Hi,
I have this table
+------------+----------+---------------+
| FacultryID | CourseID | DateQualified |
+------------+----------+---------------+
| 2143 | ISM 3112 | 9/1988 |
| 2143 | ISM 3113 | 9/1988 |
| 3467 | ISM 4212 | 9/1995 |
| 3467 | ISM 1930 | 9/1996 |
| 4756 | ISM 3113 | 9/1991 |
| 4756 | ISM 3112 | 9/1991 |
| 1111 | ISM 3113 | 9/1996 |
+------------+----------+---------------+
Which instructors can teach either 'ISM 3113' or 'ISM 3112', but cannot teach both?
In this table FacultyID 2143 and 4756 teach both, so I should get the result with FacultyID 1111 only.
How to list that with select command?
