Select the first row in a join of two tables in one statement

Question

I need to select only the first row from a query that joins tables A and B. On table B exist multiple records with same name. There are not identifiers in any of the two tab

Answer 1

If you can add to a temp table and then query from that, you can do it in one go.

WITH T AS (temp table select), RN AS (select min row-numbers from T) SELECT T.NAME, T.DATA1, T.DATA2 FROM T INNER JOIN RN on T.row_number = RN.row_number

There are many other ways to write this, but that's how I've been doing similar things.
