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')

I simply glossed over that fact that it was the same column :hehe: Just went off the OP request.

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

Knowing Keith, it was most likely just a fta fingre mistake. Afterall, he knows better than that 😀

Thank you for your help! I read the post about having well formatted code. I will definitely do that the next time of having well formatted code.
