Enhancements - Teradata Tools and Utilities

Enhancements introduce new features and track changes that enhance the operation of Teradata Tools and Utilities software.

Enhancement	Description
SENTDO-351	The driver now supports the Redrive feature, if it is also enabled in the database you are connecting to. Redrive enables the driver to respond to network errors, database failures, and database restarts by automatically reconnecting to the database and resuming any requests that were interrupted. To enable this feature, enable the Enable Redrive option (or EnableRedrive property) and set the Reconnect Count option (or ReconnectCount property) to a non-zero value. You can also enable or disable Redrive on the statement level by using the SQL_ATTR_REDRIVE statement attribute. For more information, see the ODBC Driver for Teradata® User Guide, B035-2526.
SENTDO-1428	The driver has been updated to only allow Teradata Wallet reference strings to be saved in DSNs. You can no longer type passwords and authentication parameters as-is and then save those values in DSNs. As part of this update, the following updates were made to the DSN Setup dialog box:: The Authentication Parameter field was renamed to Parameter Wallet String. The Teradata Wallet String field was renamed to Password Wallet String. The Password field was removed. For more information, see the ODBC Driver for Teradata® User Guide, B035-2526.
TDS-129	The driver now supports the FastExport feature from Teradata Database. The FastExport protocol improves the performance of SELECT statements that meet certain criteria. For more information, see the ODBC Driver for Teradata® User Guide, B035-2526.
TDS-154	You can now configure the driver to return output parameters as a result set. To do this, set the OutputAsResultSet connection property to 1.
TDS-178	On Windows, the Event Logging check box is now located in the Logging Options dialog box, and is labeled Enable Event Tracing For Windows.
TDS-197	When logging is enabled, the driver now produces the following standardized log files: simbateradataodbcdriver.log: Logs driver activity that is not specific to a connection. simbateradataodbcdriver_connection_[Number].log: For each connection made to the database, where [Number] identifies each log file. This file logs driver activity that is specific to the connection.
TDS-253	When logging is enabled, the log files now include information that was previously only available through the tracing feature in the driver manager.
TDS-290	The driver now uses ICU version 58.2.x.
TDS-301	The ODBC driver for Windows is now built with Visual Studio 2019.
TDS-308	The log messages that the driver generates when logging is enabled at level 6 (TRACE) have been updated to be more detailed and precise. This includes improvements such as providing more accurate descriptions of socket errors and more consistently printing the correct session IDs.
TDS-309	The driver now includes a prefix in the names of the log files that are generated when logging is enabled. The prefix includes the user name associated with the connection and the process ID of the application through which the connection is made.
TDS-319	When connecting to the database, the driver can now detect and use the transaction isolation level that is configured on the database by default. Before, the driver sent a request to set the transaction isolation level for each connection.
TDS-320	On macOS, the driver is now built with Xcode 10.2.1.
TDS-326	The driver now supports notarization on macOS systems, enabling it to be run on macOS versions 10.14.6 and later.
TDS-347	The driver now supports stored procedures whose names include dot notation and back-ticks (`).
