SQLDriverConnect allows ODBC Driver for Teradata to define an arbitrary amount of connection information in the form of keyword-value pairs in the connection string. For example, a custom program that always uses the XYZ Corp data source might prompt the user for names and passwords and build the following set of keyword-value pairs, or connection string, to pass to SQLDriverConnect:
