execute immediate statement

[kannan1983]

what is the difference between

TRUNCATE TABLE table_name

and

EXECUTE IMMEDIATE'TRUNC ATE TABLE table_name'

is there any performance issue between this two?
which is best to use in procedures?

[amitpatel66]

TRUNCATE TABLE <table_name> is a DDL statement.
You cannot use this directly in the PLSQL blocks.
So in order to use TRUNCATE TABLE <Table_Name> u need to execute this using EXECUTE IMMEDIATE 'TRUNCATE TABLE <Table_Name>' else the PLSQL bolck will throw an error.

EXECUTE IMMEDIATE clause is mainly used to execute dynamic SQL statements and DDL statements within PLSQL block.

EXECUTE IMMEDIATE you can frame the sql statment dynamically ,where u can also pass the table name dynamically to TRUNCATE .

EXECUTE IMMEDIATE uses late binding so performance might be faster.
