Trigger trigger for volume insertion

Question

ALTER TRIGGER [dbo].[TR_O_SALESMAN_INS]
   ON  [dbo].[O_SALESMAN]
   AFTER INSERT
AS 
BEGIN
    -- SET NOCOUNT ON added to prevent extra result sets from
    -- interfering with SELECT statements.
    SET NOCOUNT ON;

    -- Insert statements for trigger here
    DECLARE @SLSMAN_CD NVARCHAR(20)
    DECLARE @SLSMAN_NAME NVARCHAR(20)
    SELECT @SLSMAN_CD = SLSMAN_CD,@SLSMAN_NAME=SLSMAN_NAME
    FROM INSERTED

    IF NOT EXISTS(SELECT * FROM O_SALESMAN_USER WHERE SLSMAN_CD = @SLSMAN_CD)
    BEGIN
        INSERT INTO O_SALESMAN_USER(SLSMAN_CD, PASSWORD, USER_CD)
        VALUES(@SLSMAN_CD, @SLSMAN_CD,@SLSMAN_NAME )
    END
END

This is a trigger written table(O_SALESMAN)to extract several columns from it and insert them into each other table(O_SALESMAN_USER). Currently, voluminous data is inserted into the table O_SALESMANthrough the stored procedure, where when the trigger is launched only once, and O_SALESMAN_USERhas only one record inserted each time the stored procedure is executed, I want to start the trigger after each record that is inserted into O_SALESMAN. so both tables must have the same counter that does not occur. Please let me know what can be changed in this trigger to achieve the same ....

Answer 1

:

create trigger trg_insertstuff
on [O_SALESMAN]
after insert
as

  DECLARE @SLSMAN_CD NVARCHAR(20)
    DECLARE @SLSMAN_NAME NVARCHAR(20)


 declare db_cursor CURSOR FOR  
SELECT SLSMAN_CD, SLSMAN_NAME
from inserted

OPEN db_cursor  
FETCH NEXT FROM db_cursor INTO @SLSMAN_CD , @SLSMAN_NAME 

WHILE @@FETCH_STATUS = 0  
BEGIN  

IF NOT EXISTS(SELECT * FROM O_SALESMAN_USER WHERE SLSMAN_CD = @SLSMAN_CD)
    BEGIN
        INSERT INTO O_SALESMAN_USER(SLSMAN_CD, PASSWORD, USER_CD)
        VALUES(@SLSMAN_CD, @SLSMAN_CD,@SLSMAN_NAME )
    END


FETCH NEXT FROM db_cursor INTO  @SLSMAN_CD , @SLSMAN_NAME 
end

CLOSE db_cursor  
DEALLOCATE db_cursor

scenerio is ( : Stock, StockLog)

StockLog

, ( ) ,

DECLARE @StocklId bigint

SET @StocklId = (SELECT StocklId FROM inserted)

i (SELECT StocklId FROM ), , ,

INSERT INTO StockLog(StocklId,PharmacyId,TransactionDetailId,ProductId,TotalQty,ReservedQty,AvailableQty,strUserName,strTerminalName,strVer)

SELECT StocklId, PharmacyId, TransactionDetailId, ProductId, TotalQty, 0, AvailableQty,strUserName, strTerminalName, strVer FROM inserted
