SELECT statement Processing in an Oracle Database - DBArch Video 7

I have watched all your series and i really like your style of teaching.
Can you do a video series on Postgresql

Amazingly explained sir

Thank you Sir

Short and informative video

Hi Sir,
Your Explonation is very well and I have one doubt which background process will read data from database and read into the DBcahche.

SUBSCRIBED YOUR CHANNEL🙏 I'm pretty feeling comfortable listening to your classes. Thank you sir.

unable to concentrate due to background music in the video even though you explained it nice

I have attended core dba in multiple institutes and noone is not as clear as you. Your way of explanation is so easy to understand and concepts are explained very clearly...keep up the good work

Excellent explanation. Thank you🙏 sir.

all the videos are very helpful, Thank you so much sir
if you have any Rac Dataguard ASM Videos Link please ?

Kindly remove background score its a distraction

Hi Ramkumar,

How to get the details of sql query from server side.

Note: database max number of processes reached. So, we need to kill some of the queries

when and where is the hash number for your SQL statement created before the database does the shared pool check for a shared area with an exist sql ID? Thank you

This video is the most helpful and concise video on SQL execution. Thanks man

Respects

Sir as you said hash is generated again for the same statement on next execution meanwhile oracle documentation says its unique for the same statement because this hash is searched out in shared sql area to avoid a statement from being pasred again on next execution. Please correct where I'm wrong to understand about hash.

that is awesome thanks a lot...but one question i have is at the time the blocks are send to the buffer cache to process and give data to the app or user. the question is where is the app or user viewing the info ???
is it from the app which the data was send from the server to the app or the app is in the database getting data in the instance still. meaning the process that the app is doing with the data its send back to be updated on the server or instance. they where all processing from the instance all along. so the processes are internal in the instance?

Hi, can u explain please hard parse and soft parse

Thank you sooo much, superbly explained and understood.

Thanks a lot but where is the usage of result cache?

Thank you very much for explaining the subject of oracle in a way that everyone can understand.

Best explanation, it would be even more better if that disturbing background music wasn't included.

Good explanation ...DONE...

Sir what is the future of pl sql

Thanks

very best explanation (Y)

Okay syntax and semantics cleared…. doesn’t this privilege check also actually comes under semantic checks legally? I mean u can make anything but still… I think semantics is about the legal validity...and privileges is one of them I suppose.

Anyway doesn't mean much if in oracle u do things like that but was jus curious. :)

You are Amazing

"If you can't explain it simply, you don't understand it well enough" ... You have explained simplest of all .... You understand it perfectly. The auditorium is happy to follow such great videos for Oracle.

Best explanation Sir. /\ I was looking for a proper guidance on this. The way you explain every details seems so easy. Thank you.

You are the best of all...My heart satisfies with ur explanations with valid reasons that u provide..please make the practical scenarios also for all ur videos
...and also please make the videos on Oracle Apps DBA with practical scenarios..

Hi Sir, are you giving any online training if yes can you please share the details
Thanks

Best explanation I ever seen..I was searching for right guide for oracle and I found it..Thanks for your effort..We are expecting more videos.

Excellent Tutorial

Everything is nice. Presentation, Technic, Explanation. May god bless you.

Hi Sir,
Kindly upload a video of " HOW TO CHANGE PLAN HASH VALUE OF A QUERY IF IT TAKES BAD PLAN HASH VALUE INSTAEAD OF REGULAR " and explain it if any impact on execution query.

Sir ji thanks a lot.
You are beyond best. I don't have word to adjectify you.
Namaste

Good overview. Thank you. What happens when a hash is generated and later there is a change in DDL? will the hash be deleted and goes for another hard parse??

Example : 1. hash created for select empid from emp;
2. Query executed and result returned.
3. Ddl executed to drop empid column
4. Reissue the same command..

When step 4 executed hash would be same as step 1.. So it should ideally go for soft parse but how this scenario would be handled.??

nice background music but pls reduce the volume , sometimes its overlapping your voice.
Nothing we can say about your teaching skills.hats off

Really, very nice explanation... You explained such a complex stuff in a very simple manner.. Thank you Sir :)

Thank you for your excellent video. I have a question: "How does oracle find table blocks in datafiles ? If table exist in buffer cache, how does oracle find it ?" Thanks.

Tq

Best teacher ever... God for dba folks

Sir!! I salute you... you know what you are teaching, congratulations

Sir,
Thank you for this nice video.Very well explained.
I have a doubt what will happen if the buffer cache is smaller than the table size. Will it get loaded in the memory?
Thanks

You are the best :) :) :)
