Modify SQL Trigger to work with BULK INSERT

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.

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.
