Based on expressions Built from table columns, constants, SQL functions, and user-defined functions. Examples) CREATE INDEX upper_dept_name_index ON dept2(UPPER(department_name)); SELECT * FROM dept2 WHERE UPPER(department_name) = 'SALES' The function-based index is used only when a query uses a particular function in the query otherwise the Oracle server may perform a full table scan.
