示例 #1 sqlsrv_get_field() example

The following example demonstrates how to retrieve a row with sqlsrv_fetch() and get the row fields with sqlsrv_get_field().


<?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 = "SELECT Name, Comment 
        FROM Table_1
        WHERE ReviewID=1";
$stmt = sqlsrv_query( $conn, $sql);
if( $stmt === false ) {
     die( print_r( sqlsrv_errors(), true));
}

// Make the first (and in this case, only) row of the result set available for reading.
if( sqlsrv_fetch( $stmt ) === false) {
     die( print_r( sqlsrv_errors(), true));
}

// Get the row fields. Field indices start at 0 and must be retrieved in order.
// Retrieving row fields by name is not supported by sqlsrv_get_field.
$name = sqlsrv_get_field( $stmt, 0);
echo "$name: ";

$comment = sqlsrv_get_field( $stmt, 1);
echo $comment;
?>
