我想使用触发器将数据从表复制到另一个不重复

Question

我有两张桌子 在第一张表中，它每时每刻都添加行取决于用户插入 在表二中，我想复制每一行都已添加到表一中，但具有特定标准 并且第二张表还有一些额外的列，我稍后需要它们 我想通过触发器做到这一点，但我不知道该怎么做

我已经尝试过存储过程但不是自动的

INSERT INTO ax.RETAILTRANSACTIONSALESTRANS2
(
    [BARCODE]
    , [CREATEDDATETIME]
	,[Name]
    , [ITEMID]
    , [NETAMOUNTINCLTAX]
    , [QTY]
    , [STAFFID]
    , [TERMINALID]
    , [TRANSDATE]
	,[PERIODICPERCENTAGEDISCOUNT]
	,[ReceiptID]
)
SELECT ab.[BARCODE]
    , ab.[CREATEDDATETIME]
	,[ax].[ECORESPRODUCTTRANSLATION].[NAME]
    , ab.[ITEMID]
    , ab.[PRICE]
    , ab.[QTY]
    , ab.[STAFFID]
    , ab.[TERMINALID]
    , ab.[TRANSDATE]
	, ab.[PERIODICPERCENTAGEDISCOUNT]
	,ab.RECEIPTID
FROM ax.RetailTransactionSalesTrans ab
inner join [ax].[INVENTTABLE] on ab.[ITEMID] =[ax].[INVENTTABLE].[ITEMID]
inner join [ax].[ECORESPRODUCTTRANSLATION] on [ax].[INVENTTABLE].PRODUCT =[ax].[ECORESPRODUCTTRANSLATION].[PRODUCT]
LEFT JOIN ax.RETAILTRANSACTIONSALESTRANS2 a ON 
a.[BARCODE] = ab.[BARCODE]
    AND a.[CREATEDDATETIME] = ab.[CREATEDDATETIME]
    AND a.[ITEMID] = ab.[ITEMID] 
    AND a.[NETAMOUNTINCLTAX] = ab.[PRICE]
    AND a.[QTY] = ab.[QTY] 
    AND a.[STAFFID] = ab.[STAFFID] 
    AND a.[TERMINALID] = ab.[TERMINALID] 
    AND a.[TRANSDATE] = ab.[TRANSDATE]
	AND a.[PERIODICPERCENTAGEDISCOUNT]=ab.[PERIODICPERCENTAGEDISCOUNT]
	and a.Process=null and a.Checked=null and a.[Select]=null
	where ab.[QTY]>0 and ab.[RECEIPTID]!='' and ab.[TRANSDATE] >= DATEADD(day, @daycount*-1, GetDate())
	and NOT EXISTS(select * from ax.RETAILTRANSACTIONSALESTRANS2 where [CREATEDDATETIME] = ab.[CREATEDDATETIME])

我想将其转换为触发器，但我不知道该怎么做

注意：@daycount 我从另一张桌子上拿了它，但我通过我的程序传递了它

您可以使用下面的内容并编辑所需的列，想法是FROM Inserted您可以选择插入到主表中的所有行。

CREATE TRIGGER TRetailTransactionSalesTrans ON RetailTransactionSalesTrans
FOR INSERT
AS
BEGIN
    INSERT INTO RETAILTRANSACTIONSALESTRANS2
    SELECT [BARCODE]
        ,[CREATEDDATETIME]
        ,[Name]
        ,[ITEMID]
        ,[NETAMOUNTINCLTAX]
        ,[QTY]
        ,[STAFFID]
        ,[TERMINALID]
        ,[TRANSDATE]
        ,[PERIODICPERCENTAGEDISCOUNT]
        ,[ReceiptID]
    FROM Inserted;
END
