我需要關於存儲過程的幫助當涉及到數據庫時，我是一個完整而徹底的noob。我有一個客戶需要修復的程序，它是由另一個開發人員製作的，客戶似乎無法與之聯繫。逆向工程在SQL Server 2000上運行的存儲過程
這個客戶擁有這個程序，並且授予我完整的權利去做任何我喜歡的事情。問題是，這個程序使用水晶報表，並且一個特定的報告給我帶來麻煩，是StockAndSales。此報告從存儲過程填充。但問題是，即使在清空數據庫中的所有表後，報告仍顯示一些不應存在的字段。
該程序是基於.net的應用程序。
對不起，這個noobish後，但我是新來的。
P.S這個程序不是我寫的！
的程序是：

@StartDate Varchar(10),
@EndDate Varchar(10)
