超简单问题，求快速解决。。

SQL code


ALTER VIEW [dbo].[V_Idata] AS
SELECT DoradoReport.中文姓,DoradoReport.中文名,DoradoReport.SAP工号,DoradoReport.员工原工号,SAP.employee_ID,notes.PersonID,notes.email,
CTS.cts_ID,RMS_LOGONNAME,Domain_User.user_id
FROM DoradoReport LEFT outer join SAP ON DoradoReport.SAP工号=SAP.employee_ID
                  LEFT outer join notes ON DoradoReport.员工原工号=notes.PersonID or DoradoReport.SAP工号=notes.PersonID
                  LEFT outer join CTS ON DoradoReport.员工原工号=CTS.cts_ID OR DoradoReport.SAP工号=CTS.cts_ID
                  LEFT outer join RMS ON DoradoReport.员工原工号=RMS.RMS_ID OR DoradoReport.SAP工号=RMS.RMS_ID
                  LEFT outer join Domain_User ON DoradoReport.员工原工号=Domain_User.user_id WHERE Domain_User.User_kind='Domain Users'

我以DoradoReport表为中心进行联接，原则上应该是DoradoReport表不变，其他表根据关联主键关联进来构成张大表，但是我关联了最后一行后，行数变成了与Domain_User匹配后的行数，没匹配到的就没出来了，我需要他全部出来，请高手帮忙解决!

这个问题很高深的，我反正看不懂，来打一下酱油
