ERROR on SELECT VIEW

Question

Hi,
I created this view from schema TOM
CREATE OR REPLACE VIEW V_USERS
USER_ID, USER_NAME
AS
SELECT USER_ID, USER_NAME
FROM LOG_TAB A, LOG_USERS B
WHERE A.USER_ID = B.USER_NAME (+);TOM is the owner of the table LOG_TAB
SAM is the owner of the table LOG_USERS
From TOM, if I run the query:
SELECT USER_ID, USER_NAME
FROM LOG_W_BU A, AFM_USERS B
WHERE A.USER_ID = B.USER_NAME (+);The query answered correctly.
If I run:
select *
from V_USERS;I get this error:
ORA-01031: insufficient privilegesHave someone any idea?

Answer 1

you are using different table name from your view V_USERS and your plain query. on your view V_USERS you are using LOG_TAB and LOG_USERS. on the other hand you are using LOG_W_BU and AFM_USERS on your plain query. find out if you can do a simple select on SAM.LOG_USERS table, if you can add the schema name SAM to the LOG_USER table in your view and recompile them again.
CREATE OR REPLACE VIEW V_USERS (USER_ID, USER_NAME) AS
SELECT USER_ID, USER_NAME
  FROM LOG_TAB A, SAM.LOG_USERS B
WHERE A.USER_ID = B.USER_NAME (+);if you can't do a simple select on SAM.LOG_USERS table, try to login as SAM and grant SELECT privilege to TOM.
  grant SELECT on SAM.LOG_USERS to TOM;note: it always a good practice to include the schema name if the object is not a synonym.
