Using QMF

=, ¬=, >, < -- Equality and inequality

To select rows that satisfy a condition that is based on equality or inequality, put the condition under the appropriate column.

You can display a report with everyone who has 10 or more years of service.

When you run this query:



Q.STAFF | ID | NAME | DEPT | JOB | YEARS         | SALARY | COMM |
--------+----+------+------+-----+---------------+--------+------|
        | P. | P.   |      |     | P. >=10       |        |      |

QMF produces this report:

    ID  NAME         YEARS
------  ----------  ------
    50  HANES           10
   210  LU              10
   260  JONES           12
   290  QUILL           10
   310  GRAHAM          13

If you do not specify an operator this way, the operator defaults to equality. You can write the following query to produce a report that contains all the managers.
