刪除在存儲過程中不起作用

Question

我使用以下命令來執行存儲過程，但刪除不會運行。問題是什麼？

exec sp_delete 'fruits', '''1.5'',''3.5''' 

sp_delete

CREATE PROCEDURE [dbo].[sp_delete] 
@stock_type VARCHAR(255) 
,@weight VARCHAR(255) 

AS 

IF @stock_type ='fruits' 
BEGIN TRY 
IF EXISTS(SELECT * FROM tblshop WHERE quantity='1' and weight in (@weight)) 
    BEGIN 
     DELETE FROM tblshop WHERE quantity='1' and weight in (@weight) 
    END 
END TRY 
BEGIN CATCH 
END CATCH 

Answer 1

讓它動態：

CREATE PROCEDURE [dbo].[sp_delete] 
@stock_type VARCHAR(255) 
,@weight VARCHAR(255) 
AS 
declare @sql as nvarchar(max) 
IF @stock_type ='fruits' 
BEGIN TRY 
set @sql = ' 
IF EXISTS(SELECT * FROM tblshop WHERE quantity=''1'' and weight in (' + @weight + ')) 
    BEGIN 
     DELETE FROM tblshop WHERE quantity=''1'' and weight in (' + @weight + ') 
    END' 
exec(@sql) 
END TRY 
BEGIN CATCH 
END CATCH 

，並把它作爲[更新與評論在線]

exec sp_delete 'fruits', '1.5,3.5'

您需要拆分@weight值成陣列狀，如

然後WHERE quantity='1' and weight in dbo.splitFunc(@weight)
