[AccessD] Inserting a set amount of records into a table

John,

Could you build a table that has 2 columns...[switchtype] and 
[portnumber]...and basically has 24 records for the 24port switchtype...and 
48 records for the 48port...and then use an append query with that table and 
the table that says what switch type each machine is...filtered by the 
machine id or name...and append to the table where you want the 24 or 48 
ports to be listed.  I believe it is called a "Cartesian product".  
Something like:
SELECT zz_tblSwitchPortsList.Port
FROM zz_tblSwitches, zz_tblSwitchPortsList
WHERE (((zz_tblSwitches.SwitchID)=1) AND 
((zz_tblSwitchPortsList.SwitchType)="48port"));

Since there are 48 records with a switchtype of '48port'...the results would 
be 48 records for switchID 1.

Hope it helps...

Thanks,

Mark
