query... ok
MAke parameters, and use:

ADOQuery1.Close;
ADOQuery1.Parameters.ParamByName('ParamName1').value := 'value you want';
ADOQuery1.Open;

to make parameters, you have to make them Like this on the sql field of ADOQuery:

SELECT * FROM TableYouWish WHERE FieldToFilter = :ParamName1

then Delphi automatic add the parameter with the name u gave, this case 'ParamName1' and you can use it like i told before.

Simple ;)
