RE: SQL question on join and limit rows retrieved

["Porterfield, Sean" <SPorterfield@xxxxxxxxxxxxxxxxxxxxxxx>]

Fantastic!  I'll have to check performance tomorrow, but I'm at least getting results now.

I added a comma after fldb below and made the "join" table name match the "with" table name.  Other than that, it was an easy conversion to my files and fields.

With tmpDetail as (
   select keyfld, flda, fldb
   row_number() over(partition by keyfld) RowByKey
  from detail
)
Select * from header a
join detail b
 on a.keyfld = b.keyfld
and b.RowByKey = 1



Use a key field from the file to start the row number over.
