Создание 1 записи в 1 таблице из нескольких записей в другой таблице

Question

Я пытаюсь заполнить таблицу несколькими записями из другой таблицы.У меня есть таблица, которая содержит записи о графике работника.Каждая запись содержит один инцидент с датой и временем для 1 сотрудника: поля:

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

Мне нужно преобразовать это, чтобы оно выглядело как сетка расписания в приложении и в отчетах.Это 1 строка в сетке = до 7 предыдущих записей (понедельник - воскресенье)

Пример входных данных: ScheduleName ScheduleBeginDay ShiftName ScheduleStart ScheduleEnd Position ADP_ID ScheduleLine Walk-In Center Апрель Wk 1 2019 понедельник 1-я смена 2019-04-01 07: 00: 00.000 2019-04-01 15: 30: 00.000 Mental Health Tech 10391 1 Проходной центр Апрель Wk 1 2019 Понедельник 1-я Смена 2019-04-02 07: 00: 00.000 2019-04-0215: 30: 00.000 Mental Health Tech 10391 1 Walk-In Center April Wk 1 2019 Понедельник 1st Shift 2019-04-03 07: 00: 00.000 2019-04-03 15: 30: 00.000 Mental Health Tech 10391 1 Walk-InАпрель Wk 1 2019 Понедельник 1-я смена 2019-04-04 07: 00: 00.000 2019-04-04 15: 30: 00.000 Mental Health Tech 10391 1 Вступительный центр Апрель Wk 1 2019 Понедельник 1-я смена 2019-04-05 07:00: 00.000 2019-04-05 15: 30: 00.000 Mental Health Tech 10391 1 Walk-In Center April Wk 1 2019 Понедельник 1-я смена 2019-04-06 07: 00: 00.000 2019-04-06 15: 30: 00.000 MentalHealth Tech 10244 1

Код ниже работает, но ТОЛЬКО если есть человекв позиции в первый день. Это обычно, но не всегда.вопрос «Как создать 1 строку вывода для каждой строки (позиции) в расписании (при условии, что хотя бы один человек работает хотя бы один день на этой должности хотя бы один день в течение недели)?

Этот код работает для создания еженедельного расписания из отдельных записей.В реальном коде реального времени жестко запрограммированные строки (имя расписания, дата начала) будут фактически заполняться из полей на экране или вычисляемых полей

--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
set ScheduleStart = @startdate + cast(Shifts.WorkTimeStart as datetime) , ScheduleEnd     = @startdate + cast(Shifts.WorkTimeEnd as datetime)
from #temp_dates
inner join Shifts
on shifts.ShiftName = #temp_dates.shiftname

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