Case statement?

I have a curiosity question that hopefully might also teach me
more about SQL set-based processing. We added a foreign key to an
existing table. To initialize the new column, we ran the following two
updated statements. My question is whether there is a way to do this as a
single update set -- rather than processing the table twice?


Update SOOSH01T
Set SOWFSTSTID = (Select SOWFSTSTID from SOWFSTST
Where WRKFLWCDE = 'DELIVERED')
Where SOOSH01TID in (Select SOOSH01TID from SOOSH00V03
Where SHPSTSCDE = 'Closed');

Update SOOSH01T
Set SOWFSTSTID = (Select SOWFSTSTID from SOWFSTST
Where WRKFLWCDE = 'WAREHOUSEREADY')
Where SOOSH01TID in (Select SOOSH01TID from SOOSH00V03
Where SHPSTSCDE <> 'Closed');


Sincerely,

Dave Clark
