RE: Would it be possible to Join two physical tables withmismatching data types and attributes and CCSID s?

Jorge,

No, you misunderstood what Chuck was saying about CCSID 13488. This CCSID is a double byte character set, where each character is coded as two bytes. For a ten character string to be coded in CCSID 13488, it will take twenty bytes of storage to hold it. When you use SQL to refer to this field, it translates the twenty bytes of storage into a ten character string automatically...

Chuck,


The second table that resides in our system has already been created and
the
field that I am interested in, has been defined as Graphic type, 20 bytes
long.
I would need to substring the first 10 bytes and "Join" that field

Do you think that in your example can be changed to something like this?


chgjob ccsid(37)
strsql
create table qtemp.p1 (Z numeric (10, 0) not null )
create table qtemp.p2 (G graphic (20) 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) = substring(G 1, 10)

If that is the case .. then I will be able to create an SQL view
and my permanent access will be in place!

Thanks for your reply



Jorge

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
