Oracle Database Interview Question:

What Privilege Is Needed for a User to Insert Rows to Tables in Another Schema?

Submitted by: Administrator

For a user to insert rows into tables of someone else's schema, he/she needs the INSERT ANY TABLE privilege. The following tutorial exercise gives you a good example of granting "dev" to insert rows in "hr" schema:

>.insqlplus /nolog
SQL> CONNECT DEV/developer

SQL> INSERT INTO hr.jobs
VALUES ('DV.ggl', 'Dev ggl Consultant', 7700, 8800);
ORA-01031: insufficient privileges

SQL> disconnect
SQL> connect SYSTEM/globalguideline

SQL> GRANT INSERT ANY TABLE TO dev;
Grant succeeded.

SQL> disconnect
SQL> CONNECT DEV/developer

SQL> INSERT INTO hr.jobs
VALUES ('DV.ggl', 'Dev ggl Consultant', 7700, 8800);
1 row created.

As you can see, "dev" can insert rows in any schema now. But you should be careful when giving this privilege to a regular developer.
