如何調試「過程或函數'X'的存儲過程錯誤需要參數'@Y'，它沒有提供」？

Question

我的腳本如下

ALTER Procedure [dbo].[spSearch_Stock] 
    (@KeyW varchar(50), 
    @Empty int) 
AS 
BEGIN 
    SET @Empty = (SELECT COUNT(Customer) FROM tbl_Stock) 

    IF @Empty > 0 
     SELECT 
      StockID, Abb, LotNo, InvoiceNo, TeaState, Customer, Broker, 
      TeaGrade, Pkgs, NetWeight, TotWeight, PriceUSD, CurrencyRate, 
      TotalAmtUSD, BrokerageUSD 
     FROM 
      tbl_Stock 
     WHERE 
      (Abb) LIKE '%'+@Keyw+'%' 
     ORDER BY 
      StockID ASC, Abb ASC 
    ELSE 
     SELECT 
      'null' as StockID, 'null' as Abb, 'null' as LotNo, 
      'null' as InvoiceNo, 'null' as TeaState, 'null' as Customer, 
      'null' as Broker, 'null' as TeaGrade, 'null' as Pkgs, 
      'null' as NetWeight, 'null' as TotWeight, 
      'null' as PriceUSD, 'null' as CurrencyRate, 
      'null' as TotalAmtUSD, 'null' as BrokerageUSD 
END 

我得到這個錯誤：

Procedure or function 'spSearch_Stock' expects parameter '@Empty', which was not supplied

您的存儲過程有兩個參數，看來你是不及格都..

而且我看你在查詢中設置了@Empty而不考慮值是否通過，所以我建議更改您的存儲過程，如下所示：

ALTER Procedure [dbo].[spSearch_Stock] 
    (@KeyW varchar(50)) 
AS 
BEGIN 
    Declare @empty int 

    select @empty = COUNT(Customer) FROM tbl_Stock 

    -- Body of stored procedure 
END
