int mysql_set_server_option(MYSQL *mysql, enum enum_mysql_set_option option)
Enables or disables an option for the connection. option can have one of the
following values.
| Option | Description |
|---|---|
MYSQL_OPTION_MULTI_STATEMENTS_ON |
Enable multiple-statement support |
MYSQL_OPTION_MULTI_STATEMENTS_OFF |
Disable multiple-statement support |
If you enable multiple-statement support, you should retrieve 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 22.8.17, "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.
Zero for success. Nonzero if an error occurred.
Commands were executed in an improper order.
The MySQL server has gone away.
The connection to the server was lost during the query.
The server didn't support mysql_set_server_option()
(which is the case that the server is older than 4.1.1) or the server didn't support the option one
tried to set.
