The problem I am having is that the system is not finding the TIMESTAMPDIFF built in function in SQL.

I don't use straight SQL much (we have SEQUEL here), but I thought that getting the parameters right might help. Some languages identify functions by name _and_ parameter list in order to support overloading.

It seems I was both wrong and right. My first suggestion does not work on my system with a "timestampdiff not found" error:
select timestampdiff(2,timestamp('2008-10-10','10:10:10')-timestamp('2008-10-09','10:10:10'))
from sysibm.sysdummy1

This however does work:
select timestampdiff(2,cast(timestamp('2008-10-10','10:10:10')-timestamp('2008-10-09','10:10:10') as char(22)))
from sysibm.sysdummy1

The example in the documentation shows that the result of the timestamp difference as to be cast to character for TIMESTAMPDIFF.

HTH,
Adam
