MySql的like語句中的通配符：百分號、下劃線和escape_MySQL

bitsCN.com MySql的like語句中的通配符：百分號、下劃線和escape%代表任意多個字符Sql代碼 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%'; _代表一個字符Sql代碼 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_，怎么辦呢？使用escape，轉義字符后面的%或_就不作為通配符了，注意前面沒有轉義字符的%和_仍然起通配符作用Sql代碼 select username from gg_user where username like '%xiao/_%' escape '/'; select username from gg_user where username like '%xiao/%%' escape '/'; bitsCN.com
