Accessing a table without specifying the schema name

Question

I have a schema called GBO_ARC_SCHEMA, in which I have one table called TEST_EMP, and I have two users say USER_A and USER_B.

First I connected to USER_A and fired below query

select count(*)from TEST_EMP;

count
-----
20

After that I connected as USER_b and fired below query but it is giving an error, saying that table or view does not exit

select count(*)from TEST_EMP;

But if I use scma.object name it is allowing me to query like below

select count(*)from GBO_ARC_SCHEMA.TEST_EMP;

but as per my requirement I don't want to specify schema name.

can somebody help me out?

Answer 1

If you want all users to be able to select from the table without qualifying with the schema name, you want to create a public synonym:

create public synonym TEST_EMP for GBO_ARC_SCHEMA.TEST_EMP;

If you only want user_b to omit the schema name, you want to create a private synonym WITHIN user_b's schema (that is logged on as user_b)

create synonym TEST_EMP for GBO_ARC_SCHEMA.TEST_EMP;

If you insist on not using synonyms, then, after logging in, do a

alter session set current_schema = GBO_ARC_SCHEMA;
