results from calls to
mysql_query() or
mysql_real_query() by using a
loop that calls
mysql_next_result() to determine
whether there are more results. For an example, see
Section 25.8.17, “C API Support for Multiple Statement Execution”.mysql_query()mysql_query()mysql_real_query()mysql_real_query()mysql_next_result()mysql_next_result()Section 25.8.17, “C API Support for Multiple Statement Execution”Enabling multiple-statement support with
MYSQL_OPTION_MULTI_STATEMENTS_ON does not
have quite the same effect as enabling it by passing the
CLIENT_MULTI_STATEMENTS flag to
mysql_real_connect():
CLIENT_MULTI_STATEMENTS also enables
CLIENT_MULTI_RESULTS. If you are using the
CALL SQL statement in your
programs, multiple-result support must be enabled; this means
that MYSQL_OPTION_MULTI_STATEMENTS_ON by
itself is insufficient to permit the use of
CALL.MYSQL_OPTION_MULTI_STATEMENTS_ONCLIENT_MULTI_STATEMENTSmysql_real_connect()mysql_real_connect()CLIENT_MULTI_STATEMENTSCLIENT_MULTI_RESULTSCALLCALLMYSQL_OPTION_MULTI_STATEMENTS_ONCALLCALL
