我有這種情況，我試圖從SQL函數返回一個結果集到一個臨時表中，然後在進一步利用這個臨時表查詢。使用SQL函數的表結果的問題與來自SQL查詢的表結果進一步QUERY
最初的查詢是使用SQL視圖來返回結果集並在查詢中使用它，但是我現在試圖使這個效率更高一點，所以我將視圖更改爲sql函數以允許參數能夠查詢數據的一個子集，而不是返回視圖中的所有內容。
當我運行新的SQL函數並再次比較原始視圖時，所有東西都對齊，但是當我用新的SQL函數替換這個SQL視圖（在主SQL查詢中）時，它開始做一些奇怪的事情。
我已經包括的查詢是什麼樣的一個片段（注：我已刪除的實際名稱和臨時名稱進行替換）

當麻煩拍出這樣的，如果交換兩個「選擇」，那麼之後「插入」它的@ResultsSet的內容是相同的 - 問題是，當這個結果集被應用到JOIN的進一步下來，似乎起到了如果@resultset已經填充使用SQL函數 - 我無所適從至於爲什麼會發生這種情況。
任何幫助將不勝感激。

也在這裏是定義來自MSSQL的視圖
我注意到有一列不同，所以將編輯，看看我怎麼去。
感謝
將視圖更改爲函數後，是否檢查所有列是否正確返回正確的數據類型？我發現你對@ResultSet中的某些列使用了一些浮點數和小數，所以如果你從函數返回後丟失了一些數據，對於某些你沒有真正比較的參數，你的一個連接可能會失敗你可能會從聚結中得到不同的結果。那麼你還可以添加視圖和用於比較的功能嗎？ – DoanCan
另外我還以爲我值得一提的是，當我創建表定義（對於函數）我回顧了視圖列以確保它們實際上是相同的 – jd11
