Choosing the code page, territory, and collation for your database
The database code page determines what characters you can
store in the database. For example, if the database code page is 819,
then only English and western European characters can be stored in
the database. A code page is a numeric value given to a named code
set.
Supported territory codes and code pages
The following tables show the languages and code sets supported
by the database servers, and how these values are mapped to territory
code and code page values that are used by the database manager.
Locale names for SQL and XQuery
When used in an SQL or XQuery
statement, a locale name consists of one or more ordered pieces of
information. The CLDR version prefix, language code, script code,
country/region code, and variant codes must be separated with the
underscore character (_). Keywords are introduced with the commercial
at symbol (@) and multiple keywords are separated by the semicolon
character (;).
Derivation of code page values
The application code page is
derived from the active environment when the database connection is
made. When you create
a database, you can explicitly specify the database code page.
If you do not specify the database code page, the database uses Unicode
by default.
Linux and UNIX distributions and code pages
Newer versions of Linux distributions
and UNIX operating systems (such
as AIX®) are starting to use
Unicode (UTF-8) as the default code page for many of their locales.
