I would like to perform a SQL union type of retrieve in WebFOCUS as in:
select * from employee where status = active union select * from employee where status = inactive
Okay the above is NOT a real sql statement that I would write, just an example.
Is there a method for performing union type operations?

TIA

Steve

Hello Steve,

You should be able to achieve this with the 'AFTER MATCH HOLD OLD-NOR-NEW' command:

In essence, using MATCH FILE you can retrieve all of the records from FILE1 and only those records from FILE2 that do NOT match those from FILE1.

MATCH File FILE1
SUM FIELD1
BY FIELD
RUN
File FILE2
SUM FIELD1
BY FIELD
AFTER MATCH HOLD OLD-NOR-NEW
END

Please see http://documentation.informationbuilders.com/masterinde...wf_user/18rpt6_1.htm for more details on how to use this command.
