Hi Jon,

1. Update from an other table:
UPDATE TableA a
SET (a.Field1,
a.Field2, ... ,
a.FieldN) = (SELECT b.Field1, b.Field2, ... , FieldN
FROM TableB b
WHERE a.Key1 = b.Key1
and a.Key2 = b.Key2)
WHERE EXISTS (SELECT 1 FROM TableB c
WHERE a.Key1 = c.Key2
a.Key1 = c.Key2)

2. Insert from an other table
Insert into TableB
(Field1, Field2, ... , FieldN)
Select Field1, Field2, ... , FieldN
from TableA a exception join TableB b
on a.Key1 = b.Key1
and a.Key2 = b.Key2

These SQL statements are not checked, because I currently have no access to
an iSeries.

Mit freundlichen Grüßen / Best regards

Betreff: SQL Gurus Wanted


Can any of the SQL gurus out there suggest the magic incantation's) that
will achieve the following.

Tables A and B have a number of common columns.

If the keys in A and B match, update columns in A with the values from B.

If there is a row in B that does not exist in A, then insert a new row based
on B.

It is late on Sunday (actually early Monday) and my brain has seized.
