Using SSIS 2012 - merge join component to transfer data to destination provided it does not exist

Question

HI Folks,
I have a table - parts_amer and this table exists in source & destination server as well.
CREATE TABLE [dbo].[Parts_AMER](
 [ServiceTag] [varchar](30) NOT NULL,
 [ComponentID] [decimal](18, 0) NOT NULL,
 [PartNumber] [varchar](20) NULL,
 [Description] [varchar](400) NULL,
 [Qty] [decimal](8, 0) NOT NULL,
 [SrcCommodityCod] [varchar](40) NULL,
 [PartShortDesc] [varchar](100) NULL,
 [SKU] [varchar](30) NULL,
 [SourceInsertUpdateDate] [datetime2](7) NOT NULL,
 CONSTRAINT [PK_Parts_AMER] PRIMARY KEY CLUSTERED
 [ServiceTag] ASC,
 [ComponentID] ASC
I need to exec the following query using SSIS components so that only that data ,is transfered,which does not exist at destination -
select source.*
from parts_amer source left join parts_amer destination
on source.ServiceTag = destination.ServiceTag
and source.ComponentID=destination.ComponentID
where destination.ServiceTag  is null and destination.ComponentID is null
Question - Can Merge component help with this?
Pl help out.
Thanks.

Hi Rvn_venky2605,
The Merge Join Transformation is used to join two sorted datasets using a FULL, LEFT, or INNER join, hence, not suitable in your scenario. As James mentioned, you can use Lookup Transformation to redirect the not matched records to the destination table.
Another option is to write a T-SQL script that makes use of
Merge statement, and execute the script via Execute SQL Task.
