The ODBC Programmer's Reference defines how ODBC drivers should interpret the SQLSetEnvAttr attribute specifications from applications written to either the ODBC 2.x or ODBC 3.x API. The [!INCLUDEssNoVersion] Native Client ODBC driver complies with those rules.
One of the attributes controlled by SQLSetEnvAttr is whether connection pooling is to be used. If connection pooling is used with the [!INCLUDEssNoVersion] Native Client ODBC driver, the DriverCompletion parameter must be set to SQL_DRIVER_NOPROMPT when connecting with either SQLDriverConnect or SQLConnect.
