ODBC operations return success, error or‘success with info'. This section explains how results from the ODBC layer are reported to Prolog.
If an ODBC operation returns‘with info', the info is extracted
from the interface and handled to the Prolog message dispatcher print_message/2.
The level of the message is
informational and the term is
of the form:
If an ODBC operation signals an error, it throws the exception
arguments of the
odbc(State, Native, Message), _)
odbc/3 term are explained in section
