mysql_real_query()
int mysql_real_query(MYSQL *mysql, const char *query, unsigned long length)
Executes the SQL query pointed to by query
, which should be a string
length
bytes long. The query must consist of a single SQL statement.
You should not add a terminating semicolon (`;') or \g
to the
statement.
You must use mysql_real_query()
rather than
mysql_query()
for queries that contain binary data, because binary data
may contain the `\0' character. In addition, mysql_real_query()
is faster than mysql_query()
because it does not call strlen()
on
the query string.
If you want to know if the query should return a result set or not, you can
use mysql_field_count()
to check for this.
See section mysql_field_count()
.
Zero if the query was successful. Non-zero if an error occurred.
