RE: turn a select into an update (with multiple joins)

I'd replace each of the join files with an EXISTS clause. Since you used the simple join syntax, we treat that as an inner join type, which can be determined via the exists clause.

Update tfactlib/FLROUTG
Set FLWORKC = 9155
Where FLWORKC = 3155
and ILDDM1 >= .25
and BOMDATEF < 20120305 and BOMDATDS > 20120305
and EXISTS (Select * from tfactalib/BOMMSTR
where BOMPARNT = FLPRODNO)
and EXISTS (Select * from tfactlib/ildpf
where BOMCHILD = ILDINO)

Subject: turn a select into an update (with multiple joins)

The following SQL returns the list of records I want to update:

select FLWORKC, FLPRODNO, BOMCHILD
from tfactlib/FLROUTG
join tfactalib/BOMMSTR on BOMPARNT = FLPRODNO
join tfactlib/ildpf on BOMCHILD = ILDINO
where FLWORKC = 3155
and ILDDM1 >= .25
and BOMDATEF < 20120305 and BOMDATDS > 20120305


I want to "SET FLWORKC = 9155"
