Need for Dynamic SQL:
You need dynamic SQL in the situations as follows:
1) You would like to execute a SQL data definition statement (like CREATE), a data control statement (like GRANT), or a session control statement (like ALTER SESSION). In PL/SQL, these statements cannot be executed statically.
2) You wish for more flexibility. For illustration, you might desire to defer your choice of the schema objects until the run time. Or, you may want your program to construct various search conditions for the WHERE clause of a SELECT statement. A further complex program might prefer from the various SQL operations, clauses, etc.
