MySQL的转义字符问题

Question

当我试图解决This Question.我创建了一个表

create table mytable(data CHAR(30)); 

INSERT INTO mytable VALUES('d\\one'),('d\\two'),('d\\three'); 

SELECT * FROM mytable; 
+---------+ 
| data | 
+---------+ 
| d\one | 
| d\two | 
| d\three | 
+---------+ 
3 rows in set (0.00 sec) 

现在的伪记录，当我选择记录，我越来越没有结果，我曾尝试与像许多组合，而且没有运气。

例：

SELECT * FROM mytable WHERE data LIKE "d\\%"; 
Empty set (0.00 sec) 


SELECT * FROM mytable WHERE data LIKE 'd\\%'; 
Empty set (0.00 sec) 

Answer 1

使用三重斜线：

SELECT * FROM mytable WHERE data LIKE "d\\\%" 

Answer 2

或者使用INSTR()代替

SELECT * FROM mytable WHERE instr(data, 'd\\') = 1
