Application Using Threads Attribute ApplicationUsingThreads (AUT) Purpose Determines whether the driver works with applications using multiple ODBC threads. This connection option can affect performance. See Performance Considerations for details. Valid Values 0 | 1 Behavior If set to 1 (Enabled), the driver works with single-threaded and multi-threaded applications. If set to 0 (Disabled), the driver does not work with multi-threaded applications. If using the driver with single-threaded applications, this value avoids additional processing required for ODBC thread-safety standards. Default 1 (Enabled) GUI Tab Advanced tab
