我相信这个错误是因为我在我的查询模板中复制/粘贴了一个新查询，我将不得不在配置或任何其他文件中进行更多更改，我不确定。我现在正在使用一个简单的查询，如下所示，但出现相同的错误。有关如何添加新查询并继续的任何帮助

<td>
SELECT 
 DACTIONDATE
FROM WorkflowHistory
WHERE UPPER(dDocName)     = UPPER(?)
AND daction             IN('SendTo','Approve')
ORDER BY dActionDate DESC,dActionMillis;
</td> 
    <td>dDocName varchar</td>
