Re: Need an SQL update lesson

Old thread. It has been 7 months and we are finally at a point of moving
on this.

First off, Vern's suggestion of this:

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

did indeed work. Now I want to do this:

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

to make sure the line item and the order are both active. No joy. I get
this error:

SQL State: 42703
Vendor Code: -206
Message: [SQL0206] Column or global variable ACREC not found. Cause . . . .
. : ACREC was not found as a column of table *N in *N and was not found
as a global variable in *N. If the table is *N, ACREC is not a column of
any table or view that can be referenced, or ACREC is a special register
that cannot be set in an atomic compound statement. Recovery . . . : Do
one of the following and try the request again: -- Ensure that the column
and table names are specified correctly in the statement. -- If this is a
SELECT statement, ensure that all the required tables were named in the
FROM clause. -- If the column was intended to be a correlated reference,
qualify the column with the correct table designator. -- If the column was
intended to be a global variable, qualify the name with the schema where
the global variable exists or ensure the schema is in the path. -- If this
is a SET statement for a special register within an atomic compound dynamic
statement, remove the statement or remove the ATOMIC keyword.

It's barfing on the h.ACREC reference. The field does exist in that file.
What am I doing that is not allowed?

Thanks.

I think Vern's worked. Further testing after vacation.

Thanks all. This list is so great.

Jeff,

Select d.ONRCU, d.CWSTS, h.SHPDTISO, c.DATE1

Inner Join JEFF.BILNGCNT c On h.SHPDTISO = c.DATE1

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.
