Question

我有一个名为insert2Newsletter的存储过程，其参数为

(@sex nvarchar(10),
@f_name nvarchar(50),
@l_name nvarchar(70),
@email nvarchar(75),
@ip_address nvarchar(50),
@hotelID int,
@maArt nchar(2))

我想在插入触发器中调用此存储过程。如何从插入中检索相应的字段以及如何在触发器中调用insert2Newsletter？

我尝试没有成功：

SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE TRIGGER RA2Newsletter 
   ON  [dbo].[Reiseagent] 
   AFTER INSERT
AS 
DECLARE @rAgent_Name nvarchar(50),
DECLARE @rAgent_Email nvarchar(50),
DECLARE @rAgent_IP nvarchar(50),
DECLARE @hotelID int

BEGIN
    SET NOCOUNT ON;

    -- Insert statements for trigger here
    Select @rAgent_Name=rAgent_Name, @rAgent_Email=rAgent_Email, @rAgent_IP=rAgent_IP, @hotelID=hotelID  From Inserted
    EXEC insert2Newsletter '','',@rAgent_Name,@rAgent_Email,rAgent_IP,@hotelID,'RA' 


END
GO

很多你的反馈...问候......

Answer 1

最后...

set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON

GO
ALTER TRIGGER [dbo].[RA2Newsletter] 
   ON  [dbo].[Reiseagent] 
   AFTER INSERT
 AS
    declare
    @rAgent_Name nvarchar(50),
    @rAgent_Email nvarchar(50),
    @rAgent_IP nvarchar(50),
    @hotelID int,
    @retval int


BEGIN
    SET NOCOUNT ON;

    -- Insert statements for trigger here
    Select @rAgent_Name=rAgent_Name,@rAgent_Email=rAgent_Email,@rAgent_IP=rAgent_IP,@hotelID=hotelID  From Inserted
    EXEC insert2Newsletter '','',@rAgent_Name,@rAgent_Email,@rAgent_IP,@hotelID,'RA', @retval

END

我认为你必须遍历“inserted”表，其中包含所有已更新的行。如果主键是GUID，则可以使用WHERE循环或WITH语句。这对我来说更简单（对我而言），所以这是我的例子。我们使用这种方法，所以我知道它可以正常工作。

ALTER TRIGGER [dbo].[RA2Newsletter] ON [dbo].[Reiseagent]
    AFTER INSERT
AS
        -- This is your primary key.  I assume INT, but initialize
        -- to minimum value for the type you are using.
        DECLARE @rAgent_ID INT = 0

        -- Looping variable.
        DECLARE @i INT = 0

        -- Count of rows affected for looping over
        DECLARE @count INT

        -- These are your old variables.
        DECLARE @rAgent_Name NVARCHAR(50)
        DECLARE @rAgent_Email NVARCHAR(50)
        DECLARE @rAgent_IP NVARCHAR(50)
        DECLARE @hotelID INT
        DECLARE @retval INT

    BEGIN 
        SET NOCOUNT ON ;

        -- Get count of affected rows
        SELECT  @Count = Count(rAgent_ID)
        FROM    inserted

        -- Loop over rows affected
        WHILE @i < @count
            BEGIN
                -- Get the next rAgent_ID
                SELECT TOP 1
                        @rAgent_ID = rAgent_ID
                FROM    inserted
                WHERE   rAgent_ID > @rAgent_ID
                ORDER BY rAgent_ID ASC

                -- Populate values for the current row
                SELECT  @rAgent_Name = rAgent_Name,
                        @rAgent_Email = rAgent_Email,
                        @rAgent_IP = rAgent_IP,
                        @hotelID = hotelID
                FROM    Inserted
                WHERE   rAgent_ID = @rAgent_ID

                -- Run your stored procedure
                EXEC insert2Newsletter '', '', @rAgent_Name, @rAgent_Email,
                    @rAgent_IP, @hotelID, 'RA', @retval 

                -- Set up next iteration
                SET @i = @i + 1
            END
    END 
GO

我当然希望这会帮助你。干杯！

以下应该可以做到 - 只有SqlServer

Alter TRIGGER Catagory_Master_Date_update ON Catagory_Master AFTER delete,Update
AS
BEGIN

SET NOCOUNT ON;

Declare @id int
DECLARE @cDate as DateTime
    set @cDate =(select Getdate())

select @id=deleted.Catagory_id from deleted
print @cDate

execute dbo.psp_Update_Category @id

END

Alter PROCEDURE dbo.psp_Update_Category
@id int
AS
BEGIN

DECLARE @cDate as DateTime
    set @cDate =(select Getdate())
    --Update Catagory_Master Set Modify_date=''+@cDate+'' Where Catagory_ID=@id   --@UserID
    Insert into Catagory_Master (Catagory_id,Catagory_Name) values(12,'Testing11')
END

Answer 4

您在EXEC中传递未定义的rAgent_IP参数而不是本地变量@rAgent_IP。

但是，如果执行多记录INSERT语句，此触发器将失败。

在SQL Server中的“创建触发器”中调用存储过程
