Question

我有一个包含300列和超过1.2亿条记录的表。我想执行像

这样的查询

select * 
from tablename 
where code in ('aa','bb', ..) 
  and column1 in ('a11','a22',..)

大约有50多个列需要应用条件。

执行此查询需要两个多小时。有没有办法改善这个？

选择查询是：

SELECT Number, COUNT(Code) AS Volume
FROM TableNameTest 
WHERE LEN(Number) >= 5  
  AND Code IN ( '851','852','853','870','871','872','002','004','006','013','017')

Answer 1

因此，您希望处理至少存在一个列中的列的记录，并且至少存在一个列，该列不在集合中并且提供了其中一个代码。

我认为您不想仅仅评估一次这样的查询，因此重组或重新编制数据索引是合理的。

正常索引无济于事，索引和数据之间的跳转会使它们无法使用。 Bitmap-Indices可以工作，因为许多索引的逻辑运算速度非常快。但是，只有没有太多不同的代码和列名 - 值？但是Sql-Server没有提供这些。

这些列存储索引可能会有所帮助，sqlserver正在提供。我承认，我对这些没有经验。

或者你可以切换到oracle或postgres。但只有经过广泛的测试!!

SQL查询 - 包含300列和1.2亿条记录的表
