我有两个表,我想查询两个表来获得一个报告。
POSITION
+-------------+---------------+
| position_id | position_name |
+-------------+---------------+
| 1 | E1P1 |
| 2 | E1P2 |
| 3 | E3P3 |
| 4 | E4P4 |
+-------------+---------------+
PEOPLE
+------------+-------------+--------------------+
| people_id | people_name | people_position_id |
+------------+-------------+--------------------+
| 1 | JOHN | 2 |
| 2 | MARK | 4 |
+------------+-------------+--------------------+
查询
SELECT position_id, position_name, people_name FROM position
RIGHT JOIN people ON people_position_id = position_id
当我使用简单的查询时,我只得到匹配的行,如何获取所有行?
我想得到这个结果
+----+----------+--------+
| ID | POSITION | STATUS |
+----+----------+--------+
| 1 | E1P1 | Empty |
| 2 | E1P2 | JOHN |
| 3 | E3P3 | Empty |
| 4 | E4P4 | MARK |
+----+----------+--------+
