The following query requests information about particular columns in the employee and department tables (note that each column reference is fully qualified with its table name).

     HELP COLUMN employee.name, employee.dept_no, department.dept_no 
     FROM employee, department;

The return from the preceding query lists each column in the order in which it was specified; therefore, the first dept_no column listed is for the employee table, the second is for the department table.

     Column Name   Type    Nullable 
     -----------   ----    -------- 
     Name           CV       N 
     DeptNo         I2       Y 
     DeptNo         I2       N
