Thanks for your response, but it does not work.

The table I use has more than five fields. I manually created one field 
(double clicking the sqlQuery and adding one field).
When I run the program, I display Query1.FieldCount : 1.
When I try to display Query1.Fields[1].fieldname ([1], i.e. the second 
fieldname) I get an "list index out of bounds" error.
Displaying Query1.Fields[0].fieldname gives the fieldname of the field I 
manually created.

So is there a way to what Lazarus can do (adding fields) by using the 
properties and/or methods of a TSQLQuery, or another component  ?

Thanks for any help,

Koenraad Lelong.
