Question

我通过ODBC连接到NetSuite数据库，并为数据库创建了一个相当大的查询来运行报告。我把代码放在这篇文章的末尾。我的问题是，查询排除了“A_P_PROJECTS”表中“TRADING_PARTNER_ID”字段中具有NULL的行。我知道我可以在这里使用RIGHT OUTER JOIN，但由于我正在加入其他几个表，我似乎无法使它工作。关于我可以尝试的任何建议？

连接是只读的，所以没有临时表 - 我希望这个在单个查询中工作。谢谢你的时间！

您应该考虑对每个表使用JOIN，而不是使用WHERE子句来链接它们。如果两个表都需要包含相同的“Id”，则使用TableA INNER JOIN TableB ON TableA.Id=TableB.Id。如果您想要所有TableA记录，即使TableB中缺少某些记录，也请使用TableA LEFT JOIN TableB ON TableA.Id=TableB.Id。 TableB中没有匹配项的任何字段都将显示为NULL。

您可以嵌套所有JOIN条。我不确定 netsuite 如何处理事情，但您可能需要将()放在连接子句中。

FROM (TableA AS A INNER JOIN TableB AS B ON A.id=B.id)
                  LEFT JOIN TableC AS C ON A.id=C.id

祝你好运。
