-The demo program is designed so that a transient error (that is any error code with the prefix '08' as listed in this [appendix](https://docs.microsoft.com/sql/odbc/reference/appendixes/appendix-a-odbc-error-codes)) during an attempt to connect leads to a retry. But a transient error during query command causes the program to discard the connection and create a new connection, before retrying the query command. We neither recommend nor disrecommend this design choice. The demo program illustrates some of the design flexibility that is available to you.
