mysqli_stmt_store_result

(PHP 5)

mysqli_stmt_store_result

(no version information, might be only in CVS)

mysqli_stmt->store_result -- Transfers a result set from a prepared statement

Description

Procedural style:

bool mysqli_stmt_store_result ( object stmt)

Object oriented style (method):

class mysqli_stmt {

bool store_result ( void )

}

You must call mysql_stmt_store_result() for every query that successfully produces a result set (SELECT, SHOW, DESCRIBE, EXPLAIN), and only if you want to buffer the complete result set by the client, so that the subsequent mysql_fetch() call returns buffered data.

Note: It is unnecessary to call mysql_stmt_store_result() for other queries, but if you do, it will not harm or cause any notable performance in all cases. You can detect whether the query produced a result set by checking if mysql_stmt_result_metadata() returns NULL.

Return values

Returns TRUE on success or FALSE on failure.

Example

Example 1. Object oriented style

<?php
/* Open a connection */
$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 Name, CountryCode FROM City ORDER BY Name LIMIT 20";
if (
$stmt = $mysqli->prepare($query)) {

    
/* execute query */
    
$stmt->execute();

    
/* store result */
    
$stmt->store_result();

    
printf("Number of rows: %d.\n", $stmt->num_rows);

    
/* free result */
    
$stmt->free_result();

    
/* close statement */
    
$stmt->close();
}

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

Example 2. Procedural style

<?php
/* Open a connection */
$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 Name, CountryCode FROM City ORDER BY Name LIMIT 20";
if (
$stmt = mysqli_prepare($link, $query)) {

    
/* execute query */
    
mysqli_stmt_execute($stmt);

    
/* store result */
    
mysqli_stmt_store_result($stmt);

    
printf("Number of rows: %d.\n", mysqli_stmt_num_rows($stmt));

    
/* free result */
    
mysqli_stmt_free_result($stmt);

    
/* close statement */
    
mysqli_stmt_close($stmt);
}

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

The above examples would produce the following output:

Number of rows: 20.
