范例

Example #1 mssql_rows_affected() example

<?php
// Delete all rows in a table
mssql_query('TRUNCATE TABLE [php].[dbo].[persons]');
echo 'Deleted ' . mssql_rows_affected($link) . ' row(s)';
?>

Note that, as the page says, this function expects an MSSQL *Link* resource, not a *result* resource. This is a bit counter-intuitive, and differs from, for instance, pg_affected_rows (though not, apparently, mysql_affected_rows).
<?php
$link = mssql_pconnect($db_host,$db_user,$db_pass);
mssql_select_db($db_name, $link);
$result = mssql_query('Select 1', $link);
$rows = mssql_rows_affected($result); # ERROR!
$rows = mssql_rows_affected($link); # Correct
?>
