SELECT */ $mysqli->query("INSERT INTO t1 SELECT * FROM City ORDER BY ID LIMIT 150"); printf("%s\n", $mysqli->info); /* close connection */ $mysqli->close(); ?>`

Example 2. Procedural style
`<?php $link = mysqli_connect("localhost", "my_user", "my_password", "world"); /* check connection */ if (mysqli_connect_errno()) { printf("Connect failed: %s\n", mysqli_connect_error()); exit(); } mysqli_query($link, "CREATE TEMPORARY TABLE t1 LIKE City"); /* INSERT INTO ..
