I have problems to apply filter on my Firebird database.

if ALookupEdit.Text<>'' then
begin
TempFilter := 'AKIND =' + QuotedStr(ALookupEdit.Text);
if Filter <> '' then TempFilter := Filter+' and '+TempFilter;
ListQREP.Dataset.Filter := TempFilter;
end;
ListQREP.Dataset.Filtered := True;

this seems not related with Firebird-support.

But, I tried the search the web and I learned that filtering record
in firebird is same as using WHERE clause in SQL.
Is it true?

I could not find any documentation/sample source about it.

Any help will be appreciated.

Best Regards
