Example #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 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 $stmt 0 );
echo 
" $name : " ;

$comment  sqlsrv_get_field $stmt 1 );
echo 
$comment ;
?>
