In t-sql 2008 r2, I am trying to determine how to setup the sql to accomplish the following
goal:

select table1.customer_id,type,start_date,end_date,Program_id from table1
join table2 on table1.customer_id = table2.customer_id

1. where type not= ('aa','cc') and type not = 'g2' where code = 3
In table1 there are lots of records for each customer_id and there can be
lots of various values for type. I only want the customer_ids that do not contain
the values listed above.
and
2. table2 has only one customer_id. Customer_id is the key of table2.
I want customers that do not have a value in one of the 3 columns:
start_date, end_date, and program_id.

Both parts 1 and 2 listed above need to be true for the customer_id to be selected.
Thus can you tell me how to setup that sql?

First please read the article in my signature about posting these types of questions to the forum. After you do that I could make sure that the answer is correct. Without the necessary information the following where statement should get you what you want:
where type not in ('aa', 'cc')
and type <> = 'g2'
and code = 3
and (table2.start_date is null
or table2.end_date is null
or table2.program_id is null)


Instead of all of the nulls you could use union all for each of the "is null" statements.

Just a curiosity... why did you treat 'g2' separately instead of just using...

  WHERE [Type] NOT IN ('aa','cc','g2')

RBAR is pronounced ree-bar and is a Modenism for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
Stop thinking about what you want to do to a row... think, instead, of what you want to do to a column.
If you think its expensive to hire a professional to do the job, wait until you hire an amateur. -- Red Adair

well there is that method of fixing the query. The <>= would have thrown an error ;-)
