mysqli_multi_query

Performs a query on the database (PHP 5)
bool mysqli_multi_query ( mysqli link, string query )

Procedural style:

Object oriented style (method):

mysqli {
  bool multi_query(string query);
}

Executes one or multiple queries which are concatenated by a semicolon.

To retrieve the resultset from the first query you can use mysqli_use_result() or mysqli_store_result(). All subsequent query results can be processed using mysqli_more_results() and mysqli_next_result().

Parameters

link

Procedural style only: A link identifier returned by mysqli_connect() or mysqli_init()

query

The query, as a string.

Return Values

Returns FALSE if the first statement failed. To retrieve subsequent errors from other statements you have to call mysqli_next_result() first.

Examples

Example 1527. Object oriented style

<?php
$mysqli
= new mysqli("localhost", "my_user", "my_password", "world");

/* check connection */
if (mysqli_connect_errno()) {
   
printf("Connect failed: %s\n", mysqli_connect_error());
   exit();
}

$query  = "SELECT CURRENT_USER();";
$query .= "SELECT Name FROM City ORDER BY ID LIMIT 20, 5";

/* execute multi query */
if ($mysqli->multi_query($query)) {
   do {
       
/* store first result set */
       
if ($result = $mysqli->store_result()) {
           while (
$row = $result->fetch_row()) {
               
printf("%s\n", $row[0]);
           }
           
$result->close();
       }
       
/* print divider */
       
if ($mysqli->more_results()) {
           
printf("-----------------\n");
       }
   } while (
$mysqli->next_result());
}

/* close connection */
$mysqli->close();
?>


Example 1528. 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();
}

$query  = "SELECT CURRENT_USER();";
$query .= "SELECT Name FROM City ORDER BY ID LIMIT 20, 5";

/* execute multi query */
if (mysqli_multi_query($link, $query)) {
   do {
       
/* store first result set */
       
if ($result = mysqli_store_result($link)) {
           while (
$row = mysqli_fetch_row($result)) {
               
printf("%s\n", $row[0]);
           }
           
mysqli_free_result($result);
       }
       
/* print divider */
       
if (mysqli_more_results($link)) {
           
printf("-----------------\n");
       }
   } while (
mysqli_next_result($link));
}

/* close connection */
mysqli_close($link);
?>


The above example will output something similar to:

my_user@localhost
