Jeff,

Select d.ONRCU, d.CWSTS, h.SHPDTISO, c.DATE1
From JEFF.ORDTL d
Inner Join JEFF.ORHDR h On d.ONRCU = h.ONRCU
Inner Join JEFF.BILNGCNT c On h.SHPDTISO = c.DATE1
Where d.CWSTS In('1', '2');

Becomes

Merge Into JEFF.ORDTL as TGT
Using
(Select d.ONRCU, d.CWSTS, h.SHPDTISO, c.DATE1
From JEFF.ORDTL d
Inner Join JEFF.ORHDR h On d.ONRCU = h.ONRCU
Inner Join JEFF.BILNGCNT c On h.SHPDTISO = c.DATE1
Where d.CWSTS In('1', '2')) As SRC
On TGT.ONRCU = SRC.ONRCU
When Matched Then Set TGT.CWSTS = '3'

Subject: Need an SQL update lesson

Once again I need help with SQL, this time on an update.

This select:

Select d.ONRCU, d.CWSTS, h.SHPDTISO, c.DATE1
From JEFF.ORDTL d
Inner Join JEFF.ORHDR h On d.ONRCU = h.ONRCU
Inner Join JEFF.BILNGCNT c On h.SHPDTISO = c.DATE1
Where d.CWSTS In('1', '2');

gives me the correct records. Now I want to update field (er, column)
d.CWSTS to a literal based on this select.

I found an example that implies this should work:

Update JEFF.ORDTL Set CWSTS = '3'
From JEFF.ORDTL d
Inner Join JEFF.ORHDR h On d.ONRCU = h.ONRCU
Inner Join JEFF.BILNGCNT c On h.SHPDTISO = c.DATE1
Where d.CWSTS In('1', '2');

but it barfs at the "From" so I assume some different syntax for DB2 on the
IBM i. I feel like I'm this close, but my googling has not resulted in
other examples.

After today I'm on vacation until Tuesday, but I just gotta know . . .

Thanks.
