Aggregated sub query inside other aggregated query - sql

Question

I use Microsoft VBA together with Excel and also use the ADODB connection to treat the Sheet as database.
I have one issue regarding a SQL aggregated query that uses also aggregated sub queries. The issue is that I cannot use it like this, due to the fact it is throwing errors and I don't know how to change it
The SQL query:
Select inv.[Region], inv.[Org Name], inv.[Bill To Customer Number], inv.[Bill To Customer Name],
SUM(inv.[AR Global Total Amount]) as "Amount Invoiced",
COUNT(pay.[Sales Invoice Number]) as "Count Invoices",
SUM(inv.[AR Global Total Amount]*(inv.[Payment Due Fiscal Date]-inv.[Invoiced Fiscal Date])) as "Sum of Terms Mult",
SUM(inv.[AR Global Total Amount]*(pay.GL_Min-inv.[Invoiced Fiscal Date])) as "Sum of Pay Days Mult",
SUM(inv.[AR Global Total Amount]*(pay.GL_Min-inv.[Payment Due Fiscal Date])) as "Sum of Days Late Mult"
FROM
(
Select *
From [Data$] as inv
WHERE [AR Transaction Sub Type] IN ('Inv', 'Inv-T')
) a,
(
Select [Region], [Org Name], [Bill To Customer Number], [Bill To Customer Name], [Sales Invoice Number], Min([GL Fiscal Date]) as GL_Min
FROM [Data$] as pay
WHERE [AR Transaction Sub Type] IN ('Cash', 'Cash-T')
GROUP BY [Region], [Org Name], [Bill To Customer Number], [Bill To Customer Name], [Sales Invoice Number]
) t
WHERE inv.[Sales Invoice Number] = pay.[Sales Invoice Number] AND inv.[Org Name] = pay.[Org Name] AND inv.[AR Global Total Amount]>0
GROUP BY inv.[Region], inv.[Org Name], inv.[Bill To Customer Number], inv.[Bill To Customer Name]
ORDER BY SUM(inv.[AR Global Total Amount]) DESC
The problem is on the second sub query, the one where I try to capture the min date.
Could someone point me to a proper syntax?
Thanks!

Answer 1

Your query seems correct except subquery alias. Could you try this?
Select inv.[Region], inv.[Org Name], inv.[Bill To Customer Number], inv.[Bill To Customer Name],
SUM(inv.[AR Global Total Amount]) as "Amount Invoiced",
COUNT(pay.[Sales Invoice Number]) as "Count Invoices",
SUM(inv.[AR Global Total Amount]*(inv.[Payment Due Fiscal Date]-inv.[Invoiced Fiscal Date])) as "Sum of Terms Mult",
SUM(inv.[AR Global Total Amount]*(pay.GL_Min-inv.[Invoiced Fiscal Date])) as "Sum of Pay Days Mult",
SUM(inv.[AR Global Total Amount]*(pay.GL_Min-inv.[Payment Due Fiscal Date])) as "Sum of Days Late Mult"
FROM
(
Select *
From [Data$] as inv
WHERE [AR Transaction Sub Type] IN ('Inv', 'Inv-T')
) inv,
(
Select [Region], [Org Name], [Bill To Customer Number], [Bill To Customer Name], [Sales Invoice Number], Min([GL Fiscal Date]) as GL_Min
FROM [Data$] as pay
WHERE [AR Transaction Sub Type] IN ('Cash', 'Cash-T')
GROUP BY [Region], [Org Name], [Bill To Customer Number], [Bill To Customer Name], [Sales Invoice Number]
) pay
WHERE inv.[Sales Invoice Number] = pay.[Sales Invoice Number] AND inv.[Org Name] = pay.[Org Name] AND inv.[AR Global Total Amount]>0
GROUP BY inv.[Region], inv.[Org Name], inv.[Bill To Customer Number], inv.[Bill To Customer Name]
ORDER BY SUM(inv.[AR Global Total Amount]) DESC
