MariaDB错误?像逃脱一样 [英] MariaDB Bugs? LIKE Escaping Broken

问题描述

服务器版本:10.1.21-MariaDB-1〜jessie

Server version: 10.1.21-MariaDB-1~jessie

select 'a%b' like '%\%\%';
+--------------------+
| 'a%b' like '%\%\%' |
+--------------------+
|                  1 |
+--------------------+
1 row in set (0.00 sec)

like子句表示通配符+文字％+文字％"，但与"a％b"匹配.

the like clause represents 'wildcard + literal % + literal %' but it matches 'a%b'.

或

select 'a%b' like '%\%\%\%\%\%';
+--------------------------+
| 'a%b' like '%\%\%\%\%\%' |
+--------------------------+
|                        1 |
+--------------------------+
1 row in set (0.00 sec)

MySQL 5.5.38的两个语句均返回0. MariaDB的语法是否不同?

MySQL 5.5.38 returns 0 for both statements. Is the syntax of MariaDB different?

添加

@rahul指出语法错误，所以我创建了一个虚拟表并运行

@rahul pointed that the syntax is wrong, so I created a dummy table and ran

SELECT * FROM `table1` where 'a%b' like '%\%\%';

与表中的每一行匹配.

但是，当我运行时，field1 ='a％b'的行不匹配

However, a row with field1='a%b' doesn't match when I ran

SELECT * from `table` where field1 like '%\%\%';

现在要在10.1.22上进行测试.

Now going to test on 10.1.22.

推荐答案

似乎这已在10.1.22中修复.

It seems this is fixed in 10.1.22.
