我在

CREATE TABLE

中减少了列，使其更短，因为减少的列不参与要优化的查询

任何帮助都将不胜感激。我认为，提出问题并听取社区的建议，比一直不知情要好。提前感谢。

看看您的计划，大多数资源似乎都被排序操作消耗掉了：

为了对这些数据进行预排序，我可能会创建以下索引：

CREATE NONCLUSTERED INDEX IX_FactLoad_StationFromCode_StationToCode_idCompanyOperator_NaklID
ON dbo.FactLoad (StationFromCode, StationToCode, id_CompanyOperator, NaklID)
INCLUDE (TariffInvRF, TariffOwnRF, ID);

这应该会改善它，但可能不会创造奇迹。如果确实如此，可以进一步研究和调查

更新：

尝试使用

ColumnStore

索引

使用

列存储

索引进行测量

ColumnStore

索引，包括实际执行计划：01:02 分钟，不包括实际执行计划为：01:01分钟

ColumnStore

索引的代码为

CREATE NONCLUSTERED COLUMNSTORE INDEX 
   [csi_FactLoad_StationFromCode_StationToCode_idCompanyOperator_NaklID] ON 
   [dbo].[FactLoad] ( [NaklID], [StationFromCode], [StationToCode], 
   [id_CompanyOperator], [ID], [TariffInvRF], [TariffOwnRF] )WITH 
   (DROP_EXISTING = OFF, COMPRESSION_DELAY = 0) ON [PRIMARY]

我们需要查询计划（）和表的DDL来帮助您。@MJH OP已编辑。上面写的是几秒钟前。：）有相当大的3.5分3.3秒：）我看不到任何东西会特别使查询不可搜索。但是，我建议将{SubQuery}中的

cf.id_schodmen更改为EXISTS
@step。此链接应该可以帮助您：谢谢，我们也确实需要索引的定义。请。：）谢谢你的回复！我在[dbo].[FactLoad]（[NaklID]ASC、[StationFromCode]ASC、[StationFromCode]ASC、[id\U CompanyOperator]ASC）的[id]、[TariffInvRF]、[TariffOwnRF]）上添加了一个索引创建非聚集索引[IX\FactLoad\U StationFromCode]ASC、[id\U CompanyOperator]ASC）（PAD_INDEX=OFF，STATISTICS_norecocomputer=OFF，SORT_IN_TEMPDB=OFF，DROP_EXISTING=OFF，ONLINE=OFF，ALLOW_ROW_LOCKS=ON，ALLOW_PAGE_LOCKS=ON）ON[主]上GO
。执行时间为3:39分钟。查询计划为Heya，索引列的顺序不正确-NaklID
被移到了开头而不是结尾。因此排序操作仍然存在，并且没有性能改进。ColumnStore
索引包含实际执行计划
：01:02分钟
，但不包括实际执行计划

是：

01:01

分钟。代码是

在[dbo].[FactLoad]（[NaklID]，[StationFromCode]，[StationFromCode]，[StationFromCode]，[stationcode]，[id公司运营商]，[id]，[tariffinrf]，[tarifownrf]上创建非聚集列存储索引[PRIMARY]上的（DROP\u EXISTING=OFF，COMPRESSION\u DELAY=0）已经足够好了，所以columnstore索引似乎工作得最好。：）好的，您应该看看执行计划。可能还需要进行分拣操作。
