从另一个表中的多个记录在一个表中创建1条记录

我试图用另一个表中的多个记录填充一个表。 我有一个表，其中包含员工时间表的记录。 每条记录包含一个事件的日期和时间，该事件涉及1名员工： 字段是：

ScheduleID = unique record identifier
ScheduleName = identifies the schedule
ScheduleLine = identifies the line on the schedule grid
Position = the schedule employee position filled (not necessarily the 
same as the employees postion)
ADP_ID = employee identifier
ScheduleBeginDay = what day of the week the schedule begins (usually 
Monday)
ShiftName = shift worked
ScheduleStart = date and time employee is scheduled to clock in
ScheduleEnd = date and time employee is scheduled to clock out
RecordActive = is record active or deleted

我需要将其转换为看起来像应用程序以及报表中的时间表网格。 那是网格中的1行=最多7条先前的记录（周一至周日）

以下代码有效，但仅当第一天有人在该位置时才有效。 通常但并非总是如此。 问题是“我如何在时间表上为每行（职位）创建1行输出（只要至少1个人在一周中至少一天在该职位上至少工作1天）？

此代码用于根据个人记录创建每周计划。 在实际的实时代码中，实际上将从屏幕上的字段或计算出的字段填充硬编码的字符串（时间表名称，开始日期）

--create a temp table to hold basic data for each line on the schedule
--this is referred to as day0 and will later be joined with data from days 1 - 7
CREATE TABLE #temp_dates (
    ScheduleName VARCHAR(MAX),
    ScheduleLine int,
    ScheduleBeginDay VARCHAR(MAX),
    ShiftName VARCHAR(MAX),
    Position VARCHAR(MAX),
    ScheduleStart datetime,
    ScheduleEnd datetime
);

--create 1 temp record for each line on the schedule and populate the basic data
insert into #temp_dates
(ScheduleName,ScheduleLine,ShiftName,Position,ScheduleBeginDay)
select distinct ScheduleName,ScheduleLine,ShiftName,Position,ScheduleBeginDay
from Schedules 
where ScheduleName = 'Walk-In Center April Wk 1 2019'
group by ScheduleName,ScheduleLine,ShiftName,Position,ScheduleBeginDay
order by ScheduleName,ScheduleLine,ShiftName,Position,ScheduleBeginDay

-- set date for start of weekly schedule 
declare @startdate as datetime
set @startdate = '04/01/2019'

--populate the schedule start and end times for each line
update #temp_dates

from #temp_dates
inner join Shifts

--merge each temp table line with each days data for the week
