int
mysql_query(MYSQL *mysql,
const char *stmt_str)
Executes the SQL statement pointed to by the null-terminated
string stmt_str
. Normally, the string must
consist of a single SQL statement without a terminating
semicolon (;
) or \g
. If
multiple-statement execution has been enabled, the string can
contain several statements separated by semicolons. See
Section 3.6.2, “Multiple Statement Execution Support”.
mysql_query()
cannot be used
for statements that contain binary data; you must use
mysql_real_query()
instead.
(Binary data may contain the \0
character,
which mysql_query()
interprets
as the end of the statement string.)
To determine whether a statement returns a result set, call
mysql_field_count()
. See
Section 5.4.22, “mysql_field_count()”.
