SQL Query Needed
Hi Experts!
Hope somebody could possibly help here? Im no SQL Expert and pulling my hair out trying to find an answer!
We have a SQL Database which has a Link Database to Google BigQuery. On the SQL Server I can run the following query which returns all the data.
SELECT * FROM OPENQUERY([BQ], 'SELECT * FROM dataviews.salesdata')
What I would like to be able to do is import all this data into a table in our SQL Database called SalesData.
I only want to insert the fields that have changed though (or don't exist).
Could somebody possibly help me with a SQL Statement
Thanks in advanced for any Help offered!

Hi All!
Many thanks for everyones response.
To answer some of the questions ...
Mark Wills - Yes, SalesData Table already exists and is like for like on what will come from the BQ Query.
Table has the following Feilds
Data_1
Data_2
Data_3
Data_4
Data_5
Data_6
Data_7
Data_8
Data_1 is always Unique
Scot Pletcher - BigQuery seems to be a Royal PITA. I don't think at present (Maybe wrong) you can check for changes in the last x minutes.
Basically anything in the DB within BigQuery could change except Coloum_1 (Data_1)
The aim is to have onsite SQL with the data in. People will then query the SQL Box onsite. We have some site which have extremely low bandwidth and pulling the data live is just becoming un-workable.
Cheers!

Your question does not include enough detail dealing with logic, business process on whose basis the data you want versus the data you don't.
You further seem to be looking at comparing data ........
An update using join to compare, update.
A sample illustration of data from one and sat from the other describing what the resulting data would look like, might help clarify your need and what the possible solution might be.
