Example #1 sqlsrv_fetch() 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_rsqlsrv_errors(), true));
}

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

// Get the row fields. Field indeces start at 0 and must be retrieved in order.
// Retrieving row fields by name is not supported by sqlsrv_get_field.
$name sqlsrv_get_field$stmt0);
echo 
"$name: ";

$comment sqlsrv_get_field$stmt1);
echo 
$comment;
?>
