I have a table which consists of the following fields

automaat-id
automaat-type
automaat-status
contract-id

If for 1 contract-id more than 1 (so 2 or more) different automaat-id occurs with apparaat-status 'A' and automaat-type = 'Pin' or 'Comb' count this as 1 (let's call this X)
I need to have the total of X

What's the best way?

DB2 tables do not have fields, they have columns.

Also, column names use underscores, not hyphens.

what have you tried. If you say nothing, that is probably the number of responses that you will receive.

I don't think this is a rather helpful and kind answer

I haven't tried anything since I don't know where to start

Hello,

Then you need to invest some time (and maybe some $) on SQL training/education/book(s).

This kind of material is part of most basic SQL classes/texts.

We can help when there are problems, but we are not able to "teach" from scratch.

revdpoel,

Try this untested....

Code:
SELECT SUM(CNT) FROM                                           
        (SELECT COUNT(DISTINCT(CONTRACT-ID)) AS CNT
         FROM TABLE                                         
         WHERE APPARAAT-STATUS = 'A'                           
         AND   AUTOMAAT-TYPE IN ('PIN','COMB')                 
         GROUP BY CONTRACT-ID HAVING COUNT(AUTOMAAT-ID) > 1) A


Thanks,
