int mysql_query(MYSQL *mysql, const char
*stmt_str)
Description
Executes the SQL statement pointed to by the null-terminated
string stmt_str. Normally, the string must
consist of a single SQL statement and you should not add a
terminating semicolon (“;”) or
\g to the statement. If multiple-statement
execution has been enabled, the string can contain several
statements separated by semicolons. See
Section 20.8.12, “C API Support for Multiple Statement Execution”.
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.)
If you want to know whether the statement should return a result
set, you can use
mysql_field_count() to check for
this. See Section 20.8.3.22, “mysql_field_count()”.
Return Values
Zero if the statement was successful. Nonzero if an error occurred.
Errors
-
Commands were executed in an improper order.
-
The MySQL server has gone away.
-
The connection to the server was lost during the query.
-
An unknown error occurred.
