Hi all,
I have a serious question about accessing tables over a database link.
I have three schema:
DATA@SOURCE
INTERFACE@SOURCE
WORK@TARGET
Schema DATA has one table called T1
The INTERFACE schema has select privileges on all tables from DATA. Furthermore schema INTERFACE has a logon trigger to change the "current schema" to DATA:
CREATE OR REPLACE TRIGGER TRG_A_LOGIN_SET_SCHEMA AFTER LOGON
ON INTERFACE.SCHEMA
BEGIN
execute immediate 'ALTER SESSION SET CURRENT_SCHEMA = DATA';
END;
The WORK schema has a database link to the INTERFACE schema called INT_DB_LINK.
I am now logged into schema WORK on the TARGET database and I am executing following statement:
select a from T1@INT_DB_LINK
-> it's working
Next I execute
declare
cursor c is
select a
from T1@INT_DB_LINK
where rownum<2;
begin
for r in c loop
null;
end loop;
end;
This is not working. Error message is ORA-000942: table or view does not exist.
But why?
Can anyone help me?
Thanks in advance
