Question

我的查询根本不起作用，一直在努力查看错误但找不到它。说有两个相同的值，但说实话，我正在尽力证明我的代码：

SELECT

"HQCO"."Name",

正如您所看到的，所有表和值都是相关的，并与内部和外部联接相结合以补充表。这是一份报告

Answer 1

您的查询有多个问题。

1) Problem with parenthese (too '(')
2) You use left outer join on table and you test a zone of this table -> null will be excluded like it
3) Multiples Zones in your select with same name
4) Quotes for zones and alias for tables are not necessary

请尝试保留此查询：
