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 ?>
