20.7.3.3.6. Multiple Statements
Copyright 1997-2012 the PHP Documentation Group. [2230]
MySQL optionally allows having multiple statements in one statement string. Sending multiple
statements at once reduces client-server round trips but requires special handling.
Multiple statements or multi queries must be executed with mysqli_multi_query. The individual
statements of the statement string are separated by semicolon. Then, all result sets returned by the
executed statements must be fetched.
The MySQL server allows having statements that do return result sets and statements that do not
return result sets in one multiple statement.
Example 20.100. Multiple Statements
<?php
$mysqli = new mysqli("example.com", "user", "password", "database");
if ($mysqli->connect_errno) {
echo "Failed to connect to MySQL: (" . $mysqli->connect_errno . ") " . $mysqli->connect_error;
}
if (!$mysqli->query("DROP TABLE IF EXISTS test") || !$mysqli->query("CREATE TABLE test(id INT)")) {
echo "Table creation failed: (" . $mysqli->errno . ") " . $mysqli->error;
}
$sql = "SELECT COUNT(*) AS _num FROM test; ";
$sql.= "INSERT INTO test(id) VALUES (1); ";
$sql.= "SELECT COUNT(*) AS _num FROM test; ";
if (!$mysqli->multi_query($sql)) {
echo "Multi query failed: (" . $mysqli->errno . ") " . $mysqli->error;
}
do {
if ($res = $mysqli->store_result()) {
var_dump($res->fetch_all(MYSQLI_ASSOC));
