使用與全局臨時表合併

Question

我遇到了存儲過程問題。我正在嘗試將表var中的數據合併到全局臨時表中。我在合併後將表名稱放入時出現錯誤。這是我第一次嘗試使用它。如果我評論合併，一切正常。

有沒有人知道問題在哪裏？

當我執行的SP，我得到一個錯誤 「消息102，級別15，狀態1，過程Pickrate，109線 附近有語法錯誤## HoursByDay'。」

Answer 1

檢查數據庫的兼容性級別。

我可以將其設置爲2000或2005年。2008年重現此錯誤，一旦我刪除你的基表的所有引用它工作正常（雖然MERGE語句需要用分號來終止。）

Answer 2

儘管the documentation似乎沒有明確提及#temp或##全局臨時表，但我從來沒有見過使用它們的MERGE示例。也許是因爲MERGE ##HoursByDay應該是MERGE INTO ##HoursByDay？也許是因爲前面的陳述沒有用分號恰當地結束？不在我現在可以測試的地方，但我會嘗試這些。

無論如何，你爲什麼不使用永久表？除了最後不必刪除它之外，它可以實現與##全局臨時表相同的併發和隔離。我不明白全球臨時表在這裏買你什麼。
