Angry displaying unique records....
hello all.
thanks in advance for any help provided.

I have an access db with 3 fields.
Id, TitleName and LinkName.

Info in the db is like..

id TitleName LinkName
-----------------------------
1 Jack Link1
2 Jack Link2
3 Bob Link1
4 Bob Link2
5 Bob Link3


What i want to display..

id TitleName LinkName
-----------------------------
1 Jack Link1
3 Bob Link1

I've tried using DISTINCT with no luck. I realize I can't use distinct on a unique cloumn like ID.

any ideas?

Maybe I could count the records and filter any 'where Count(titleName) < 2' ?

doh, if I had any hair I would pull it out.

many thanks.
f00l

If that is the way your table is setup, you can't get that information in a single query.
Instead of having it like this (which violates Normal Form rules of database creation, because you have duplicate data withing a table)
Quote:
id TitleName LinkName
-----------------------------
1 Jack Link1
2 Jack Link2
3 Bob Link1
4 Bob Link2
5 Bob Link3

Why don't you set it up like this
Code:
id    Titlename      LinkName1      LinkName2      LinkName3
1      Jack          Link1          Link2
2      Bob           Link1          Link2          Link3

This way you don't have duplicated data.

thanks but....
the LinkName column is NOT unique info.

i used link1, link2 as an example as I will be sorting by TitleName, LinkName ASC

If I were to convert the DB to your described methed, would I not be at the same place I am now?

In your new db layout, how would I extract all records without duplicate TitleNames and still have access to the ID and LinkName columns?

thanks!

you could iterate thru the returned recordset & compare titlename with the previous records titlename & ignore if the same.
