System Processing | International Character Set Support | Teradata Vantage - System Processing of Character Data - Teradata Vantage - Database Engine 20

The system processes the character data in client requests to the database as follows:

1. A user submits a request in the character set specified as the client default.
2. The database converts the client characters it receives to the default server character set (external-to-internal, or E2I conversion) for processing and data storage.
3. The database converts data from the internal database character set back to the client character set (internal-to-external, or I2E conversion) when returning answers sets to the requesting client.

For information on character conversion options, see Character Conversion.
