Hi Michael!
Let me quess: You'r calling your procedure, while you're connected with another schema-sure, 'cause
you'll copy the view !!!

Make sure while using dynamic sql that
1) the user which is calling your procedure has the system privileges to create a view
2) the user which is calling your procedure has received the object privileges to access to the base tables/views of the view,

you wish to create!

Even if the proc-caller will temporarely receive the same rights as the proc-owner !!! The proc-caller is executing dynamic sql and so, his own system- and object-priviliges will be checked !!!!!

<BLOCKQUOTE TYPE=CITE>Hi,

I have created a procedure that creates views in a schema.  It
does this
 by extracting the view definitions from tables into a varchar2 field,
 and then calls the dbms_sql package to create the view.

Whilst the PL/SQL works quite happily when executed at the sql prompt,
 when I store it in the database as a procedure and execute it, I get
 insufficient privilege errors being raised by the DBMS_SQL package.

This strikes me as a little strange as the procedure is stored in the
 same schema as the views, and their underlying base tables.  DBMS_SQL
is
 supposed to inherit the privileges of the schema where the procedure
is
 stored.

Has anyone had this problem, and maybe found a workaround for it ?

We are running Oracle v7.3.2.3.0 on and AIX box.

Thanks,
