Connect to a database with non-ASCII characters
If you do not specify the database name at connection time, the connection must be opened with the correct DB_LOCALE value for the specified database.
If close database and database dbname statements are issued, the connection continues to use the original DB_LOCALE value to interpret the database name. If the DB_LOCALE value of the new database does not match, an error is returned. In this case, the client program must close and reopen the connection with the correct DB_LOCALE value for the new database.
If you supply the database name at connection time, the DB_LOCALE value must be set to the correct database locale.
You can connect to an NLS database by defining a locale with NEWCODESET and NEWLOCALE connection properties. For information about their formats, see Connecting with the NEWLOCALE and NEWCODESET Environment Variables .
