[@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 ??

[@priyankasuryawanshi6911]

Create Or Replace Procedure Proc1(table_name varchar2)
As
Begin
Execute Immediate 'delete from' ||table_name;
End Proc1;
execute Proc1('Exe_Tab2'); --when I tried to execute: execute Proc1('Exe_Tab2'); this command I am getting error that 'table or view does not exist'.. but table is already created with records.. can you please help.

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

Dynamic SQL how to use using class in SQL injection

[@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;

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]

@@TechCoach Thanks, this worked. Also, do you have any knowledge about how to import and use this procedure in Informatica Powercenter? Just curious.
