MySQL转义字符问题

Question

当我试图解决 This Question. 时我在表中创建了虚拟记录

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)

现在当我选择记录时，我没有得到任何结果，我尝试了很多类似的组合但没有运气。

例如:

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\\\%"
