Does this work?
select *
from t1
join t2 on (t1.datum = t2.sdat or dayname(t1.datum) = t2.tag);

Hi listers

Hi Travis
Thank you for the hint.
i yesterday found the following hint, which I then followed.
select t1.datum, t2.sdat. t3.tag from table as t1
left outer join table2 as t2 on t1.datum = t2.sdat
left outer join table2 as t3 on dayname(t1.datum) = t3.tag
Note: it does not work with inner
