Create data tables with stored procedures:
Note at creation that authid current_user must be added. If the created table already exists, the stored procedure continues to execute, but if this key statement is not added, the stored procedure will have an exception.
This statement is equivalent to assigning permissions.
Example 1
The creation statement is as follows:
create or replace
procedure sp_create_mnl(i_id varchar2) authid current_user as
/*********************************
Name: sp_create_mnl
