Question

Consider the following table structure with data –

AdjusterID  |  CompanyID  |  FirstName  | LastName | EmailID
============================================================
1001        | Sterling    | Jane        | Stewart  | [e-mail]
1002        | Sterling    | David       | Boon     | [e-mail]
1003        | PHH         | Irfan       | Ahmed    | [e-mail]
1004        | PHH         | Rahul       | Khanna   | [e-mail]
============================================================

Where AdjusterID is the primary key. There are no. of adjusters for a company.

I need to have a query that will list single adjuster per company. i.e. I need to get the result as –

========================================================
1001 | Sterling  | Jane  | Stewart | [e-mail]
1003 | PHH       | Irfan | Ahmed   | [e-mail]
========================================================

If any one could help me that will be great.

Answer 1

One way:

SELECT * FROM Adjusters 
WHERE AdjusterID IN(SELECT min(AdjusterID) 
                    FROM Adjusters GROUP BY CompanyID)

There are a handful of other ways involving unions and iteration, but this one is simple enough to get you started.

Edit: this assumes you want the adjuster with the lowest ID, as per your example
