对MySQL代码进行阅读的时候，发现需要添加注释：
mysql注释符有三种：
1、#… 2、”- - …” 3、/…/
依次测试：
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、”- - …”
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 | +----+------+------+------+-----------+
3、/*…*/
mysql> select */*chazhoa*/ 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 | +----+------+------+------+-----------+
