select * from user where username like '_';
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
select username from gg_user where username like '%xiao\_%' escape '\';
select username from gg_user where username like '%xiao\%%' escape '\';
