I tried this, but it didn't worked out.
This is my table:
ordnr, brpr, magnr,date,
The table contains orders, the ordnr contains the number of the order but it
is not unique because an order consists out of more then one line, the total
amount of the order is calculated and put in the first occurance (thus the
first line) of an order with a specific number.
eg: ordernumber 123 consists of 3 records like this:
123 125 1 01/01/2001 (*)
123 100 1 01/01/2001
123 25 1 01/01/2001
I want only the first occurance of that records out of my database in this
case the * row. We tried everything with distinct and other possibilities but
I'm afraid this isn't possible, or is it ?
thanx

You could use GROUP BY. (A bit heavy-handed, but hey, it works!)
SELECT
Column1
, Column2
, Column3
, Column4
FROM MyTable
WHERE (Criteria here)
GROUP BY
Column1
, Column2
, Column3
, Column4
If Column4 has multiple entries (all others being the same) there will be only 1 row in the resultset. The same goes for any combinations, starting from the rightmost listed column, where the columns have duplicate values.
This should work, and there may be other suggestions coming

Hi,
I've got something, but I can't get all of my columns shown. I've got a
table with a few columns and in one columns there are records with duplicate
values, so I use a distinct to get all the duplicates out of the result set,
but this only works for 1 column, I also want to show the other columns of
that record that was filtered by the distinct clause, but this doesn't work.
Any suggestions?
thanks
