ODBC schema

Authenticator-related data is stored in a number of tables that are created using the dpdbadmin command-line utility.

For character string columns up to 1024 characters the data type VARCHAR is used. If required by the database, LONGVARCHAR or TEXT (depending on the database type) is used for columns over 1024 characters.

On Microsoft SQL Server the data type TEXT is used for columns over 8000 characters.

On Oracle the data types used for character string columns depend on the configured database character set and the national character set.
