How can I create stored procedure from within Python script?

Question

I am looking to way to create an oracle stored procedure in Python.

I know, cursor.callproc in cx_Oracle exists to call the existing stored procedure, but I am looking for a way/method to create an Oracle stored procedure in Python.

Answer 1

Just use execute() with the SQL CREATE OR REPLACE command.

To check if the procedure was valid, you need to query a base table like user_errors .

with connection.cursor() as cursor:
    cursor.execute("""create or replace procedure x(a in number) as begin BOGUS end;""")
    cursor.execute("""
            select name, type, line, position, text
            from user_errors
            where name = 'X'
            order by name, type, line, position""")
    data = cursor.fetchall()
    print(data) 

The output is:

[('X', 'PROCEDURE', 1, 41, 'PLS-00103: Encountered the symbol "END" when expecting one of the following:\n\n   := . ( @ % ;\nThe symbol ";" was substituted for "END" to continue.\n')]

We are looking at how a future version of cx_Oracle can directly expose Oracle's 'success with info' flag and the compilation error message.
