Fill in some projektzuteilung.dauer and some more projektzuteilung.startzeit
Currently, all projektzuteilung.dauer
are NULL
. Change them to actual values for at least some of the entries (maybe around half of them), so that queries using that attribute give meaningful results.
Also fill in some more projektzuteilung.startzeit
values. (Currently, only one entry has a non-NULL
one.)
(What are the semantics of these fields, anyway?)
