Dbms_metadata ORA-31603

Question

Hi,
PL/SQL behaves different in SQL*Plus and in Apex.
Test 1 (anonymous block):
sql*plus:
========
OWL@NGPO>show user
USER is "OWL"
OWL@NGPO>DECLARE
2 l_sql_ddl VARCHAR2(32000);
3 BEGIN
4 l_sql_ddl := dbms_metadata.get_ddl('TABLE', 'JLI_TGEVALLEN_TFM', 'JLISTG');
5 END tst;
6 /
PL/SQL procedure successfully completed.
OWL@NGPO>
Apex:
====
Apex workspace parsing schema: OWL; the same as the user executing the code-block in SQL*Plus.
Home > SQL Workshop > SQL Commands:
executing the same anonymous pl/sql block as above results in:
ORA-31603: object "JLI_TGEVALLEN_TFM" of type TABLE not found in schema "JLISTG"
Test 2 (stored proc.)
CREATE OR REPLACE PROCEDURE owl.tst
AUTHID CURRENT_USER
AS
l_sql_ddl VARCHAR2(32000);
BEGIN
l_sql_ddl :=
dbms_metadata.get_ddl
('TABLE', 'JLI_TGEVALLEN_TFM', 'JLISTG');
END tst;
Now execute this procedure in sql*plus:
OWL@NGPO>exec tst
PL/SQL procedure successfully completed.
OWL@NGPO>show user
USER is "OWL"
in apex Home > SQL Workshop > SQL Commands:
begin
tst;
end;
==> ORA-31603: object "JLI_TGEVALLEN_TFM" of type TABLE not found in schema "JLISTG"
Any idea?

Jurgen

Answer 1

Jurgen - That is correct. Invoker's rights procedures don't work as they do in other places when the session user is APEX_PUBLIC_USER and the code is executed dynamically by the Application Express engine (a definer's rights package). That's just the way it is.
