觸發與identation光標[編輯]

Question

早安人，

這是我的第一篇文章在這裏，我已經工作了一個數據庫的APP我的工作，我需要在觸發我一些線索這讓我很生氣。

編輯：

鑑於未來結構：

用戶表：

[dbo].[ENGIE_Users] 
(
[dbID] [int] IDENTITY(1,1) NOT NULL, 
[Nombre] [nvarchar](100) NOT NULL, 
[Apellidos] [nvarchar](200) NOT NULL, 
[HashContraseña] [binary](64) NOT NULL, 
[Email] [nvarchar](150) NOT NULL, 
[Direccion] [nvarchar](150) NOT NULL, 
[Codigo Postal] [nvarchar](5) NOT NULL, 
[Telefono] [nvarchar](12) NOT NULL, 
[Venta a Nº Cliente] [nvarchar](10) NOT NULL, 
[POS Asignado] [nvarchar](10) NOT NULL, 
[User_Number] AS ([dbo].[EngieUsers]([dbID])), 
[Salt] [uniqueidentifier] NULL 

約束： DBID主鍵 電子郵件無PK獨特

這就是我們存放來自APP的用戶。

用戶材質表：

[dbo].[ENGIE_User_Material] 
(
[ID User] [int] NOT NULL, 
[EAN] [nvarchar](13) NOT NULL, 
[Product Number] [nvarchar](20) NOT NULL, 
[Venta] [tinyint] NOT NULL, 
[Cantidad Actual] [int] NOT NULL, 
[Cantidad Total] [int] NOT NULL, 
[Descripcion Corta] [nvarchar](100) NOT NULL, 
[PVP Neto] [decimal](38, 20) NOT NULL, 
[% DTO] [decimal](38, 20) NOT NULL, 

主鍵ID用戶+產品型號+ EAN ID用戶從用戶引用DBID。

此表用於存儲每個用戶已經對其「帳戶」進行分配的產品數量。

Orders表：

[dbo].[ENGIE_Ended_Orders] 
(
[dbID] [int] IDENTITY(1,1) NOT NULL, 
[ID User] [int] NOT NULL, 
[Procesado] [tinyint] NOT NULL, 
[Finalizado] [tinyint] NOT NULL, 
[Fecha de realizacion] [date] NOT NULL, 
[OT] [nvarchar](20) NOT NULL, 
[Order Id] AS ([dbo].[EngiePedidos]([dbID])), 
[Total Pedido] [decimal](38, 20) NULL, 

主鍵DBID

ID用戶外鍵DBID從用戶 引用此表將包含訂單的 「頭」。

訂單內容表

[dbo].[ENGIE_Order_Content]  
(
[Order Id] [int] NOT NULL, 
[Product Number] [nchar](20) NOT NULL, 
[Procesado] [tinyint] NOT NULL, 
[Finalizado] [tinyint] NOT NULL, 
[Fecha de realizacion] [date] NOT NULL, 
[Cantidad] [int] NOT NULL, 
[ID Pedido] [nchar](8) NULL, 

主鍵產品編號+訂單標識 外鍵訂單標識引用訂單DBID

因此，鑑於這種結構我需要的是下一個限制：

On User-Material： 它自己的實際數量永遠不必克服總數量。 （插入/更新）

訂單 - 內容： 當訂單被插入或更新時，它必須滿足上述限制（所以如果你問5，你必須有5個單位可供你購買此產品） 此外，當它被插入/更新/刪除時，觸發器必須計算「訂單總額」，方程式是（數量*（價格 - （價格* 100 /折扣）））。

在訂單： 所以還有兩個表（與訂單/訂單內容相同的結構，稱爲終止訂單/終止訂單的範圍）witch此表將傳遞這些表的所有行到其他2當布爾值[Finalizado] = 1，並且將恢復這些項目用戶所關聯的實際數量，這些項目位於此結束訂單中。

工作完成：

觸發器： 在用戶材料

ALTER TRIGGER [dbo].[Qty_Restriction] 
ON [ENGIE].[dbo].[ENGIE_User_Material] 
INSTEAD OF INSERT 
AS 
BEGIN 
    SET NOCOUNT ON; 
    IF(SELECT [Cantidad Actual] FROM INSERTED) > (SELECT [Cantidad Total] FROM INSERTED) 
    BEGIN 
     RAISERROR('La Cantidad Actual no debe superar la Cantidad Total',18,1); 
    END 
    ELSE BEGIN 
     INSERT INTO ENGIE.dbo.ENGIE_User_Material SELECT [ID User],[EAN], [Product Number],[Venta],[Cantidad Actual],[Cantidad Total],[Descripcion Corta], [PVP Neto],[% DTO] FROM INSERTED; 
    END 
END 

這會不會讓你插入比總量更實際數量的REG。

ALTER TRIGGER [dbo].[Qty_Restriction_2] 

ON [ENGIE].[dbo].[ENGIE_User_Material] 

INSTEAD OF UPDATE 

AS 

DECLARE @material varchar(13) 
DECLARE @pno varchar(20) 
DECLARE @usuario int 

SET @material = (SELECT [EAN] FROM INSERTED) 
SET @pno = (SELECT [Product Number] FROM INSERTED) 
SET @usuario = (SELECT [ID User] FROM INSERTED) 

BEGIN 
    SET NOCOUNT ON; 
    IF UPDATE([Cantidad Actual]) 
    BEGIN 
     IF(SELECT [Cantidad Actual] FROM INSERTED) > (SELECT [Cantidad Total] FROM INSERTED) 
     BEGIN 
      RAISERROR('La Cantidad Actual no debe superar la Cantidad Total',18,1); 
     END 
     ELSE BEGIN 
      UPDATE [ENGIE].[dbo].[ENGIE_User_Material] SET [Cantidad Actual] = (SELECT [Cantidad Actual] FROM INSERTED) WHERE [Product Number] = @pno AND [EAN] = @material AND [ID User] = @usuario 
     END 
    END 
    IF UPDATE([Cantidad Total]) 
    BEGIN 
     IF(SELECT [Cantidad Actual] FROM INSERTED) > (SELECT [Cantidad Total] FROM INSERTED) 
     BEGIN 
      RAISERROR('La Cantidad Actual no debe superar la Cantidad Total',18,1); 
     END 
     ELSE BEGIN 
      UPDATE [ENGIE].[dbo].[ENGIE_User_Material] SET [Cantidad Total] = (SELECT [Cantidad Total] FROM INSERTED) WHERE [Product Number] = @pno AND [EAN] = @material AND [ID User] = @usuario 
     END 
    END 
    IF UPDATE([Venta]) 
    BEGIN 
     UPDATE [ENGIE].[dbo].[ENGIE_User_Material] SET [Venta] = (SELECT [Venta] FROM INSERTED) WHERE [Product Number] = @pno AND [EAN] = @material AND [ID User] = @usuario 
    END 
    IF UPDATE([Descripcion Corta]) 
    BEGIN 
     UPDATE [ENGIE].[dbo].[ENGIE_User_Material] SET [Descripcion Corta] = (SELECT [Descripcion Corta] FROM INSERTED) WHERE [Product Number] = @pno AND [EAN] = @material AND [ID User] = @usuario 
    END 
    IF UPDATE([PVP Neto]) 
    BEGIN 
     UPDATE [ENGIE].[dbo].[ENGIE_User_Material] SET [PVP Neto] = (SELECT [PVP Neto] FROM INSERTED) WHERE [Product Number] = @pno AND [EAN] = @material AND [ID User] = @usuario 
    END 
    IF UPDATE([% DTO]) 
    BEGIN 
     UPDATE [ENGIE].[dbo].[ENGIE_User_Material] SET [% DTO] = (SELECT [% DTO] FROM INSERTED) WHERE [Product Number] = @pno AND [EAN] = @material AND [ID User] = @usuario 
    END 
END 

這是一樣的，但與更新。

訂單：

CREATE TRIGGER [dbo].[TransferenceOrders_Inner] 

    ON [ENGIE].[dbo].[ENGIE_Orders] 

    AFTER UPDATE 

AS 

DECLARE @material nvarchar(20) 
DECLARE @cant int 
DECLARE @cantant int 
DECLARE @usr int 

DECLARE CURSOR_CANTIDAD CURSOR FOR 
SELECT [Cantidad],[Product Number],[ID User] FROM [ENGIE].[dbo].[ENGIE_Order_Content] A, INSERTED I WHERE A.[Numero_Pedido] = I.Numero_Pedido 

BEGIN 
    SET NOCOUNT ON; 
    IF UPDATE([Finalizado]) 
    BEGIN 
     UPDATE A SET [Finalizado] = I.Finalizado FROM [ENGIE].[dbo].[ENGIE_Orders] A INNER JOIN INSERTED I ON A.dbID = I.dbID; 

     INSERT INTO [ENGIE].dbo.[ENGIE_Ended_Orders] ([Numero_Pedido],[ID User],[Fecha de realizacion],[OT],[ID Pedido],[Total Pedido]) 
    (SELECT [dbID],[ID User],[Fecha de realizacion],[OT],[Numero_Pedido],[Total Pedido] FROM INSERTED) 

     INSERT INTO [ENGIE].dbo.[ENGIE_Ended_Order_Content] ([Numero_Pedido],[Product Number],[Fecha de realizacion],[Cantidad],[ID Pedido]) 
    (SELECT [Numero_Pedido],[Product Number],[Fecha de realizacion],[Cantidad],[ID Pedido] FROM [ENGIE].[dbo].[ENGIE_Order_Content] A INNER JOIN INSERTED I ON A.Numero_Pedido = I.dbID) 

     OPEN CURSOR_CANTIDAD 
     FETCH CURSOR_CANTIDAD INTO @cant,@material,@usr 
     WHILE (@@FETCH_STATUS = 0) 
     BEGIN 
      UPDATE ENGIE.dbo.ENGIE_User_Material SET [Cantidad Actual] = (SELECT [Cantidad Actual] FROM ENGIE.dbo.ENGIE_User_Material A,INSERTED I WHERE A.[Product Number] = (SELECT [Product Number] FROM ENGIE.dbo.[ENGIE_Order_Content] B,INSERTED C WHERE B.Numero_Pedido = C.dbID) 
     AND A.[ID User] = I.[ID User])-@cant WHERE [Product Number] = @material AND [ID User] = @usr)   
      FETCH CURSOR_CANTIDAD INTO @cant,@material,@usr 
     END 
     CLOSE CURSOR_CANTIDAD; 
     DELETE A FROM [ENGIE].[dbo].[ENGIE_Orders] A INNER JOIN INSERTED I ON I.[dbID] = A.[dbID] AND A.[ID User] = I.[ID User]; 
    END 
    DEALLOCATE CURSOR_CANTIDAD; 
END 

這觸發需要遊標，因爲它有補充，它只是處理順序的內容的數量。

在Order_Content：

ALTER TRIGGER [dbo].[AutoIDOrder_DEL] 

ON [ENGIE].[dbo].[ENGIE_Order_Content] 

AFTER DELETE 

AS 

DECLARE @numped int 
DECLARE @prod nchar(20) 
DECLARE @pvp decimal(38,20) 
DECLARE @pvpsdto decimal(38,20) 
DECLARE @dto decimal(38,20) 
DECLARE @cantidad int 

SET @numped = (SELECT Numero_Pedido FROM INSERTED) 
SET @prod = (SELECT [Product Number] FROM INSERTED) 
SET @cantidad = (SELECT [Cantidad] FROM INSERTED) 
SET @pvp = (SELECT [Total Pedido] FROM [ENGIE].[dbo].[ENGIE_Orders] WHERE [dbID] = @numped) 

BEGIN 
    SET NOCOUNT ON; 
    SET @pvpsdto = (SELECT [PVP Neto] FROM [ENGIE].[dbo].[ENGIE_User_Material] WHERE [Product Number] = @prod) 
    SET @dto = (SELECT [% DTO] FROM [ENGIE].[dbo].[ENGIE_User_Material] WHERE [Product Number] = @prod) 
    UPDATE [ENGIE].[dbo].[ENGIE_Orders] SET [Total Pedido] = @pvp-(@cantidad*((@pvpsdto*100)/@dto)) WHERE [dbID] = @numped 
END 

，當你從訂單內容刪除註冊表這一次將更新從訂單「訂單總計」。

ALTER TRIGGER [dbo].[Qty_Restriction_3] 

ON [ENGIE].[dbo].[ENGIE_Order_Content] 

INSTEAD OF INSERT 

AS 

DECLARE @cantAnt int 
DECLARE @cantAct int 
DECLARE @cant int 
DECLARE @pvpsdto decimal(38,20) 
DECLARE @dto decimal(38,20) 
DECLARE @total decimal(38,20) 

SET @cant = (SELECT [Cantidad] FROM INSERTED) 
SET @cantAnt = (SELECT [Cantidad Total] FROM [ENGIE].[dbo].[ENGIE_User_Material] WHERE [Product Number] = (SELECT [Product Number] FROM INSERTED) AND [ID User] = (SELECT [ID User] FROM INSERTED)) 
SET @cantAct = (SELECT [Cantidad Actual] FROM [ENGIE].[dbo].[ENGIE_User_Material]WHERE [Product Number] = (SELECT [Product Number] FROM INSERTED) AND [ID User] = (SELECT [ID User] FROM INSERTED)) 
SET @pvpsdto = (SELECT [PVP Neto] FROM [ENGIE].[dbo].[ENGIE_User_Material] WHERE [Product Number] = (SELECT [Product Number] FROM INSERTED) AND [ID User] = (SELECT [ID User] FROM INSERTED)) 
SET @dto = (SELECT [% DTO] FROM [ENGIE].[dbo].[ENGIE_User_Material] WHERE [Product Number] = (SELECT [Product Number] FROM INSERTED) AND [ID User] = (SELECT [ID User] FROM INSERTED)) 
SET @total = (SELECT [Total Pedido] FROM [ENGIE].[dbo].[ENGIE_Orders] WHERE [dbID] = (SELECT [Numero_Pedido] FROM INSERTED)) 
IF(@total IS NULL) 
BEGIN 
    SET @total = 0.0 
END 

BEGIN 
    SET NOCOUNT ON; 
    BEGIN 
     IF((@cantAct+@cant) > @cantAnt) 
     BEGIN 
      RAISERROR('La Cantidad Actual no debe superar la Cantidad Total',18,1); 
     END 
     ELSE BEGIN 
      INSERT INTO ENGIE.dbo.ENGIE_Order_Content SELECT * FROM INSERTED; 
      UPDATE [ENGIE].[dbo].[ENGIE_Order_Content] SET [ID Pedido] = (SELECT [Numero_Pedido] FROM [ENGIE].[dbo].[ENGIE_Orders] WHERE [dbID] LIKE (SELECT [Numero_Pedido] FROM INSERTED)) WHERE [Numero_Pedido] LIKE (SELECT [Numero_Pedido] FROM INSERTED) AND [Product Number] LIKE (SELECT [Product Number] FROM INSERTED); 
      UPDATE [ENGIE].[dbo].[ENGIE_Order_Content] SET [Fecha de realizacion] = (SELECT [Fecha de realizacion] FROM [ENGIE].[dbo].[ENGIE_Orders] WHERE [dbID] = (SELECT [Numero_Pedido] FROM INSERTED)) WHERE [Numero_Pedido] LIKE (SELECT [Numero_Pedido] FROM INSERTED) AND [Product Number] LIKE (SELECT [Product Number] FROM INSERTED); 
     ----> AUQUI CALCULO DE TOTAL 

      UPDATE [ENGIE].[dbo].[ENGIE_Orders] SET [Total Pedido] = (@total+(@cant*(@pvpsdto-((@pvpsdto*@dto)/100)))) WHERE [dbID] = (SELECT [Numero_Pedido] FROM INSERTED) 
     END 
    END 
END 

這一次將避免插入訂單內容的數量不符合（實際數量< =總量）的要求+將計算總的秩序的基礎，要添加的productss到訂單。

END 

這最後一個假裝做同樣的插入，但在更新，使得實際數量的限制，工作，到[訂單總計]列

Answer 1

你觸發不處理給值多行插入。如果

SET @usuario = (SELECT [ID User] FROM INSERTED) 

返回多個值。它會失敗。觸發器內的光標是非常糟糕的事情。您應該重新使用基於集合的方式寫你的觸發 你的第一個4個報表應重新寫入

UPDATE A 
SET [Finalizado] = i.Finalizado 
FROM [ENGIE].[dbo].[ENGIE_Orders] A 
INNER JOIN INSERTED I ON a.dbID = i.dbid; 

INSERT INTO [ENGIE].dbo.[ENGIE_Ended_Orders] (
    [Numero_Pedido] 
    ,[ID User] 
    ,[Fecha de realizacion] 
    ,[OT] 
    ,[ID Pedido] 
    ) 
SELECT [dbID] 
    ,[ID User] 
    ,[Fecha de realizacion] 
    ,[OT] 
    ,[Numero_Pedido] 
FROM [ENGIE].[dbo].[ENGIE_Orders] 
FROM inserted 

INSERT INTO [ENGIE].dbo.[ENGIE_Ended_Order_Content] (
    [Numero_Pedido] 
    ,[Product Number] 
    ,[Fecha de realizacion] 
    ,[Cantidad] 
    ,[ID Pedido] 
    ) 
SELECT [Numero_Pedido] 
    ,[Product Number] 
    ,[Fecha de realizacion] 
    ,[Cantidad] 
    ,[ID Pedido] 
FROM [ENGIE].[dbo].[ENGIE_Order_Content] A 
INNER JOIN INSERTED I ON A.Numero_Pedido = I.Dbid 

DELETE A 
FROM [ENGIE].[dbo].[ENGIE_Orders] A 
INNER JOIN INSERTED I ON 
WHERE I.[dbID] = A.DBID 
    AND A.[ID User] = I.USERID; 

我不知道我見過你的標準（especillay的加入，請做一次檢查就可以了），但觸發應用基於集合的邏輯重寫，我希望光標也可以被刪除
