Examples

Example #1 sqlsrv_execute() example

This example demonstrates how to prepare a statement with sqlsrv_prepare() and re-execute it multiple times (with different parameter values) using sqlsrv_execute().


<?php
$serverName = "serverName\sqlexpress";
$connectionInfo = array( "Database"=>"dbName", "UID"=>"username", "PWD"=>"password");
$conn = sqlsrv_connect( $serverName, $connectionInfo);
if( $conn === false) {
    die( print_r( sqlsrv_errors(), true));
}

$sql = "UPDATE Table_1
        SET OrderQty = ?
        WHERE SalesOrderID = ?";

// Initialize parameters and prepare the statement. 
// Variables $qty and $id are bound to the statement, $stmt.
$qty = 0; $id = 0;
$stmt = sqlsrv_prepare( $conn, $sql, array( &$qty, &$id));
if( !$stmt ) {
    die( print_r( sqlsrv_errors(), true));
}

// Set up the SalesOrderDetailID and OrderQty information. 
// This array maps the order ID to order quantity in key=>value pairs.
$orders = array( 1=>10, 2=>20, 3=>30);

// Execute the statement for each order.
foreach( $orders as $id => $qty) {
    // Because $id and $qty are bound to $stmt1, their updated
    // values are used with each execution of the statement. 
    if( sqlsrv_execute( $stmt ) === false ) {
          die( print_r( sqlsrv_errors(), true));
    }
}
?>

Notes

When you prepare a statement that uses variables as parameters, the variables are bound to the statement. This means that if you update the values of the variables, the next time you execute the statement it will run with updated parameter values. For statements that you plan to execute only once, use sqlsrv_query().

If you're used to working with sqlsrv_query, you're probably used to the following flow:

<?php
$query = "SELECT * FROM mytable WHERE id=?";
$result = sqlsrv_query($conn, $query, array($myID));
$row = sqlsrv_fetch_array($result);
?>

Given that, you might think the following works:

<?php
$myID = 0;
$query = "SELECT * FROM mytable WHERE id=?";
$stmt = sqlsrv_prepare($conn, $query, array(&$myID));
$result = sqlsrv_execute($stmt);
$row = sqlsrv_fetch_array($result);
?>

It doesn't. The reason is that sqlsrv_execute, as noted above, returns true or false on success or failure, respectively. The variable that has your result is actually $stmt. Change the last row to 

<?php
$row = sqlsrv_fetch_array($stmt);
?>

and it works as expected.
