/* check connection */ if (maxdb_connect_errno()) { printf("Connect failed: %s\n", maxdb_connect_error()); exit(); }
$maxdb->query("CREATE TABLE temp.t1 LIKE hotel.city");
/* INSERT INTO .. SELECT */ $maxdb->query("INSERT INTO temp.t1 SELECT * FROM hotel.city"); printf("%s\n", $maxdb->info);

maxdb_query($link, "CREATE TABLE temp.t1 LIKE hotel.city");
/* INSERT INTO .. SELECT */ maxdb_query($link, "INSERT INTO temp.t1 SELECT * FROM hotel.city"); printf("%s\n", maxdb_info($link));
