我试图在SQL Server中链接几个表.下面的代码显示了到目前为止我如何将表链接在一起:

select *

left join learner l on l.learnerid = profileid
left join learner_levels ll on ll.learnerid = l.learnerid
left join subjects s on s.subjectid = ll.subjectid
left join learner_group lg on lg.learnerid = profileid
where ll.archived = '0' and ll.completed = '0'
order by surname asc`

select *
from profile
left join learner l on l.learnerid = profileid
left join learner_levels ll on ll.learnerid = l.learnerid
left join subjects s on s.subjectid …
