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://hovertree.com/
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_，怎麼辦呢？使用escape，轉義字符後面的%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 '/';
