dynamically creating view in a stored procedure

How do I create a view in a stored procedure.  The stored procedure is passed a parameter, for example an id,  I will need to create the view name from this id and create the select statement using the id as a parameter in the where clause.  How is this done?

create replace sp_create_view(p_id number)


string = 'create view dyn' + p_id ' as
               select col1,

               from table where = p_id;'

First, I strongly encourage you to not do DDL in a procedure.

What is the view supposed to save you?

That said, given the example above (you have a typo):

string := 'create view dyn' + p_id ' as
               select col1,

               from table where = ' || p_id;

--after you build the string
execute immediate string;

Try something like that:

PROCEDURE usp_create_view(p_id NUMBER) IS
   v_sql LONG;
   v_sql := 'CREATE VIEW dyn'||p_id ||' AS SELECT col1, col2, FROM TABLE WHERE'||p_id||';'
   DBMS_OUTPUT.PUT_LINE('v_sql: ' || v_sql);

Open in new window

>>v_sql LONG;

NEVER use LONG's.  Use a CLOB.


I believe adding the semi-colon as part of the actual statement will generate a:
ORA-00911: invalid character

All that said, isn't that pretty much what I posted?

what do you possibly gain by building a view, then using that view as part of a select?

just go to the select and bypass the create/replace of the view

seems to me you have the impression that this will (somehow) be more efficient - it won't be
also seems to me you feel that a parameter is a necessary part of efficiency - it isn't
(a 'where clause' on a STATIC view could be just as efficient, perhaps more so)

Would you describe what it is you are trying to achieve please?

and although I really don't like the sound of this, if you are going to proceed down this path, use:

slightwv, you posted

string := 'create view dyn' + p_id ' as
               select col1,

               from table where = ' || p_id;
