SQL update with a From clause

Having worked a little with MS SQL Server I've found their SQL Update with a from clause Very convenient
update fileA
set fileA.field1 = fileB.field1
from fileA inner join fileB on fileB.key = fileA.key

IMHO this syntax is much clearer then the corresponding one on DB2 for i.
Especially so when there are several files joined for the update

Use Case:

    you can use MERGE syntax for that, much more powerful.
    and standard.

    IBM does not intend to provide a solution to this request at this time, so it is being closed.

    We understand that there are many versions of SQL syntax implemented by different vendors. The UPDATE statement supported by the Db2 family of products follows the SQL standard. Investing development resources in an alternate non-standard version of update does not align with our strategy.
