Error in creating dynamic view

Question

Hi,
I am using the following to create a dynamic view which will be created on runtime and conditions will be provided by user. Here is the code:
CREATE OR REPLACE PROCEDURE DYN_VIEW_PROC(PARA IN NUMBER)
AS
DEPT_NO NUMBER(3) := PARA;
DYN_QUERY VARCHAR2(1000);
BEGIN
DYN_QUERY := ' CREATE OR REPLACE VIEW DYN_VIEW
AS SELECT EMPNO,ENAME,DEPTNO FROM EMP_NEW
WHERE DEPTNO > :1 ';
EXECUTE IMMEDIATE DYN_QUERY USING DEPT_NO;
END;
But when i execute this code i got the following error:
SQL> EXEC DYN_VIEW_PROC(10);
BEGIN DYN_VIEW_PROC(10); END;
ERROR at line 1:
ORA-01027: bind variables not allowed for data definition operations
ORA-06512: at "SYS.DYN_VIEW_PROC", line 9
ORA-06512: at line 1
If i hardcode the condition in the defenation of view then it works fine. Any solution of it.

Answer 1

It looks strange.And more so, since the view name seems the same across each invocation (unless the example is missing that detail). So, if two users were creating this view one after the other and then subsequently try to use it, what would each user see in their output???
Not the rows based on their where condition, possbily.
You would create the view only once with all the necessary joins and any static conditions. Then users would use it as and when necessary, supplying their custom where condition on top of it.
What is the need you are trying to solve using this dynamic view creation?
