Introduction to locales
CHAPTER 9
The equivalence of upper and lower case characters is enforced in the collation.
There are some collations where particular care may be needed when assuming
case insensitivity of identifiers.
In the Turkish 857TRK collation, the lower case
as its upper case equivalent. Therefore, despite the case insensitivity of
identifiers, the following two statements are not equivalent in this collation:
SELECT *
FROM sysdomain
SELECT *
FROM SYSDOMAIN
Both the database server and the client library recognize their language and
character set environment using a locale definition.
The application locale, or client locale, is used by the client library when
making requests to the database server, to determine the character set in which
results should be returned. If character-set translation is enabled, the database
server compares its own locale with the application locale to determine
whether character set translation is needed. Different databases on a server may
have different locale definitions.
For information on enabling character-set translation, see "Starting a database
server using character set translation" on page 348.
The locale consists of the following components:
The language is a two-character string using the ISO-639
•
Language
standard values: DE for German, FR for French, and so on. Both the
database server and the client have language values for their locale.
The database server uses the locale language to determine which language
library to load.
The client library uses the locale language to determine:
•
Which language library to load.
