Sir have created 24partitions of each hour table now I want to drop 20 partitions and insert data into 4 partitions in the same block using execute immediate please share your answer

[@TechCoach]

Created named partition so that you can easily identify and delete them

[@anirudhalluru8021]

We can run dml statements inside a procedure, but why its not happening with delete ??

[@shashank2004]

Nice explanation sir,pls make a video on all types of hints, reverse key index, deterministic function, pipeline function , performance tuning & tricky sql interview questions.

[@TechCoach]

Hints and reverse key index are in my plan and you should see a video on them soon. For performance tuning I will also recommend watching my video series on partitioning.Thanks a lot for the kind words :)

Hi Vivek, First of all, thanks for wonderful explanation. While executing a procedure where I am passing an integer into procedure block Egi: exec proc1(7);...This integer is nothing but an Employee ID of a certain table name as Employee. And when the block statement is getting executed, it is deleting the record. PFB procedure: Create or replace procedure proc1(Emp_ID) As Begin Delete from Employee where empid=Emp_ID; End; Here Employee is table having column as empid and empname. As per my understanding the sql over there is dynamic one where it is accepting runtime value 7. But it is getting executed successfully without using 'Execute Immediate' Could you please clarify what I misunderstood? Appreciate all your help!!!

[@TechCoach]

Thanks a lot for the kind words.Dynamic sql is slightly different from what you have mentioned.Dynamic sql statements are usually used when you don't know the table name or where clause or similar stuff.

[@ayush120793]

Thanks for the clarification Sir!!!...I got your point...

[@aishwaryaghumekar4819]

Thank you. This video was helpful. However I am trying to implement a query where I want to copy the data from 1 table to another and the table names have to be provided dynamically. I am using the below query and it's throwing error as: 'PLS-00103: Encountered the symbol "select * from " when expecting one of the following: . ( * @ % & = - + ; < / > at in is mod remainder not rem or != or ~= >=

[@TechCoach]

Hi Aishwarya, you are missing || before select.

[@aishwaryaghumekar4819]

Can you do videos on SQL injection concept

[@ramKumar-lf7er]

Dynamic SQL how to use using class in SQL injection

[@rohitjethwani626]

nyc video but I want to know more uses of execute immediate with examples.Please upload more video on it.

[@TechCoach]

If you want to execute a DDL inside a procedure you need to use execute immediate, if you want to create sql dynamically based on data driven scenarios then you need to use execute immediate

[@cybernetinc3775]

Will I be able to do this without execute Immediate? BEGIN FOR Row_Call IN (SELECT * FROM My_Tmp_Tbl) LOOP DELETE FROM My_Orig_Tbl WHERE user_id = Row_Call.user_id AND join_date = Row_Call.join_date; -- Some more task END LOOP ; END;
