AS400 SQL update with multiple files

I would like to update fields on one file based on a join between it and an another file.  I keep getting error on my varies attempt.  (from not expected)

One example:

update cempmst set emp1='000000',amt=0  
from cempmst a, cnewemp b              
where  nwcemp=emp                      

Thank You.

FROM clause is not allowed on an UPDATE.  Can you explain what you are trying to do?  Looks like you want to zero out the emp1 and amt fields for all employees in the "new employee" table.  If so:

update cempmst
set emp1='000000', amt=0
where emp in (select nwcemp from cnewemp)
