Question

I need some help getting a SQL query running the way I need. I know you sql gurus will be laughing at this, but I really don’t know how to do this 🙁
I have two tables in a MS-SQL database. One is workers, the other is contracts. They are in a 1-to-many relationship, that is one worker can have zero or more contracts.
There was a change in the contract and all the workers were requested to sign new contracts.
What I need to get is all the workers who HAVE NOT yet signed a new contract. That is who do not have a contract after a certain date. I tried using left outer join, but it didn’t work 🙁

These are the key columns in the tables:

Workers:
WorkerID
FirstName
LastName
…

Contracts:
ContractID
Date
WorkerID
Amount
…

Any help is greatly appreciated.
Thanks.

Answer 1

select w.WorkerID, w.Firstname, w.LastName
from Workers w
left outer join Contracts c on w.WorkerID = c.WorkerID
    and c.Date > @MyDate
where c.WorkerID is null
