Folks,

Does DB2 support multiple charsets?

In Oracle you can set NLS_CHARACTERSET and NLS_NCHAR_CHARACTERSET
and declare a column as CHAR or NCHAR.

We are planning to migrate our application to use Unicode and would like to
use both ASCII and Unicode character at the same time.

it's backed up on tape somewhere. Others can have their own.

You can just create a table with character column or graphic column. DB2
Administration Guide has details about the Unicode implementation in DB2.

E.g.
create table myTable (UTF8 varchar(10), UCS2 long graphic)

The column names are UTF8 and UCS2 respectively.
No you cannot specify character sets on the create table statement,
other than chosing (var)char for utf8 and (var)graphic for ucs2. You
speciy the codepage when you create the database.

O.K. I think I am begining to understand.

If I declare database code page as UTF-8, then the char, varchar, etc. will
use UTF-8 character set, and graphics, vargraphics, etc. will use USC2.

Is that correct?

Is there a document that will tell me the same thing about other code pages?
e.g. If the DB codepage is ISO8859-1 then what character sets are used for
char, etc. and graphics, etc.

The GRAPHIC datatypes may be new in the non-Asia Pacific market. Indeed, we
support Unicode GRAPHIC column in EUC database in DB2 v2, 8 years ago. In a
EUC Japanese/Tradional Chinese database, the CHAR columns are encoded in EUC
and the GRAPHIC columns are encoded in Unicode UCS-2.

Other than UTF-8 and EUC databases, the codeset of the CHAR and GRAPHIC
columns are almost the same.

GRAPHIC column is not support in SBCS databases such as ISO-8859-1.
