Adrian,

Reading your two responses, I see where the comprehension problem
lies. You stated that you wanted to use the lookup to "insert data" into
the main dataset. That was saying to me that you somehow wanted the action
of the lookupcombo to cause a row to be inserted. Now it seems you were
using the term "insert" to mean "write a value".

I think you DO actually want to implement a Keysource/Lookup relationship.

?

Guessing...

create table animal (
animalID integer nn pk,
species integer,
.....,
locationID integer)

create table location (
locationID integer nn pk,
description varchar(20))

>Location could have values eg: here, there, anywhere.

LocationID Description
1 here
2 there
3 anywhere

animalID LocationID
1 1
2 1
3 2
4 3
5 1
6 3
7 2

Not necessarily; I populate comboboxes from tables very often; but that's
not the question in hand.

It can be used this way. It's just as I described in the earlier message,
except you don't drop it into a grid - use it as a stand-alone control, in
place of the tib_edit you would otherwise have there.

>How would you suggest I go about this.

Suppose qrAnimal has this SQL :

select
a.animalID,
a....,
a.locationID,
(select L.description from Location L
where L.LocationID = a.LocationID) as Loc_Name
from Animal a
where....whatever

Suppose qrLoc has this SQL:
select
LocationID,
Description
from Location

Right. Drop in the two datasources, dsAnimal hooked to qrAnimal, dsLoc
hooked to qrLoc.

Drop in the tib_lookupcombo. Set its datasource to dsLoc, set DisplayField
to Description.

Now, move to qrLoc.

KeySource: dsAnimal
KeyLinks: LocationID=qrAnimal.LocationID
KeyDescLinks: Description=Loc_Name
KeySeeking := True

Now, qrAnimal:
KeyLinks: AnimalID
RequestLive: True

Done.
