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;

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
