Question

我正在尝试从2个不同的表中进行选择，这会产生如下输出：

Punchdate | EmployeeCode | Name | Punch_in | Break | Lunch | Second_start | Break | Punch out
---------------------------------------------------------------------------------------------
11.08.2005      1021    John Smith   7:00    9:00     12:00    1:00         3:10      4:30

dbo.Punchintervals

employee(dbo.punchintervals.employee=dbo.employee.objid)
intime
outime
department/*(dbo.punchintervals.department = dbo.emprole.objid*/
/*(intime column has all the punches form all the departments,they need to be sorted trough the department column)*/

dbo.employee

employee/*(dbo.employee.objid=dbo.punchinterval.employee)*/
name
code

dbo.emprole

objid/*objid is just a vule example 10 (dbo.emprole.objid = dbo.punchinterval.department)*/
name/*(name of the role example: quality control, punch out, lunch,break)*/

到目前为止，这是我的最后一次尝试

SELECT     TOP (100)
  PUNCHDATE,CODE,name 
        ,( 
            SELECT  [sitewatch].[dbo].Punchinterval.INTIME
            FROM    [sitewatch].[dbo].Punchinterval AS PunchIn 
            WHERE   [sitewatch].[dbo].Punchinterval.DEPARTMENT = '10' 

        ) AS Startime 
        ,( 
             SELECT  [sitewatch].[dbo].Punchinterval.INTIME
            FROM    [sitewatch].[dbo].Punchinterval AS PunchIn 
            WHERE   [sitewatch].[dbo].Punchinterval.DEPARTMENT = '11' 
        ) AS break2 

FROM    [sitewatch].[dbo].Punchinterval,[sitewatch].[dbo].employee

Answer 1

SELECT * FROM dbo.employee
JOIN dbo.Punchintervals ON dbo.punchintervals.employee=dbo.employee.objid
JOIN dbo.emprole ON dbo.emprole.objid = dbo.punchinterval.department

如何在不同条件下多次选择一列？
