Question

我正在使用PHP的SQL Server驱动程序连接到SQL Server 2008 Express。现在，我正在尝试用存储过程替换所有SELECT，UPDATE和INSERT语句。这适用于仅包含SELECT语句的SP。但是现在我尝试用更新来做一个，并且我不断收到错误消息“直接执行SQL;没有游标。”。我可以使用相同的参数值从Management Studio调用SP。

有什么想法吗？

干杯亚历

编辑：这是一个更新程序。有趣的是，该过程实际上执行得很好并且更新了它应该的数据。但它仍然返回错误，导致异常。

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);
}

Answer 1

查看权限：Executing SQL directly; no cursor

Answer 2

尝试从通话中删除"Scrollable"=>SQLSRV_CURSOR_STATIC选项。您调用的过程不会向PHP代码返回任何打开的游标。
