applied a ToList() on the end of where you called dal.Employees so it was dal.Employees.ToList(), would all calls now be in memory? So would you only have gone to the DB once to load the Employees table and then all filters are just applied to the in memory list? Thank you.

[@rezkhan3366]

Great explanation. Thanks!

[@RaterisimoCBA]

Good video ! Simple and concrete answer.

[@rutujamokashi6389]

It's really very helpful for me...

[@tamagofukunaga]

Great explanation and information, thank you!

[@prasadmadushan]

Thank you for your great explanation.

[@govindwaghmode6379]

Great explanation sir. Thank you so much.

[@bernardfitzgerald5697]

Might be worth noting that the delay in querying the database could lead to adverse results if there are table changes between creating the interface and applying the filter. Good video though

[@OT-tn7ci]

if there are table changes, and if IQueryable doesn't work, most likely even IEnumerable won't work.

[@4bitmultiplexer]

Very excellent explanation...

[@tahatemuri8170]

Good show and crystal clear

[@EMWMIKE]

I think it is missed that depending on what indexes exists on the table in database. Iquariable is not allways the better choise in a high performance volume environment. So many times it is better to hit indexes and pull that data, then to the filtering on client side

[@vikasverma4215]

Now clear... Love it.

[@sujitkumarjha7720]

Brilliant 👍

[@MSMOTOVLOGS]

Nice video. To the point. No BS

[@noellangcauon7133]

Thanks bro! keep uploading useful information like this!

[@RahulSharma-ps1rf]

Hello Sir, I have one question. We have 2 options to get data from DB using EF ie. List data = _context.tableName.AsQueryable().Where(x => x.id == 33144).ToList(); and List data = _context.TableName.Where(x => x.id == 33144).ToList();. Both have same impact when we see in SQL profiler then why to use IQueryable?

[@MohammedDawoodAnsari]

Another use case would be to add filters on run time, for example in your query if there is one more parameter lets say as name, so if name filter needs to be applied based on condition, then also you can use IQuerayable

[@AShahabov]

Thanks for good explanation!

[@bntdgp]

Unique Explaining

You are awesome 😎

[@claytonmcgill875]

Thank you so much for this !

[@avinash23525]

Nice. well explained !. can't we filter while loading Employee table or using linq ?

[@manoranjansahoo9721]

Thanks for making clear understanding, Please make video on visual studio 2019 tools, its features, tips & hidden tricks etc.

[@sanketshahane5778]

Very Nicely Explained it sir, But I have one small query regarding IQueryable, may be it is silly question (don't mind)..!! If I am declaring IQueryable variable and initializing (getting data from DB) Apply where conditions and filter the data, and in next line I am getting a count() of that variable then there will be 2 DB call (1st for getting data with filtered and 2nd for getting count(*)) or only 1st DB call..?? Ex: IQueryable results = db.GetTable().Where(Expression); var recordList = results.ToList(); int totalRecords = results.Count(); Please help..! Thank you in advance..!!

thanks for this vid

[@SonuSingh-nj6vp]

Nice

[@nandishdhadd5834]

In simple words, using Iqueryable will defer query execution..

[@questpondvideos]

yes sir , but until we do not see it , simple words are not simple :-) happy learning.

[@artak9439]

If I remember IEnumerable uses expression tree and IQueriable uses tree traversial.

[@lovelybuck]

Super

[@learningislife2934]

Sir please make interface video Please 🙏

[@questpondvideos]

Our video on Abstract class & Interfaces you can watch below :- kzbin.info/www/bejne/ZnbRhIN4i9eVfZI

[@expertreviews1112]

Hi sir, but I thought interfaces are abstract and don't contain any logic then how are the differences highlighted in the video work.

[@questpondvideos]

Interfaces are pointing to a list or some concrete collection

[@expertreviews1112]

Thank you. Can you point out a resource where I can get this type of info?
