Here in this table I want to list employer which job is not expired and if expired all job posted by employer than only hide employer list I want it through mysql query to list in CI Framework.

I tried this

SELECT *
FROM employer_profile
WHERE u_id IN
        ( SELECT DISTINCT u_id
         FROM employer_profile
         INNER JOIN
             ( SELECT e_id,
                      COUNT(*)
              FROM employer_post_job
              WHERE dead_line >= CURDATE()
              GROUP BY e_id )
         INNER JOIN users ON employer_profile.u_id = users.id);

试试这个查询，如果您仍然遇到问题，请告诉我，因为我无法执行它。

Select * from users u 
          inner join employer-profile e ON u.id = e.u_id
          inner join employer-post-job epj ON e.u_id =epj.e_id
          where epj.expire date > '".date('Y-m-d')."'
