RE: Create a field in AS/400 queries

Hi,

I'm tried to concatenate but I'm not able because it's numbers. It
returns an error saying that the concatenation is not allowed with the
operand sign



Obrigado,
Marco Silva

Marco,

This can be quite easily done in Query/400. However, I recommend you
create a "view" that does this. This will prevent you from having to
put
this logic into every query that uses this combo.

Let's say I have a table that has these fields: myear, mmonth, mday
(among
others).

If I do the following:
create view qtemp/marcol1 as (
select date(digits(myear) concat '-' concat
digits(mmonth) concat '-' concat
digits(mday)) as RealDate,
a.*
from qtemp/marco a)

I can now query this view, or logical file, in Query:
select *
from qtemp/marcol1
....+....1....+....2....+....3..
REALDATE MYEAR MMONTH MDAY
2006-05-01 2,006 5 1
******** End of data ********

This will save you from putting all that logic in every Query.

Again it is now a true date field:
select days(current date) - days(realdate) as AgingDays,
marcol1.*
from qtemp/marcol1
+....1....+....2....+....3....+....4....+...
AGINGDAYS REALDATE MYEAR MMONTH MDAY
497 2006-05-01 2,006 5 1
**** End of data ********
