I've read that it is impossible to Use Query to Query Result.
Really?

Is another solution?
I want to make a search system for quering to prior query result.
I saw that kind of search system some database (but it was not delphi
appl.) Is there anyone who know the solution?

I had the same problem, too.  What I did to resolve this, was to use a
TTable to create a temporary table.
with Table1.FieldDefs do  begin
  Clear;
  Add(  ------------->  Insert field  <-----------);
  Add(  ------------->  Insert field  <-----------);
  Add(  ------------->  Insert field  <-----------);
end;
Table1.CreateTable;

I ran the first query, and used TBatchMove to append the results of the
query into Table1.  Then I can query the temp table.

Then OnFormClose, call the Table1.DeleteTable;

This is cumbersome, but it works good.

Save the query results in a temporary table using the BatchMove component or
DbiMakePermanent.  Then query the temporary table.
