[delphi-br] SQLDataSet1 : Cursor not returnet from query

[EmbarcaDelphi]

Faço assim:

DM1.SQLDataSet1.Close;
DM1.SQLDataSet1.CommandText := 'SELECT * FROM CONTROLE';
DM1.SQLDataSet1.Open;

if DM1.SQLDataSet1.RecordCount = 0 then
   Result := False;

E aparece a tela de erro:
SQLDataSet1 : Cursor not returnet from query
