在Join中使用FIND_IN_SET

$d[‘a.cold’] = 2;
$d[‘b.postid’] = $up_id[‘postid’];
$d[‘b.f_id’] = $up_id[‘id’];

$d[‘workintime’] = array(‘lt’,$lastday);

$down2 = db::name(‘admin_user’)
->field(‘a.*,a.id as user_id,b.*’)
->alias(‘a’)
// ->join(‘role b’,’a.roleid= b.id ‘)
->join(‘role b’,’find_in_set(b.id,a.roleid)’)

->where($d)
->select();
