Introduction to international languages and character sets

This section provides an introduction to the issues you may face when working in an environment that uses more than one character set, or when using languages other than English.

When you create a database, you specify a collating sequence or collation to be used by the database. A collation is a combination of a character set and a sort order for characters in the database.

Adaptive Server IQ international features

Adaptive Server IQ provides two sets of features that are of particular interest when setting up databases for languages.

Collations You can choose from a wide selection of supplied collations when you create a database. By creating your database with the proper collation, you ensure proper sorting of data.

Whenever the database compares strings, sorts strings, or carries out other string operations such as case conversion, it does so using the collation sequence. The database carries out sorting and string comparison when statements such as the following are executed:

Queries with an ORDER BY clause.

Expressions that use string functions, such as LOCATE, SIMILAR, SOUNDEX.
