關於數據庫光標的一些問題,向各位大蝦請教

小弟有如下存儲過程,在PB開發環境下運行可以得到正確結果,但一到運行環境中就沒有結果了,也不報任何錯誤信息,請大蝦們指教:


這個存儲過程的目的是通過光標的從數據表中取出指寫個數的記錄,即分頁取數方式!
起先我將結果Fetch出來,做成數據窗口,開發環境可以,運行環境取不出記錄.
然後我將記錄Fetch到一個臨時表中,從臨時表中輸出記錄,也是開發環境可以,運行環境取不出記錄.
再然後我建立一個正式表,將記錄Fetch到正式表中,在PB中執行此存儲過程,結果也不能返回結果.
後來我又試過用動態SQL語句執行此存儲過程,仍然不行.

我實在是沒有辦法了,不知道到底是什麽原因
