Hi Graham

Please don't think I'm rude if I don't reply to anything you send but I'm going to bed now!
I will have a look tomorrow with great interest to see if you have come up with anything.

much appreciated

Phil

Oh, and one other question – do you have a separate Accounts table with [account no] as the primary key?

Hi Phil

This is quite a tricky query. Could you please clarify a couple of things?

1. If one or more of the five most recent bets for a particular account is of a category which is NOT "core=yes", then that account should be excluded. Is this correct?

2. Should an account be included if it has fewer than five bets in total, but all of them are "core=yes" categories?

3. Is it possible for an account to have two bets with exactly the same value for [date placed]

4. If so, and the fifth-equal-to-last bets are of different categories, one core and one non-core, should that account be included?

5. Is core a boolean (yes/no) field?

6. What is the name of the primary key field in the Categories table?

Well, that was more than a couple of questions, but we're not very good at counting down here in New Zealand ;-)

Cheers,

Graham

Hi Bill

thanks for your prompt reply.

i'm still not getting it.

I create my queries using design view and don't seem to be able to do this in that view (or can I?) but I have changed to sql view to add this TOP function to no avail - it is returning 5 records but not in the way I am looking for.

It is a bit more complicated than I first described - there are 2 tables and the field that I am testing for 5 occurances in the last 5 records of the 1st table is in the 2nd table

Table 1 - Bets has the following relevant fields date placed, account no, category
Table 2 - Categories is linked by the field category and has a relevant field called core

I want to a list of accounts where the last 5 bets (by date placed) have had a category which has core=yes

so i don't necessarily want the detail of the last 5 records which fulfil the criteria - I just want to know the account nos

Is the TOP function still what I need to achieve this?

Sorry I wasn't clear enough before - am I this time ??!!

cheers

Phil

Easy-squeezy!
SELECT TOP 5 *
FROM MyTable
WHERE Color = "Green"
ORDER BY SalesDate DESC

DESC means decending or reverse order. The TOP operator returns the stated number of records. You can also use TOP 5% if you want a percentage of records.
