Question

I am struggling with combining the below Select Statments, I know I could cheat and add some fake columns in and then use Union, but I want to do this correctly.
Once I have them joined, I will be putting the Statment in to a XML file for use with Word and CRM4.

SELECT BILLTO_NAME, 
       BILLTO_LINE1, 
       BILLTO_LINE2, 
       BILLTO_LINE3, 
       BILLTO_CITY, 
       BILLTO_COUNTRY, 
       BILLTO_POSTALCODE, 
       ORDERNUMBER, 
       REQUESTDELIVERYBY, 
       MODIFIEDON, 
       SHIPTO_NAME, 
       SHIPTO_LINE1, 
       SHIPTO_LINE2, 
       SHIPTO_LINE3, 
       SHIPTO_CITY, 
       SHIPTO_STATEORPROVINCE, 
       SHIPTO_COUNTRY, 
       SHIPTO_POSTALCODE, 
       CREATEDBY 
FROM   SALESORDERBASE 



SELECT QUANTITY, 
       DESCRIPTION 
FROM   SALESORDERDETAILBASE 

SELECT NEW_ORDERNOTES, 
       NEW_NOTES 
FROM   SALESORDEREXTENSIONBASE 

They all have the common column of SalesOrderID, which I need to add in somewhere as well.

You can use a LEFT JOIN on the tables:

SELECT ob.SalesOrderID 
       ob.BILLTO_NAME, 
       ob.BILLTO_LINE1, 
       ob.BILLTO_LINE2, 
       ob.BILLTO_LINE3, 
       ob.BILLTO_CITY, 
       ob.BILLTO_COUNTRY, 
       ob.BILLTO_POSTALCODE, 
       ob.ORDERNUMBER, 
       ob.REQUESTDELIVERYBY, 
       ob.MODIFIEDON, 
       ob.SHIPTO_NAME, 
       ob.SHIPTO_LINE1, 
       ob.SHIPTO_LINE2, 
       ob.SHIPTO_LINE3, 
       ob.SHIPTO_CITY, 
       ob.SHIPTO_STATEORPROVINCE, 
       ob.SHIPTO_COUNTRY, 
       ob.SHIPTO_POSTALCODE, 
       ob.CREATEDBY,
       od.QUANTITY,
       od.DESCRIPTION,
       oe.NEW_ORDERNOTES,
       oe.NEW_NOTES
FROM   SALESORDERBASE ob
LEFT JOIN SALESORDERDETAILBASE od
    on ob.SalesOrderID = od.SalesOrderID
LEFT JOIN SALESORDEREXTENSIONBASE oe
    on ob.SalesOrderID = oe.SalesOrderID
