how to grant role acces to specific schema

Question

I am new to Oracle and i am struggling with the permissions. I created some tables with user called ADMIN on a specific tablespace. The tables are in the schema ADMIN now. I want access this tables from another user called TESTUSER which is in a role called TEST.

Is there a way to grant this role called TEST access to the schema ADMIN? Or a way to grant access to the user for this schema? I aslo want that the ADMIN tables show up in the sqldeveloper under the TEST user.

I already used some commands to try this out but it doesnt work. Eg.

GRANT SELECT on ADMIN.TABLE1 to TEST

What do I have to do?

Solution

Assuming:
TEST, ADMIN are users
ADMIN is the owner of table TABLE1
TESTROLE is a role

Connect to the schema ADMIN then run command:

GRANT SELECT on TABLE1 to TESTROLE;

Then run the command:

GRANT TESTROLE TO TEST; 

connect as TEST user and check:

SELECT * FROM ADMIN.TABLE1;
