我寫過這個查詢，並且因爲我使用了臨時表（第一次），所以它大量地殺死了查詢的性能。臨時表查殺性能
這是查詢。你能發現我正在犯的一個巨大的錯誤嗎？

堆棧溢出不能這樣工作。您無法轉儲數百行SQL代碼，並希望任何人都能對其進行篩選。 _編輯你的問題，也許讓我們看看哪一個查詢有臨時表的問題。 –
與你的問題沒有關係，但是我不認爲這是一個好的設置，如果你是新的SQL Server（而不是）'SET TRANSACTION ISOLATION LEVEL READ UNCOMMITTED;' – Horia
嗨Horia，你可以請擴展一下嗎？爲什麼SET TRANSACTION ISOLATION LEVEL READ UNCOMMITTED;不合適？謝謝！ –
