MS Access - Query - return 2 records for each

I need to return only 2 records for EACH [ExpenseAccount] in @groupedStrings from [Source_Data].  [Source_Data] has thousands of matches for each value in @groupedStrings

The query I have below returns all.  I only want 2 records for each.  How do I do that?


SELECT [@groupedStrings].ExpenseAccount, Source_Data.AssetNumber
FROM ([@groupedStrings] INNER JOIN ExpenseAccount_RAMBO ON [@groupedStrings].ExpenseAccount = ExpenseAccount_RAMBO.[Payable Expense Number]) INNER JOIN Source_Data ON ExpenseAccount_RAMBO.lessor = Source_Data.LessorCode;

SELECT TOP 2 [@groupedStrings].ExpenseAccount, Source_Data.AssetNumber
FROM ([@groupedStrings] INNER JOIN ExpenseAccount_RAMBO ON [@groupedStrings].ExpenseAccount = ExpenseAccount_RAMBO.[Payable Expense Number]) INNER JOIN Source_Data ON ExpenseAccount_RAMBO.lessor = Source_Data.LessorCode;

That only returns 2 records TOTAL.  I need 2 records from the joined table [Source_Data] for EACH matching record in @groupedStrings
keschusterAuthor Commented:

Active Protection takes the fight to cryptojacking

While there were several headline-grabbing ransomware attacks during in 2017, another big threat started appearing at the same time that didn’t get the same coverage – illicit cryptomining.

among the numerous records of 1 's (for example)  what criteria are applied to get the two records?
keschusterAuthor Commented:
Let me better illustrate

The more I think about it my original stab at the sql may be too complicated.

The table looks like this

ExpenseAccount     | VIN
1                             | 10
1                             | 11
1                             | 12
2                             | 20
2                             | 21
2                             |22


So for a single ExpenseAccount there can be many VIN's.  Vins are unique

What I want to return is for each unique ExpenseAccount any 2 Vins
Rey Obrero (Capricorn1)Commented:
where is the field VIN coming from?

better if you can upload a sample db..

try this query

SELECT tblFeed_Rambo.ExpenseAccount, Max(tblFeed_Rambo.VIN) AS MaxOfVIN
FROM tblFeed_Rambo
GROUP BY tblFeed_Rambo.ExpenseAccount
Union ALL
SELECT tblFeed_Rambo.ExpenseAccount, Min(tblFeed_Rambo.VIN) AS MaxOfVIN
FROM tblFeed_Rambo
GROUP BY tblFeed_Rambo.ExpenseAccount
Order By 1
