SQL查詢 - 包含300列和1.2億條記錄的表

2017-07-18 65 views

我有一個包含300列和超過1.2億條記錄的表。我想執行一個查詢，如SQL查詢 - 包含300列和1.2億條記錄的表

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

有大約50多列需要應用條件。

執行此查詢需要兩個多小時。有沒有辦法改善這一點？

Select查詢語句是：

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')

執行計劃中的查詢看起來並不相同 - 它顯然使用了聚合函數。另外，如果沒有模式，我們只是猜測 - 表中是否有索引？ –

所以，你想其中至少一列存在這是集合和至少一個列上存在這是處理記錄不在集合中並且提供一個代碼。

我假設你不想僅僅評估一次這樣的查詢，所以重構或重新索引你的數據是合理的。

正常索引不起作用，索引和數據之間的跳轉將使它們不可用。位圖索引可以工作，因爲在很多索引上的邏輯運算非常快。但是，只有當不存在太多不同的代碼和列名稱 - 值時？但Sql-Server不提供這些。

可能這些列存儲索引會幫助，sqlserver提供。我承認，我對這些沒有經驗。

或者你可以切換到oracle或postgres。但只有經過廣泛的測試！
