执行更新时存储过程失败

我正在使用PHP的SQL Server驱动程序连接到SQL Server 2008 Express。现在，我试图用存储过程替换所有的SELECT，UPDATE和INSERT语句。这对于只包含SELECT语句的SP来说工作正常。但是现在我试图用update来做一个，并且不断收到错误消息“直接执行SQL;没有游标”。我可以使用相同的参数值从Management Studio中调用SP。执行更新时存储过程失败

任何想法？

干杯亚历

编辑：这里有一个更新程序。有趣的是，该过程实际上执行得很好，并更新了数据。但它仍然返回一个错误，导致一个异常。

首先，失败的PHP代码：

if (! $this->Result = sqlsrv_query($this->Conn, $strQuery, $arrParameters, array("Scrollable"=>SQLSRV_CURSOR_STATIC))) 
{ 
    $this->sendErrorMail($strQuery, $arrParameters); 
    throw new Exception(4001); 
}

如果您可以显示您的更新存储过程代码，那么它可能会帮助我们确定问题 – 2010-09-09 15:35:08

您能用文字描述这段代码的目的是什么？它看起来像是通过直接的'update'语句而不是使用游标可以更高效地实现的。 – 2010-09-10 12:01:16

嗨马丁，我知道它被炸毁了。但是它需要处理两件事情：计算项目下载量并确保计数器对同一下载的不同版本同步。 – Alexis 2010-09-10 13:24:41
