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。这对于只包含 SELECT 语句的 SP 来说效果很好。但现在我尝试进行更新,但不断收到错误消息“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 罚款。
有任何想法吗?
干杯

编辑:这是一个更新过程。有趣的是,该过程实际上执行得很好,并且像预期的那样更新了数据。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);
}
