MySQL的轉義字符問題

Question

當我試圖解決This Question.我創建了一個表

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) 

現在的僞記錄，當我選擇記錄，我越來越沒有結果，我曾嘗試與像許多組合，而且沒有運氣。

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

使用三重斜線：

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

Answer 2

或者使用INSTR()代替

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