also, consider this:

update fileA
set fileA.field1 = fileB.field1,
fileA.field2 = fileC.field2,
fileA.field3 = fileD.field3
from fileA inner join fileB on fileB.key = fileA.key
inner join fileC on fileC.key = fileA.key
inner join fileD on fileD.key = fileA.key

achieving this with our DB2 method is exponentially more complex


No it isn't...use MERGE.
