Sql server 触发器'；带标识光标的s[编辑]

大家早上好

这是我在这里的第一篇文章，我一直在为我的工作应用程序的数据库工作，我需要一些关于我的触发器的线索，这让我发疯

编辑：

鉴于下一个结构：

用户表：

[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

限制条件： dbID主键 电子邮件无Pk唯一

这里是我们存储应用程序用户的地方

用户材料表：

[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,

主键ID用户+产品编号+EAN ID user从用户引用dbID

此表用于存储每个用户分配到其“帐户”的产品数量

订单表：

[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,

主键dbID

ID用户外键引用来自用户的dbId 此表将包含订单的“标题”

ALTER TRIGGER [dbo].[Qty_Restriction_4]

INSTEAD OF UPDATE

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

订单内容表

[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,

主键产品编号+订单Id 外键订单Id引用订单dbID

因此，考虑到这种结构，我需要的是下一个限制：

关于用户材料： 它自身的实际数量永远不必超过总量。（插入/更新）

关于订单内容： 插入或更新订单时，必须满足上述限制（因此，如果您要求5台，您必须有5台可供购买的产品） 此外，在插入/更新/删除时，触发器必须计算公式中的“订单总额”（数量*（价格-（价格*100/折扣）））

奉命： 因此还有两个表（与订单/订单内容结构相同，称为End Orders/End Order Con Content），当布尔值[Finalizado]为1时，此表将把这些表的所有行转移到其他两个表。并将恢复与此结束订单中的项目用户关联的实际数量

已完成的工作：

触发因素： 关于用户资料

ALTER TRIGGER [dbo].[Qty_Restriction]

BEGIN
    SET NOCOUNT ON;

    END 
    ELSE BEGIN

这不允许您插入实际数量大于总数量的reg

这一个相同，但有更新

奉命：

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

    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 

这个触发器需要游标，因为它必须补充刚刚处理的订单内容的数量

关于订单内容：

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

当您从订单内容中删除注册表时，此项将从订单中更新“订单总数”

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

END

这将避免在订单内容中插入不符合要求的数量（实际数量您触发的触发器不处理多行插入。如果

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

返回多个值。它将失败。触发器中的游标是非常糟糕的事情。您应该使用基于集合的方法重新编写触发器 你的前4个陈述应该重写
