hai all..

I am facing problem with one to many join b/w 2 hold files..

1st hold file has 1 row and 2nd has 5 matching rows.

But o/p shows me 5 rows with the only row from 1st hold file appended to all 5 rows..?!!

F1 F2 F3 F1 F2 F3

A B C A1 B C1
D B F A1 B C1
H B L A1 B C1

F1, F2 and F3 are fields and o/p comes as shown above.. (A1 B C1) is the row from 1st hold file and B is field used to join hold files..

Is there any setting for this?

Thanks all..

I'm not quite sure what setting you are looking for (or what your question really is). A one-to-many join joins a row in file a to all matching rows in file b based on a join field. That means that the info from the record in file a will show up for every record that it joins to in file b. That's the nature of one-to-many joins.

It joins like you're saying that you're not wanting that, so you need to go back an decide if you really want a one-to-many join or if you're looking for something else. If you can give us an example of what you do want, maybe we could suggest something else.

Can't I avoid (A1 B C1) from the output I have shown?

Try doing the join in the other direction, i.e. a one-to-one as the single-row file is a lookup file.

You can show whatever you want. If you don't want to see those fields, don't put them in the PRINT statement. You haven't shown us any code, so we can't tell why you're getting what you are.
