Re: Would it be possible to Join two physical tables with mismatching data types and attributes and CCSID s?

The field length is 20, the buffer length 40.

Note: The buffer length of 20 should not be confused with how many
_characters_ the field has. The fields have equivalent characters in
length, thus no Substring should be done.

Scenario:
chgjob ccsid(37)
strsql
create table qtemp.p1 (Z numeric (10, 0) not null )
create table qtemp.p2 (G graphic (10) ccsid 13488 not null )
insert into qtemp.p1 values(20070816)
insert into qtemp.p2 values('20070816')

Question: How to join equivalence on Z and G?
select Z ,G
from qtemp.p1 ,qtemp.p2
where char(Z) = G

Here is a scenario that I am entertaining and I would like to ask you for
your advice

There are two separate Physical files in our System that unfortunately
cannot be recreated
and we would like to have a Join file built over them.

The first physical file (P1)
-----------------------------
Has a field that is Numeric [Data type= Zoned , Field Length (10, 00
(ten 10 digits and no decimal positions), Buffer length 10]
CCSID = 65335
I will call it Field1

The Second physical file (P2)
------------------------------
Has a field that is type DBCS [Data type = Graphic, Field length 20,
Buffer length 40
CCSID = 13488
I will call it Field 2

Joined (logical) file Or SQL view
----------------------------------
The Joined file should look something like this ...
o The Character portion (10 bytes long) of the first file (P1).Field1
at CCSID = hopefully 37

Joined to
o The SubString - SST, portion of the first (10 bytes) of the second
(P2).Field2 at CCSID = hopefully 37
