Retrieve last row Value from Access Table

[Siyanna]

Hi All

I have a table called Log which gets updated when something gets updated

What i want to be able from the Column called Version - i want to retrieve the last row value in that column

say it says V8

i want to on workbook open check to see if the value matches the cell value on sheet2!A1 - if it does then fine but if it doesnt then close the workbook saying not in latest version

hoping you can help me

The order of records really has no meaning in Access tables (someone once described it as a bag of jumbled marbles).
You can do an Aggregate Query, to return a record with the oldest/newest date or maximum/minimum value.
So, is there some field you can use to determine exactly which record you want to return? Maybe some sort of date field?

Thank you for that explanation

i didnt have a value to sum but i managed to get the value by ordering it by version number and then selected top 1 from that column

maybe if it has a date column and you know a little vba then do a select query order by date and do a recordset.movelast

Aggregate Queries are used for more than just summing!

I was thinking you could use First/Last or Min/Max on some field.

The query might look something like this:

SELECT *
FROM MyTable
WHERE Version_Number = 
(SELECT Max(MyTable.Version_Number)
FROM MyTable);

maybe if it has a date column and you know a little vba then do a select query order by date and do a recordset.movelast

You *could* do it this way, but VBA/Recordsets seems to be a bit overkill and unnecessary here. You would still need to Sort/Order the records first, and if you can do that, you can simply use that field in an Aggregate Query instead.

If you have an autonumber or date field then you could also combine Dmax with Dlookup to get the true last. If there is no additions or deletions then DLast will get the last entry.
