Field from which table in a JOIN table

Hi,

Would any one know how to get the field's table for SQL join table.

For example there are two table join together as follows:

COUNTRY table has two fields:

1.id
2.idname

AREA has three fields:
1. id
2. idname
3. countryid

When I use the ADOQUERY with SQL statement like :
SELECT * from AREA, COUNTRY WHERE AREA.id = COUNTRY.id

I will return 5 fields name ( by ADOQuery1.fields[q].fieldName) ;
1.id
2.idname
3.id_1
4.id_name_1
5.countryid

The question is how can I know the each field is from which table (AREA or
COUNTRY) in ADOQUERY1's property?

Thanks and Regards,
Silas
