Question

我正在尝试执行此语句，但我收到了此错误：

无法在数据库'tempdb'中为对象''分配空间，因为'PRIMARY'文件组已满。通过删除不需要的文件，删除文件组中的对象，向文件组添加其他文件或为文件组中的现有文件设置自动增长来创建磁盘空间。

SQL语句：

我检查过，tempdb的大小为1400mb，自动增长为10％。

我很难理解这个查询的上下文，这使我无法提供我认为答案的全部潜力。特别值得一提的是，当你通过tipoDia进行分组时，为什么你的总和乘以tipoDia的数量，我感到很困惑。

简而言之，我发现有一些事情会导致大量不合理的日志增长：

您处理日期限制的方式：您基本上需要在整个表上运行该datepart才能进行过滤。将此更改为BETWEEN，表中的列没有任何功能。
非常不寻常的嵌套：我无法理解它但我怀疑这会导致巨大的临时空间使用。我在下面给出了一些示例代码，告诉您如何摆脱这种情况，但我发现它与您原来的陈述相符并不完整。它应该能够指出你正确的方向。如果不出意外，将你的查询分成三个或四个较小的临时表，然后将它们连接在一起，而不是试图将所有内容放在一个包含许多连接的大量语句中。

NULLIFs：这实际上又与嵌套有关，但我怀疑NULLIF正在为表格的每一行列出的每一列上运行。除去嵌套语句以解决此问题，或者在嵌套部分之外添加。
