對MySQL程式碼進行閱讀的時候，發現需要加入註解：
mysql註解有三種：
1、#… 2、”- - …” 3、/…/
依序測驗：
1、#…
mysql> select * from person; #chazhao +----+------+------+------+-----------+| id | name | sex | age | addr | +----+------+------+------+-----------+| 1 | Jone | fema | 27 | xianggang | | 2 | Lily | fema | 25 | taiwan | | 3 | Bobe | male | 25 | ximan || 4 | Kity | fama | 20 | beijing | +----+------+------+------+-----------+
2、」- - …”
1、#…mysql> select * from person; --chazhao +----+------+------+------+-----------+| id | name | sex | age | addr | +----+------+------+------+-----------+| 1 | Jone | fema | 27 | xianggang | | 2 | Lily | fema | 25 | taiwan | | 3 | Bobe | male | 25 | ximan || 4 | Kity | fama | 20 | beijing | +----+------+------+------+-----------+*…*/
