Each data source listed in the ODBC Data Sources section [<data-source-name>] of the odbc.ini file includes its own Data Source Specification section. These sections have the following format:
[<data-source-name>] Driver=<driver-path> Keyword=<attribute>
The lines following the data source name define the required and optional attributes.
The following table contains the available options that can be entered into the Data Source Specification section.
|Driver=<driver-path>||[Required] The full path to ODBC Driver for Teradata shared objects.
|Description=<data-source-desc>||[Optional] Descriptive text about the data source.|
|DBCName=<IP-addr-or-alias>||[Required] The IP address or FQDN (fully qualified domain name) of the Teradata server.
When a name is specified, ODBC Driver for Teradata automatically detects associated COP entries. For example, if the name contains a COPx suffix. For more information, see Cop Discovery.
|[Optional] The default username for logging onto a Teradata server system.|
|Password=<password>||[Optional] The password required for the default Username.
The odbc.ini file has no password security. The password is retained in unencrypted plain text and can be viewed by any user with read-access to the file. Using this feature is not recommended, because it is deprecated. For more information, see Deprecated SQL Transformations.
You can use a Teradata Wallet reference string instead of a plain text password by specifying the $tdwallet() token. For example:
For more information, see Teradata Wallet.
|[Optional] The default database associated with the specified data source.
When no value is specified for this field, it is assigned the value of the user name as entered into the Username field.
This field entry can be overridden when a new connection is specified.
All catalog functions are associated with the default database if a table owner is not specified.
Default = NOTSET
Enables Unicode Pass Through Mode for the ODBC Application.
The default value is NOTSET, which means that the UPT Mode set by the database is used. ODBC Driver for Teradata does not send anything to the database when this option is set.
