編寫此sql的更好方法-CTE / Temp表

Question

對於如何以更有效的方式編寫此代碼，我確實可以提供一些幫助。 我基本上是創建一個CTE來保存包含車輛的數據集，該數據集包括車輛，每天及其裝載的集裝箱的重量。 容器必須具有一定的重量，因此通過/失敗字段。

我要做的就是在CTE中獲取舉升水平詳細信息，並將其匯總為通過/未通過標准的舉升集裝箱數量，並匯總任何舉升失敗的原因。

我只是想知道最好的方法是使用CTE，還是使用臨時表或任何一種方法來加快速度或采用更標准的做法？

理想情況下，我先發布CTE數據的圖像，然后發布輸出數據，但我無法發布圖像：(

提前謝謝了

Answer 1

CTE只是語法，並且經過評估
但是，如果CTE運行得很快，那就不是問題
實現到t #temp需要付出代價
單獨運行CTE需要多長時間？
整個查詢需要很長時間？

但是您不需要兩個聯接

將總和（超重）AS超重上移至PassesandFails

將Count（lifteventid）向下移動到提升為Count（lifttext）
null不計算在內

這樣會將連接開銷減少了1/2

如果您得到期望的答案，那么發布數據沒有目的
