它執行更多時間。如何減少時間？如何使用sql server減少存儲過程的時間？

看看執行計劃，看看它在做，而不是僅僅在這裏張貼SQL大規模量，並希望別人會爲你 – dbajtr

@CSK打破'存儲Procedure'到語句中的小塊並運行使用「實際執行計劃」查詢。嘗試在最常用的列上添加適當的「索引」，並檢查是否有任何正在發生的「表掃描」。 – Joby

這裏需要執行更多的時間，我想減少執行時間。請 – CSK

在等待電子郵件時，我能夠將其從動態查詢內容中轉換出來。每當你看到一個過濾器這樣的使用領域傳遞，9/10它總是將是更好的性能，以LEFT OUTER JOIN篩選器表和使用這樣的：

WHERE 
    (@FilterField1 IS NULL OR(MyTable.Field1 = @FilterField1))

你真的不需要該臨時處理您抓取主查詢中所需的字段。只需在主查詢中重新賦值給POLICY_STATUS_CODE。

同樣，不需要獲取MAX（po_term_master_pk）的子查詢，您有詳細的數據並且已經將您返回的結果分組了，爲什麼INNER JOIN中的子查詢？

您的狀態檢查會降低查詢速度。您已經擊中了主要查詢中的所有字段，然後按除狀態標誌以外的所有字段進行分組。只需使用計算字段，然後將它們彙總到外部查詢中。

下面發佈的代碼不會編譯，也不會爲您提供正確的數據，但是，您可能希望使用它來開始改進上面發佈的內容的性能。
