我正在尝试在Prophet 21数据库（Epicor的erp软件）中为数据门户的ssrs报告服务运行以下查询，并且尝试在Visual Basic中输入报告时遇到一些错误。我收到以下错误：
保存查询设计方法时发生错误。具有相同键的项目已经添加。

答案 0 :(得分：1)
错误是因为您有两个具有相同名称的列：
oe_hdr.order_date,
po_hdr.order_date,
您需要为其中之一加上别名
与
相同po_line.po_no,
oe_hdr.po_no,
请确保您正确设置代码格式，以使其易于阅读
找到它们的最简单方法是将代码复制并粘贴到Notepad ++中，然后双击每个列名。.notepad将在同一文档中突出显示该单词的所有实例。.
