I need assistance in wirting this sql statement from 4 tables, and not sure how to write it. I have the below example...Any help will be greatly appreciated...thx


Table1                          Table2                             Table3                    Table4
JobDate                        JobDate                            JobDate                  JobDate
JobNumber                  JobNumber                      JobNumber            JobNumber
EquipSubtotal              LaborSubTotal                   SuppliesTotal         MiscExpenseSubTotal
                                    HotelSubtotal

Input Variables:    @JobNumber, @StartDate, @EndDate

Here is 4 Tables. The end result I am looking for:
Selected JobNumber:
Day 1
EquipmentTotal        LaborTotal      HotelTotal      SuppliesTotal   MiscExpenseTotal
Day2
Equipment Total     LaborTotal      HotelTotal      SuppliesTotal   MiscExpenseTotal
etc...

Table1 contains multiple entries for each day for each piece of equipment(Subtotal), but I only want the Sum(EquipSubtotal) as equipmentTotal returned for that day.

Table2 contains multiple rows for each day for Hotel and Labor, but only need the Sum(HotelSubtotal) and Sum(LaborSubTotal ) returned for each day

Table3 contains only 1 row of the sum of the supplies total for each day, there is no multiple entries for each day, just once per day and the total.

Table4 contains multiple rows for each day for mis expenses. I need to only return the Sum(MiscExpenseSubTotal) for that day.

There may not be a anything for that day in 1 of the tables, but I need the other tables to be returned in the query. All Tables have a default of $0.00 so there is no Nulls.

SELECT t.jobdate, sum(t.EquipSubTotal) sub, sum(LaborSubTotal) lab FROM
(
select jobdate, EquipSubTotal, 0 as LaborSubTotal, 0 as HotelSubtotal, 0 as SuppliesTotal , 0 as MiscExpenseTotal FROM table1
UNION ALL
select jobdate, 0 as EquipSubTotal, LaborSubTotal, HotelSubtotal, 0 as SuppliesTotal , 0 as MiscExpenseTotal FROM table2
) AS t
GROUP BY T.jobdate

something like the above, but with all the tables in, all the fields and the right rows selected

I am getting how you are creating this table, as I am writing this out, but should the first line be  Select t.jobdate, sum(EquipSubTotal) sub, .........insteasd of sum(t.EquipSubTotal).....?
or should it be sum(t.laborSubTotal) in the first line?

I'm trying, I really am. But I've seen so many wrong approaches involving date(time) boundaries I despair about my inability to explain it. I've seen quite a few recently that define a non-leap year as 364 days, or 366 days and the list goes on. …
