Re: Ok, I need an alternative SQL syntax

Doesn't seem like that should work as the outside construct is an insert,
and the prepared statements allowed are select. I will try though.

Switch to dynamic...thus allowing the use of a variable with FETCH FIRST?

Here is what I need:

insert into qtemp/wk_jcpordf (relid, relsq, uid)
select :relid, :relsq, a.iduid
from jcuidp a
join (select distinct idjyr, idjno, idbpth
from jcuidp
where iduid = :uid
and idstat = 'A') b
on (a.idjyr, a.idjno, a.idbpth) =
(b.idjyr, b.idjno, b.idbpth)
left exception join jcpordf c
on c.dpuid = a.iduid and c.pstat = 'A'
fetch first :qty rows only;


JCUIDP contains a map of serial numbers (iduid) with a reference to it's
location in a bill of materials (idbpth) for a job (idjyr, idjno). If a
part has a quantity of 5 at a particular location in the BOM, there will

be

5 JCUIDF records with a unique serial number for each of the 5 parts.

JCPORF is a list of parts by UID that have been released for purchasing.

At any time, a partial quantity of the parts for a location in the BOM

can

be released for purchasing. If I want to release 2 of these 5 parts, I

want

to set qty = 2, and run this insert. This would insert two unreleased
serial numbers into the wk_ file. I can get the select to work with a
constant value, but not a variable. Unfortunately, the user needs to be
able to pick the quantity so it can't be a constant. I see the following
note in the SQL Reference:

Allowed use of variable: fetch-first-row-count can be specified as a
variable only as part of the outer fullselect of a DECLARE CURSOR

statement

or a prepared select-statement.

So :qty can not be specified here in this insert. I need logic to get
around this limitation. I can do it in RLA, but the logic is complex,

and I

prefer to keep it in SQL. Any ideas?
