Question

I have a query which appears to be working fine, but I’m wondering if there is a cleaner (or more proper) way to write it.

The goal is to find the record in table ZVBAPIUSW01 where the date (UPDPASS) and time (UPDPASSTIME) are the greatest based on a given user ID.

Here is what I have got so far:

SELECT SINGLE * FROM ZVBAPIUSW01
  WHERE OBJID = ID
  AND UPDPASS IN (
    SELECT MAX( UPDPASS ) FROM ZVBAPIUSW01 WHERE OBJID = ID )
  AND UPDPASSTIME IN (
    SELECT MAX( UPDPASSTIME ) FROM ZVBAPIUSW01 WHERE OBJID = ID AND UPDPASS IN (
      SELECT MAX( UPDPASS ) FROM ZVBAPIUSW01 WHERE OBJID = ID ) ).

Thanks for your help.

You could try

SELECT foo bar baz
  FROM ZVBAPIUSW01 UP TO 1 ROWS
  INTO (l_foo, l_bar, l_baz)
  WHERE OBJID = ID
  ORDER BY updpass DESCENDING updpasstime DESCENDING.
