Hi,

I am planning to use a join transformation in SAS DI Studio to join two tables A and B. The relationship between A and B is one to Many. For each row in A , I would like to take only one record from B. Is there any function which allows to perform this?

Thanks in advance,

Regards,

Sheeba Swaminathan

How would you select this record from "B"? Could you use a DISTINCT or Group By in a sub-select prior to joining with A so that the relationship becomes 1:1?

tnx a lot Patrick.

Distinct keyword helped me out.

You could also use the Look-up transformation right off, that will pick only one record from the look-up table.

Is there any logic you wish to apply when choosing the B record?

tnx a lot Linush.

Any record from Table B would be a fit for join....
