• 先看一下常规的插入:

insert into user VALUES (125,'王小'二'',98);

insert into user VALUES (124,'王'小'二',98);

• 这样会报错:

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server 
version for the right syntax to use near '二'',98)' at line 1

• 引起原因:
  mysql会自动把’‘进行配对,这样第一条sql就是字符串’王小’后面突然出现个字符串,这样就会报错,字符串要用’’.

• 解决:添加转义字符

insert into user VALUES (125,'王小\'二\'',98);

insert into user VALUES (124,'王\'小\'二',98);

• 插入结果:
