SQL模糊查询like concat

-- 1、匹配一个字段 比如user_name
select * from tb_user where user_name like '%'+ #{keyWord} +'%';
select * from tb_user where user_name like concat('%',#{keyWord},'%');

-- 2、匹配多个字段 根据user_name或user_code查询
select * from tb_user where (user_name like concat('%',#{keyWord},'%')) or (user_code like concat('%',#{keyWord},'%'));
select * from tb_user where concat(user_name, user_code) like concat('%',#{keyWord},'%');
