I'm using Access via OleDb. I have a table with columns ID, GroupID, Time and Place. An application inserts new records into the table, unfortunately the Place isn't calculated correctly.
I want to update each record in a group with its correct place according to its time ascending.
So assume the following data:
ID GroupId Time Place
Chuck 1 10:01 2
Alice 1 09:01 3
Bob 1 09:31 1
should result in:
ID GroupId Time Place
Chuck 1 10:01 3
Alice 1 09:01 1
Bob 1 09:31 2
I could come up with a solution using a cursor but that's AFAIK not possible in Access.
I just did a search on performing "ranking in Access" and I got this support.microsoft result.
It seems you create a query with a field that has the following expression:
Place: (Select Count(*) from table1 Where [Time] < [table1alias].[Time]) + 1
I can't test this, so I hope it works.
Using this you may be able to do (where queryAbove
is the above query):
UPDATE table1
SET [Place] = queryAbove.[Place]
FROM queryAbove
WHERE table1.ID = queryAbove.ID
It's a long shot but please give it a go.
