As per your lesson i have created stored procedure for the purpose of avoid the slow pwrformance in sql...Even i am facing the same problem after the creation of stored procedure..Please help me...I am struggling with this Past 10 days....
sir if possible please share your e mail ID or contact number...Please
Very clear and easy to understand.
Hi Venkat, very nice explanation. Could you please clarify the below question. The Global Temporary table will be destroyed as soon as the connection in which it is created closes. I don't think it will be there till the last connection referencing is closed.
Thank you sir! Much appreciated.
It looks like you have to enter your own data. How do you create a table with the data that is already in the database? Thank you!
Indeed - Great explanation...
Try to correct you sir well explained but in case of global temp table if you create a table in one connection and that connection is closed it will dropped automatically and you can't select query in second open connection.
+Sajid Hameed thanks for the info i checked it programatically ur right global temp table also gets delted.
Thank you for a wonderful session.
very well explained sir (y)
Very nice sir!! My Pranams to you
It seems very easy, i like your all videos. but It will better if you can keep less duration of video.
nicely explained..good communication
Awesome Sir ji ...
Thank you for your clear explanation
Hi Ben, you can't access the table #personaldetails from another query window. In the above query, we are not querying the table #personaldetails rather we are accessing the sysobjects table which stores information about temporary tables and some other info. We can access sysobjects table from any connection.
Hello sir, really good session. I have a question from this, can we have both schema binding and encryption for a function?
Hi Dineash, Yes you can have both. Make use of WITH SCHEMABINDING, ENCRYPTION while creating or altering function
Hello Sir,
i created store procedure with global temp table, and when i execute this store procedure in sql server , i can see the ##mytable in tempdb. but when execute same store procedure from web application then i'm unable to locate ##mytable in tempdb. but i'm able to retrieve data from ##mytable in web application.
where is the video about table variable ?pls let me know ?
Nicely explained.
thank you very much ❤️🌼
Hi i just want to know what happen when 1 global table is access by 2 connection at the same time and in both the connection update the global table so data is override or not in global table
I thought if two connections were open .We can't drop a global temp table from one of the connections unless it is the last connection .But I was able to delete global temp table from one of the connections even though another connection was still open . ?
If we have a stored proc that contains an insert into ##temp_table statement, do we need to add a line to drop the ##temp_table first before the actual insert into statement? I need to schedule the SP to run everyday. Thanks in advance.
Yes better do that, otherwise it will create a new temptable everyday which is not a good thing.
good explanation sir
i refer your video if unable to understand the concepts any where tq
Thank you
Hi, here one thing is not clear is, what is the need to having Temporary tables . Can you explain the use of it ?
mrudang dalal sometimes when we have subquery joins in our SQL query,it tends to take more time...so to get better performance we use this temp table and use it in join directly rather than using subquery
@@krishnendrabhattacharyya4609 is that the case. Then we are inserting values into temporary table manually. How come it resolve the problem when we had more values to insert. Everytime we have to do that right?
thank you
thank u so much
When do we use one over the other?
Thanks, Sir
when do we need these temporary tables?
Do we need any permissions to create a temporary table. We QA are general given read only access to query data.
Thanks
where is the video MAGIC tables ?pls upload that video in one interview ask that question to me....please upload that one..
temp tables can be widely used in stored procedures
BEST.
thanks
Can you please explain magic tables concept?
Hello' i don't clearly understand of temporary table, in which area we use temp tables.

Temp tablets and magical tablets are the same or different 🤔
Hello Venkat, I can access the local temporary from another connection when I copy and paste
Select name from Tempdb..sysobjects
Where name like '#persondetails%'
to the new query window, why is this?
You are amazing in the UK too ! Ben
Did you found the answer to this question.
Althought its not like accessing but we are able to list down from other connection too
what are Sql Jobs ?
How can I update the data in the table without affecting the base tables
