# Include

Main (){
MYSQL * conn;
MYSQL_RES * res;
MYSQL_ROW row;

Char * server = "localhost ";
Char * user = "root ";
Char * password = "";/* change the password here */
Char * database = "mysql ";

Conn = mysql_init (NULL );

/* Connect to database */
If (! Mysql_real_connect (conn, server,
User, password, database, 0, NULL, 0 )){
Fprintf (stderr, "% s \ n", mysql_error (conn ));
Exit (1 );
}

/* Send SQL query */
If (mysql_query (conn, "show tables ")){
Fprintf (stderr, "% s \ n", mysql_error (conn ));
Exit (1 );
}

Res = mysql_use_result (conn );

/* Output table name */
Printf ("MySQL Tables in mysql database: \ n ");
While (row = mysql_fetch_row (res ))! = NULL)
Printf ("% s \ n", row [0]);

/* Close connection */
Mysql_free_result (res );
Mysql_close (conn );
}

The content of the existing database and table is output.
