Hello All,

I am getting the following error when using an aggregate function in the update statement.

UPDATE  table1
FROM    table2
SET     val = SUM(table2.val)
WHERE
        table1.field = table2.field

3872 Illegal use of an aggregate operation in an UPDATE statement.

Generated By: OPT modules.

For Whom: End User.

Remedy: Correct the request and resubmit the


In Oracle, I was using the following statement to achieve the same

UPDATE table1
SET val = (SELECT SUM(val) FROM table2 where table2.field_name = table1.field_name)

Please let me know correct way to write the SQL to get the final result.
