This example batch file contains 4 files
1. enable_openrowset_run_once.sql
	This is the sql that you need to run to enable the openrowset method, to import data
2. importdata.bat
	This is a sample batch file that calls the two files import_data.sql and create_dw.sql
3. importdata.sql
	This is a serious of sql statements that drop a table frmo the datawarehouse and import it again via odbc

E.g.
/* Drop Inmast Table */
IF EXISTS (
 SELECT 1
 FROM  INFORMATION_SCHEMA.TABLES
 WHERE  TABLE_NAME  = 'inmast'
   AND  TABLE_SCHEMA  = 'dbo'
   AND  TABLE_TYPE  = 'BASE TABLE'
 )
BEGIN
	DROP TABLE INMAST
END

/* Import Inmast Table */
select *  into inmast 
	from openrowset ('msdasql','dsn=pfwtest',
	'select itemkey,itemdescription1,productkey from inmast')

4. create_dw.sql
	This creates an optimized table called salesdata, and the relevant indexes.
