SQL problem

Hi

Hopefully someone can help with the following. The SQL statement
below works correctly, selecting the maximum [completion date] for
each store (there will be several records for each store in the
InvestmentHistory table.

SELECT InvestmentHistory.[Store ID], Max(InvestmentHistory.[Completion
Date]) AS [MaxOfCompletion Date]
FROM InvestmentHistory
GROUP BY InvestmentHistory.[Store ID];

However, i also want to select 2 other columns from the table:
[ProjectName] and [InvestmentType]. When i add these two columns in to
get:

SELECT InvestmentHistory.[Store ID], Max(InvestmentHistory.[Completion
Date]) AS [MaxOfCompletion Date], InvestmentHistory.[Investment Type],
InvestmentHistory.ProjectName
FROM InvestmentHistory
GROUP BY InvestmentHistory.[Store ID], InvestmentHistory.[Investment
Type], InvestmentHistory.ProjectName;

the query returns all the data again, presumably because there are
different values in the other 2 columns. Basically i just want the
query to return the info related to the maximum completiton date for
each store.

any ideas how i can achieve this.
Thanks for any suggestions.

I didn't test this, but it should work.

SELECT B.[Store ID], A.[ProjectName], A.[InvestmentType], B.[MaxDate]
FROM InvestmentHistory AS A
INNER JOIN
(SELECT [Store ID], Max([Completion
Date]) AS [MaxDate]
FROM InvestmentHistory
GROUP BY [Store ID]) AS B
ON A.[Store ID] = B.[Store ID] AND
A.[Completion Date] = B.[MaxDate]
