i want do that by triggers but i don't know how to do that
i'v already try stored procedure but not automatically
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])
i want to convert that as trigger but i don't how do that
note: #daycount i take it from another table but i pass that by my program

Answer 1

you can use the below and edit the needed columns , the idea is FROM Inserted you can select all rows that inserted to the main table.
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
