How to run more than one query in Delphi Seatle in Firedac’s Fdquery using oracle?

Question

Using Sqlserver it is possible to run the following two queries within the same firedac Fdquery

       FDQuery.FetchOptions.AutoClose := False;

       FDQuery.sql.add('select * from tabela1');

       FDQuery.sql.add('select * from tabela2');

       FDQuery.open;

       MemTable1.Data := FDQuery.Data;

       FDQuery.NextRecordSet();

       MemTable2.Data := FDQuery.Data;

All right on Sqlserver but, someone knows how to run on Oracle?

Executing in this way:

begin
  select * from usuario;
  select * from mercadoria;
end;

this error occurs:

---------------------------
[FireDAC][Phys][Ora] ORA-06550: linha 2, coluna 3:
PLS-00428: an INTO clause is expected in this SELECT statement
ORA-06550: linha 3, coluna 3:
PLS-00428: an INTO clause is expected in this SELECT statement.
---------------------------

in this way:

select * from usuario;
select * from mercadoria;

this Error occurs:

[Firedac][Phys][Ora] ORA-00911: invalid character.
