check out the JOIN option

SELECT single F_{plnnr p}STATU

INTO (t1, t2)

FROM AFKO AS F INNER JOIN PLKO AS P

ON F_{plnnr = P}plnnr

WHERE AUFNR = '007200000100'.

data: statu type plko-statu.



select single statu into statu
       from afko
          inner join plko
             on afko~plnnr = plko~plnnr
                      where aufnr = '007200000100'.

oops....

sorry u cant use select single in a sub query

the syntax of a subquery is quite restricted...the link will give you the details...

but in any case....either u use joins or subqueries...i dont think there will be a major impact on performance in this particular case that you have specified.

using subqueries it is possible

select single statu from plko into t2 where plnnr in (select single plnnr from afko where aufnr eq '007200000100').

read about subqueries at this link...
