如何用PHP调用数据库的存贮过程的教程

下面是我的一个简单的存贮过程
CREATE PROCEDURE [sp_mystoreprocedure] AS
select companyname, contactname, city from customers 其实，还可以写比较复杂的，可惜我对此研究不深，只好取简单了！ 下面是我的php文件
<?
define (“OLEDB_CONNECTION_STRING”,
“Provider=SQLOLEDB; Data Source=zzb; Initial Catalog=Northwind; User ID=sa; Password=”);
$dbc = new COM(“ADODB.Connection”);
$dbc->Open(OLEDB_CONNECTION_STRING);
$command = “sp_mystoreprocedure”;
$rs = $dbc->Execute($command); // Recordset
$i = 0; echo ‘<table cellSpacing=”1″ cellPadding=”3″ width=”600″ align=”center” bgColor=”#000000″ border=”0″>
<tr vAlign=”bottom” bgColor=”#9999cc”>
<th>Directive</th>
<th>Local Value</th>
<th>Master Value</th>
</tr>’; while (!$rs->EOF) {
$i += 1;
$fld0 = $rs->Fields(0);
$fld1 = $rs->Fields(1);
$fld2 = $rs->Fields(2);
print ‘<tr vAlign=”baseline” bgColor=”#cccccc”>
<td bgColor=”#ccccff”><b>’;
print $fld0->value;
print ‘</b><br></td>
<td align=”middle”>’;
print $fld1->value;
print ‘</td><td align=”middle”>’;
print $fld2->value;
print ‘</td></tr>’; $rs->MoveNext();
}
print ‘</TABLE>’; $rs->Close();
?>
