what are Dynamic SQL statements?..

Answer / naresh

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.

Answer / thanvi

Both compilation and execution happens at the time.It will be useful where we don't know (the value of col_name or table_name) till runtime.
-Compilation means checks for the syntax.

Answer / vishal kumar

Sql statement should be written in quotes like

'select table1.col1, tabel2.col2 from table1,table2 where
table1.col3=table2.col4'
and we can execute through below command "execute immidiate"
EXECUTE IMMEDIATE 'select table1.col1, tabel2.col2 from
table1,table2 where table1.col3=table2.col4'

it execute at runtime, means its not allowed as static.
