Hi,
I am again with a user problem.
Razz ....

I am having a User name - Sample
having n no of objects in it.
Having another user - usesample
This usesample is not having any object. But have privlige to select and perform DML operations on Sample.
Sample is having a table - Samplesizes
now I am connecting to usesample.
and

here starts my problem .....
Want to select samplesizes data as
select * from samplesizes;

Dont want to use access specifiers as (means following query)
select * from sample.samplesizes;

Is it possible to select objects of first schema(sample) from second scema (usesample) having privileges to access first schema(sample) without specifying the name of first schema(sample) name.

Thank you.

You could create SYNONYMS or once connected as USERSAMPLE issue:

ALTER SESSION SET CURRENT_SCHEMA = sample;

Ohh Thank you,

Really helped me to find the way....

Just check the following Trigger for using SAMPLE from USESAMPLE.
CREATE OR REPLACE TRIGGER db_logon_USESAMPLE
-- Now login as the user name password given to use the schema
AFTER logon ON DATABASE WHEN (USER IN ('USESAMPLE'))
BEGIN
-- This statement set the working schema for USESAMPLE user to SAMPLE user.
execute immediate 'ALTER SESSION SET CURRENT_SCHEMA = SAMPLE';
end;
