查询执行时间超过 15 分钟，数据库是实时数据库。请建议我是否可以尝试其他方法来提高性能，例如临时表或其他东西。
我已经编辑了问题以发布确切的代码。查询需要 23 分钟才能执行。我需要修复性能。
请帮忙。
解决方案
您GROUP BY在每个子查询中使用，但没有聚合函数，如SUM()等。
您尽可能使用 distinct 代替过滤器（WHERE子句）。还有……你为什么要无条件加入表格？
(select distinct column 1, column 2 ....column n
from table 1, table 2, ..table n)
以上是笛卡尔连接。作为回报，您将获得 table1 x table2 x... tableN 行，并且您正在构建其中的两个并将它们连接在一起。更不用说你要锁定所有表谁知道多久。
没有任何样本数据，很难说出您想要实现的目标。提供更多细节。
