Answer 1

Hi if this has not been solved yet. To get the last record for any field from a table the easiest way would be to add an ID to each record say pID. Also say that in your table you would like to hhet the last record for each 'Name', run the simple query

SELECT Name, MAX(pID) as LastID
INTO [TableName]
FROM [YourTableName]
GROUP BY [Name]/[Any other field you would like your last records to appear by]    

You should now have a table containing the Names in one column and the last available ID for that Name. Now you can use a join to get the other details from your primary table, say this is some price or date then run the following:

SELECT a.*,b.Price/b.date/b.[Whatever other field you want]
FROM [TableName] a LEFT JOIN [YourTableName] 
ON a.Name = b.Name and a.LastID = b.pID

This should then give you the last records for each Name, for the first record run the same queries as above just replace the Max by Min above.

This should be easy to follow and should run quicker as well
