Question

下面是一个很好的选择，但我被要求添加另一列，它让我难过。

我需要将来自连接的dbo.DEPARTMENTS.NAME的部门名称添加到dbo.MOBILEUSER.USER_ID到dbo.MOBILEUSERDEPTS.USER_ID，给予DEPT_ID，DEPT_ID连接到DEPT_ID上的DEPARTMENTS，允许选择DEPARTMENT NAME为移动用户。另一个问题是虽然每一行都有一个Employee USER_ID，但并不是每一行都有一个MOBILE USER或DESKTOP用户。员工和移动用户也可能有多个DEPARTMENTS，因此可能有多行。期望的输出是员工员工员工EMPDEPT用户用户门户网站PORTALUSER Mobile USER_ID上的EMP_ID PORTALUSER上的员工 DEPT_ID上的DEPT_ID PORTALUSERDEPTS上的EMPDEPTS 部门部门 Department LastName FirstName EmployeeStatus DesktopUser DesktopStatus PortalUser PortalStatus Department 样品 Spokane Doe John Active NULL NULL JDOE Active Seattle 伦敦史密斯大卫活跃David.Smythe活跃的DSMYTHE InActive牛津 Oxford Smythe David Active NULL NULL NULL NULL NULL

源表结构员工EMP_ID 姓名字 EMPDEPT EMP_ID DEPT_ID 状态状态T / A（终止/活动） DEPARTMENTS DEPT_ID 名称 USER USER_ID 用户名 ACTIVE状态T / F. PORTALUSER USER_ID 姓名字用户名批准状态T / F. PORTALUSERDEPTS USER_ID DEPT_ID

我遇到的问题是移动用户部门和员工部门 - 到目前为止我只能得到一个或者另一个。      SELECT
        dbo.DEPARTMENTS.NAME为部门，dbo.STAFF.LASTNAME为员工，         StaffStatus = CASE dbo.STFDEPT.STATUS                          当'T'然后'终止'                          当'A'然后'活跃'                          ELSE'警告!!'                       结束，         dbo.USERS.USERNAME AS桌面，         DeskTopStatus = CASE dbo.USERS.ACTIVE                            当'T'然后'活跃'                            当'F'然后'无效'                            ELSE''                         结束，         dbo.MOBILEUSERS.USERNAME AS MOBUser，         MobileStatus = CASE dbo.PORTALUSERS.APPROVED                           当'T'然后'活跃'                           当'F'然后'无效'                           ELSE''                        结束     从

TSQL选择返回太多或太少行的问题。可能需要一个联盟或类似的
