Re: SQL to validate data from multiple files

<correction>
You ------ could also do this.

SELECT IBMREQD FROM sysibm/sysdummy1
where itemisvalid('30962980') = '1'
and itemlocationisvalid('30962980','32AA00002') = '1'


Change the itemlocationisvalid to not equal to '1' for the reverse.

Sometimes is better to take the complexity out and write it separately.

Personally, I'd put each scenario in it's own SQL UDF.

this is an rpgle solution. but you'll get the point.

clear valid;
exec sql
Select '1'
into :valid
from itempf
where item = '30962980'
and itemlocationisvalid(item, '32AA00002') = '1'

If either the item is invalid or the location, then '1' will not be placed
into host variable valid.

I am trying to validate some diverse data in one pass, and am not quite
there... two elements, Part number, Inventory location.

the part number must be valid.
the location must be valid.
the combination must either not exist (when we put parts away),
or do exist (when we take parts out).

select COALESCE(VLOCPF.LLOLOC, ' ') as LLLOC,
COALESCE(ITEMPF.ITEM, ' ') as IITEM,
COALESCE(LOCPF.LITILO, ' ') as LITILO,
COALESCE( LOCPF.LITITM, ' ') as LITITM
from datalib.LOCPF as LOCPF
cross join datalib.VLOCpf as VLOCPF
cross join datalib.ITEMPF as ITEMPF
where VLOCPF.LLOLOC = '32AA00002' and
ITEMPF.ITEM = '30962980'
and (LOCPF.LITILO = '32AA00002' and LOCPF.LITITM = '30962980')

This works for my first two files, but when I add the 3rd validation
(the combination of part location), I do not return ANY data...
