Consolidating Records (1 Viewer)

[HeelNGville]

I have a table that contains specific customer transaction data. In this table there are the following fields:

Document
Vendor
Vendor Name
Units
Value

There are instances in which multiple records could exist for one document number. Such as:

Document-----Vendor-------Vendor Name------Units------Value--------
12345678------AAAA--------ABC Co.-------100------200.00
12345678------BBBB---------BBC Co.--------25-------50.00
12345678------CCCC----------CCC Co.--------10-------20.00

What I am attempting to do is, sum the units & value fields and report the data on one line with the vendor record with the > unit count. So, for the example above, the data returned would be:

Document-----Vendor-------Vendor Name------Units------Value--------
12345678------AAAA--------ABC Co.-------135------270.00

Can this be performed in one single query vs multiple queries. If so, any guidance would be welcomed.
Thx

If you are using Access 2K or later versions, you can run a query that joins the table to a subselect statement in brackets like this:-

SELECT ss.Document, [TableName].Vendor, [TableName].[Vendor Name], ss.SumOfUnits AS Units, ss.SumOfValue AS [Value]
FROM (SELECT [TableName].Document, Max([TableName].Units) AS MaxOfUnits, Sum([TableName].Units) AS SumOfUnits, Sum([TableName].Value) AS SumOfValue
FROM [TableName]
GROUP BY [TableName].Document) AS ss INNER JOIN TableName ON (ss.MaxOfUnits = [TableName].Units) AND (ss.Document = [TableName].Document);


But when the query is saved, Access may change the brackets surrounding the subselect to a pair of square brackets with an ending dot.

SELECT ss.Document, [TableName].Vendor, [TableName].[Vendor Name], ss.SumOfUnits AS Units, ss.SumOfValue AS [Value]
FROM [SELECT [TableName].Document, Max([TableName].Units) AS MaxOfUnits, Sum([TableName].Units) AS SumOfUnits, Sum([TableName].Value) AS SumOfValue
FROM [TableName]
GROUP BY [TableName].Document]. AS ss INNER JOIN TableName ON (ss.Document = [TableName].Document) AND (ss.MaxOfUnits = [TableName].Units);

Hence, if you subsequently edit the query, you may need to change [...]. back to (...)


If you use two queries instead of a single query, you don't have such a problem in editing.

I have attached a database in Access 2K, which contains both methods.
