To create a data table with a stored procedure:
Note that you must add Authid current_user if you create a table that already exists, the stored procedure continues to execute, but if you do not add this key statement, the stored procedure will appear unexpectedly.
This statement is equivalent to assigning permissions.
Example 1
The statement is created as follows:
Copy Code code as follows:
Create or replace
Procedure sp_create_mnl (i_id varchar2) Authid Current_User as
/*********************************

Enter the parameter description:
