bitsCN.com MySql的like语句中的通配符:百分号、下划线和escape%代表任意多个字符Sql代码 http://blog.csdn.net/yc7369/select * from user where username like '%huxiao'; select * from user where username like 'huxiao%'; select * from user where username like '%huxiao%'; _代表一个字符Sql代码 select * from user where username like '_'; select * from user where username like 'huxia_'; select * from user where username like 'h_xiao'; 如果我就真的要查%或者_,怎么办呢?使用escape,转义字符后面的%或_就不作为通配符了,注意前面没有转义字符的%和_仍然起通配符作用Sql代码 select username from gg_user where username like '%xiao/_%' escape '/'; select username from gg_user where username like '%xiao/%%' escape '/'; bitsCN.com
