sqlsrv_num_rows
SQL Server 2008 R2
Reports the number of rows in a result set.
sqlsrv_num_rows requires a client-side, static, or keyset cursor, and will return false if you use a forward cursor or a dynamic cursor. (A forward cursor is the default.) For more information about cursors, see sqlsrv_query and Cursor Types (SQLSRV Driver).
<?php
$server = "server_name";
$conn = sqlsrv_connect( $server, array( 'Database' => 'Northwind' ) );
$stmt = sqlsrv_query( $conn, "select * from orders where CustomerID = 'VINET'" , array(), array( "Scrollable" => SQLSRV_CURSOR_KEYSET ));
$row_count = sqlsrv_num_rows( $stmt );
if ($row_count === false)
echo "\nerror\n";
else if ($row_count >=0)
echo "\n$row_count\n";
?>
The following sample shows that when there is more than one result set (a batch query), the number of rows is only available when you use a client-side cursor.
<?php
$serverName = "(local)";
$connectionInfo = array("Database"=>"AdventureWorks");
$conn = sqlsrv_connect( $serverName, $connectionInfo);
$tsql = "select * from HumanResources.Department";
// Client-side cursor and batch statements
$tsql = "select top 2 * from HumanResources.Employee;Select top 3 * from HumanResources.EmployeeAddress";
// works
$stmt = sqlsrv_query($conn, $tsql, array(), array("Scrollable"=>"buffered"));
// fails
// $stmt = sqlsrv_query($conn, $tsql);
// $stmt = sqlsrv_query($conn, $tsql, array(), array("Scrollable"=>"forward"));
// $stmt = sqlsrv_query($conn, $tsql, array(), array("Scrollable"=>"static"));
// $stmt = sqlsrv_query($conn, $tsql, array(), array("Scrollable"=>"keyset"));
// $stmt = sqlsrv_query($conn, $tsql, array(), array("Scrollable"=>"dynamic"));
$row_count = sqlsrv_num_rows( $stmt );
echo "\nRow count for first result set = $row_count\n";
sqlsrv_next_result($stmt);
$row_count = sqlsrv_num_rows( $stmt );
echo "\nRow count for second result set = $row_count\n";
?>
