Basically Dynamic SQL means, you'll construct a SQL
statement dynamically while runtime and run it.
Why this needed: Since the stored database objects
(Procedures and Functions and others) will be compiled while
creating and stored inside a database.so everything has been
checked already. so whenever you make a call to these
programs they will directly run withou compiling second time.
since it runs without compiling you cannot use DDL commands
inside a stored program.
So to avoid this you can directly mention Execute Immediate
keywords in front of a SQL query dynamically in your
block.so that it'll work this time.
Hope this helps.
