Hi all. I have two tables in access (VB6): SupplierInvoices & Sales. They both have 3 common field names: Date, Code & Qty. I need to query both tables via SQL query by a specific date range as follows (I know this is wrong, but just to give you an idea):
rs.Open "Select distinct format(SupplierInvoices.Date, 'dd-MMM-yyyy') as tDate, Sum(SupplierInvoices.QTY) as tTotal from SupplierInvoices, format(Sales.Date, 'dd-MMM-yyyy') as sDate, Sum(Sales.QTY) as sTotal from Sales where PLU = '" & lblPLU.Caption & "' and Date Between #" & StartTime & "# and #" & EndTime & "# Group by format(SupplierInvoices.Date, 'dd-MMM-yyyy');", cn, adOpenKeyset, adLockOptimistic
The result needs to return from both tables the sum of the qty fields for that date range. I can't get it right! Please help.

I don't have any experience with Access, but from what I know from SQL server, I think when you have group by you are allowed to have in the select the aggregate and the group by field. The problem is that you have a group by from one of the tables and put other fields in the select. I think you have to use Union and get it in separate set of rows. And from that set you can try to select in an outer select. Not sure if this is possible in Access.

I have tried this but get Group by error:
rs2.Open "Select distinct format(SupplierInvoices.Date, 'dd-MMM-yyyy') as tDate, Sum(SupplierInvoices.QTY) as lTotal from SupplierInvoices where PLU = '" & lblPLU.Caption & "' and Date Between #" & StartTime & "# and #" & EndTime & "# Union Select distinct format(Sales.Date, 'dd-MMM-yyyy') as tDate, Sum(Sales.QTY) as sTotal from Sales where PLU = '" & lblPLU.Caption & "' and Date Between #" & StartTime & "# and #" & EndTime & "#;", cn, adOpenKeyset, adLockOptimistic

I mean something like:
select SupplierInvoices.Date as tDate, Sum(SupplierInvoices.QTY) as lTotal, 'supplier' as tablename
group by tdate,tablename
Union
select other table same thing
I can't test it, but I would try something like that

Thank you my good man. I am almost there!!! except I get an error saying item rs2!sTotal cannot be found:
rs2.Open "Select distinct format(SupplierInvoices.Date, 'dd-MMM-yyyy') as tDate, Sum(SupplierInvoices.QTY) as lTotal from SupplierInvoices where PLU = '" & lblPLU.Caption & "' and Date Between #" & StartTime & "# and #" & EndTime & "# Group by format(SupplierInvoices.Date, 'dd-MMM-yyyy') Union Select distinct format(Sales.Date, 'dd-MMM-yyyy') as tDate, Sum(Sales.QTY) as sTotal from Sales where PLU = '" & lblPLU.Caption & "' and Date Between #" & StartTime & "# and #" & EndTime & "# Group by format(Sales.Date, 'dd-MMM-yyyy');", cn, adOpenKeyset, adLockOptimistic

The error you are getting is because in Union the column names have to be the same. That's why you need another column tablename to distinguish between them
I would also try to put in the first original query
Select distinct format(SupplierInvoices.Date, 'dd-MMM-yyyy') as tDate, Sum(SupplierInvoices.QTY) as tTotal from SupplierInvoices, format(Sales.Date, 'dd-MMM-yyyy') as sDate, Sum(Sales.QTY) as sTotal from Sales where PLU = '" & lblPLU.Caption & "' and Date Between #" & StartTime & "# and #" & EndTime & "# Group by tDate, sDate
Wouldn't that work too?

I also tried:
rs2.Open "Select distinct format(SupplierInvoices.Date, 'dd-MMM-yyyy') as tDate, Sum(SupplierInvoices.QTY) as tTotal, format(Sales.Date, 'dd-MMM-yyyy') as sDate, Sum(Sales.QTY) as sTotal from SupplierInvoices, Sales where PLU = '" & lblPLU.Caption & "' and Date Between #" & StartTime & "# and #" & EndTime & "# Group by tDate, sDate;", cn, adOpenKeyset, adLockOptimistic
but it says "the field PLU could refer to more than one...."

I am using a SSD to hold code and (until Sunday) databases that were attached to the sql instance on my desktop and my laptop. Everything was fine until Sunday night, when I think I did some steps in the wrong order on my desktop regarding detaching/attaching databases. In the process of doing something wrong, I lost all of the database work I had done over the weekend. Half a dozen tables and almost a dozen stored procs - gone - and could not be recovered.
Today, I finished reinventing all the database crap I lost, and implemented a new policy. I create two jobs - one that backs up all the databases (that are not system databases) to the SSD, and one that restores the backed up databases from the SSD. Now all I have to do is remember to run them (and not run the wrong one when I run one).
BTW, my template project is going quite well, and I'm almost ready to make the demo video (hopefully by sometime next week.

Won't do the job. You have to use ssms or sql server to backup/restore databases. I'll only be using this as a synchronization vehicle.

Losing work always sucks,  but I usually find that the second effort is better than the original. The bonus is the lesson you learned and steps taken to keep it from reoccurring. Sometimes it pays dividends to idiot-proof your own stuff!

I agree - it sucks, but the second is one is usually better than the first.
Accept that one time that I lost a new algorithm and could not recreate the thought process that allowed me to create it in the first place. It was beautiful, it was inspired, efficient and now gone forever.

Well I’m having issues with my reinvention. I feel like I have to say one more time that I hate EF6...
EDIT ===============
It's Friday morning - the afore mentioned issues have been resolved. I am now back to a functioning website and database, and I can finally say that I'm back to where I was on Sunday before I screwed up.
Final observations - EF6 sucks. In point of fact, I'm gonna go out on a limb and claim that ALL ORMs suck.

Can't be a scheduled task. It can't even be a startup task due to the nature of "the way things are" regarding the SSD. I'm sure reading my explanation would take a lot more time than you are willing to invest in reading it.
