在mysql中like模糊查询是不支持反斜线查询了,因为普通情况下在mysql中反斜线是转议的哦,下面我来给大家介绍如何利用MySql LIKE查找带反斜线的记录,有需要的朋友可进入参考。

使用 还是 \ 看你如何的定义字符串的。其实只有两处转义:PHP 中 和 MySQL 中。

PHP 中 如果你用双引号”" 定义字符串, 那么这里有一次转义。如果用单引号就不会转义。

$sql = “SELECT * FROM table WHERE col LIKE ‘%a\\%’ “;

这样实际上经过转义发给 MySQL 的是

SELECT * FROM table WHERE col LIKE ‘%a\%’;

用单引号则不会转义(除了单引号,当然变量也不会展开):

$sql = ‘SELECT * FROM table WHERE col LIKE ’%a\%’ ‘;

发给 MySQL 的也是

SELECT * FROM table WHERE col LIKE ‘%a\%’;
