多个表中的UNION ALL

Question

我需要UNION ALL多个表。我通过PHP创建了一个查询，并在没有UNION ALL表的情况下成功运行。但是，当我联盟所有2表，似乎查询永远不会结束于PHP页面，我也在pgAdmin中测试了相同的结果。我通过shell获取我想要选择的数据而生成一个CSV文件，但查询永远不会结束。我会赞赏你的评论。提前致谢。

这是UNION ALL查询的多个表。可以是UNION ALL的表的数量取决于DateRangePicker。所以，在每天有一个表，例如：F_UCell_1_170123，F_UCell_1_170124，F_UCell_1_170125，F_UCell_1_170126等..

@alex_edev，进出口检验（由INNER JOIN JOIN共7台），它工作正常只有一列，所以它是一个性能问题。另外，我在同一个局域网中有不同的服务器（1个用于网页，另一个用于数据库服务器）。所有列的结果约为150 MB，因此可能是网络问题。 012H@本H，表的设计是以前设计的一个已经有数据，所以重新设计表不是一个选项。
