執行更新時存儲過程失敗

我正在使用PHP的SQL Server驅動程序連接到SQL Server 2008 Express。現在，我試圖用存儲過程替換所有的SELECT，UPDATE和INSERT語句。這對於只包含SELECT語句的SP來說工作正常。但是現在我試圖用update來做一個，並且不斷收到錯誤消息「直接執行SQL;沒有遊標」。我可以使用相同的參數值從Management Studio中調用SP。執行更新時存儲過程失敗

任何想法？

乾杯亞歷

編輯：這裏有一個更新程序。有趣的是，該過程實際上執行得很好，並更新了數據。但它仍然返回一個錯誤，導致一個異常。

首先，失敗的PHP代碼：

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

如果您可以顯示您的更新存儲過程代碼，那麼它可能會幫助我們確定問題 – 2010-09-09 15:35:08

您能用文字描述這段代碼的目的是什麼？它看起來像是通過直接的'update'語句而不是使用遊標可以更高效地實現的。 – 2010-09-10 12:01:16

嗨馬丁，我知道它被炸燬了。但是它需要處理兩件事情：計算項目下載量並確保計數器對同一下載的不同版本同步。 – Alexis 2010-09-10 13:24:41
