CHAPTER 9 International Languages and Character Sets
337
Client application users may see messages from the database as well as data
from the database. Some database messages, which are strings from the
language library, may include placeholders that are filled by characters from
the database. For example, if you execute a query with a column that does not
exist, the returned error messages is:
Column column-name not found
where column-name is filled in from the database.
To present these kinds of information to the client application in a consistent
manner, even if the database is in a different character set from the language
library, the database server automatically translates the characters of the
messages so that they match the character set used in the database collation.
❖ To use character translation for database messages:
• Ensure that the collation for your database is compatible with the character
set used on your computer, and with the character set used in the Adaptive
Server IQ language resource library. The language resource library differs
among different localized versions of Adaptive Server IQ.
You must check that the characters of interest to you exist in each character
set.
Messages are always translated into the database collation character set,
regardless of whether the
-ct command-line option is used.
A further character set translation is carried out if the database server
-ct
command-line option is used, and if the client character set is different from
that used in the database collation.
