COUNTRY_ID column contains only three possible values: 1111, 2222, and 3333.
You execute the commands:
SQL> EXECUTE DBMS_STATS.GATHER_TABLE_STATS('SH','CUSTOMERS');
PL/SQL procedure successfully completed.
SQL> CREATE INDEX COUNTRY_IDX ON CUSTOMERS (COUNTRY_ID);
Index created.
You then perform a series of INSERT, UPDATE, and DELETE operations on the table.
