Modify SQL Trigger to work with BULK INSERT - sql

Question

I have a SQL Trigger that doesn't fire because the records in the table are inserted through a BULK INSERT. I do not have access to the code that inserts the records so I need to modify this trigger to handle the BULK INSERT. This is the trigger:
USE [testdata]
GO
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER TRIGGER [dbo].[Trigger_test] ON [dbo].[test]
AFTER INSERT , UPDATE
AS
BEGIN
DECLARE #BatchId int, #Ethanol decimal(18,6), #Glucose decimal(18,6), #SampleAge varchar(50);
SELECT #BatchId = CONVERT(int,bd.[BatchId]),
#Ethanol = CONVERT(decimal(18,2),[Ethanol]),
#Glucose= CONVERT(decimal(18,2),[Glucose]),
#SampleAge = bd.SampleCode
from INSERTED bd
update [dbo].[DeSchedule]
SET
[Ethanol] = #Ethanol,
[Glucose] = #Glucose,
[SampleCompleted] = 1
WHERE [BatchID] = #BatchId AND [SampleAge] = #SampleAge
END
Can anyone help me in modifying this trigger to handle the BULK INSERT.

Answer 1

Unless you can modify the BULK INSERT statement you are stuck. By default triggers do NOT run during a bulk insert. You must explicitly turn them on in the command with the FIRE_TRIGGER option.

Answer 2

Only need to edit BULK INSERT File below:
BULK INSERT AdventureWorks2012.Sales.SalesOrderDetail
FROM 'f:\orders\lineitem.tbl'
WITH
(
FIELDTERMINATOR =' |'
, ROWTERMINATOR = ':\n'
, FIRE_TRIGGERS
);

USE [testdata]
GO
SET ANSI_NULLS ON;
GO
SET QUOTED_IDENTIFIER ON;
GO
ALTER TRIGGER [dbo].[Trigger_test] ON [dbo].[test]
AFTER INSERT , UPDATE
AS
BEGIN
SET NOCOUNT ON;
DECLARE #BatchId int, #Ethanol decimal(18,6), #Glucose decimal(18,6), #SampleAge varchar(50);
Declare CurI cursor for
SELECT [BatchId],[Ethanol] ,[Glucose], SampleCode from INSERTED
Open CurI
fetch next from CurI into #BatchId,#Ethanol,#Glucose, #SampleAge
while ##fetch_status=0
Begin
update [dbo].[DeSchedule]
SET
[Ethanol] = #Ethanol,
[Glucose] = #Glucose,
[SampleCompleted] = 1
WHERE [BatchID] = #BatchId AND [SampleAge] = #SampleAge
Fetch next from CurI into #BatchId,#Ethanol,#Glucose, #SampleAge
End
Close CurI
Deallocate CurI
END

the problem is it selected only the last row of the inserted table ,i think if you change the query like this it would work
update [dbo].[DeSchedule]
SET
[Ethanol] =(select CONVERT(int,bd.[Ethanol]) from inserted bd),
[Glucose] = (select CONVERT(decimal(18,2),[Glucose]) from inserted bd),
[SampleCompleted] = 1
WHERE [BatchID] = (select CONVERT(int,bd.[BatchId]) from inserted bd) AND [SampleAge] = (select bd.SampleCode from inserted bd)
