That includes no information?

Question

I have a table in which I have a field that is filled with SYSDATE command, inserting the other fields ...
table
CREATE TABLE "SH_RECAUDO"."G_OCCIDENTE"
(     "COD_REFERENCIA" NUMBER NOT NULL ENABLE,
     "DETALLE" VARCHAR2(64 BYTE) NOT NULL ENABLE,
     "FECHA_CREACION" DATE DEFAULT SYSDATE NOT NULL ENABLE,
     "MODICADO_POR" VARCHAR2(30 BYTE) DEFAULT USER NOT NULL ENABLE,
     "NUM_FACTURA" VARCHAR2(14 BYTE) NOT NULL ENABLE,
     "VALOR_FACTURA" NUMBER NOT NULL ENABLE,
     "TIPO_PAGO" VARCHAR2(14 BYTE) NOT NULL ENABLE,
     CONSTRAINT "G_OCCIDENTE_PK" PRIMARY KEY ("COD_REFERENCIA");
which put these 3 files separately, but I left with the same creation date ....

and when I run the following query
select FECHA_CREACION display_value
, To_char (FECHA_CREACION, 'dd / mm / yy') return_value
from G_OCCIDENTE
group by
FECHA_CREACION;
and as a result I get the following information
DISPLAY_VALUE return_value
2009-04-07 07/04/09
2009-04-07 07/04/09
2009-04-07 07/04/09
2009-04-07 07/04/09
4 rows selected
by that I do not generate a return results only if the date is the same?
DISPLAY_VALUE return_value
2009-04-07 07/04/09
I am committing that error?
I appreciate your help

Answer 1

Alex Nuijten
is correct ...
applied the wrong command trunc (), but as I have corrected, and get the result we needed,
Now I get a warning because I'm using the query within a procedure ...
Thank you very much for your help ...
I would like to know the warning removed
The procedure is as follows
create or replace Procedure archivo_G_O(pi_Fecha In Date)
As
v1 utl_file.file_type;
v2 varchar2(100);
fecha DATE;
aux varchar2(10);
Begin
-- Aqui inicia el bloque de proceso que generar el archivo de Acuavalle.
--dbms_output.put_line('LA FECHA QUE SE DESCARGA PARA LA CONSULTA ES: '||pi_Fecha);
select max(fecha_creacion) into aux from g_occidente;
--dbms_output.put_line('LA FECHA de la tabla es: '||aux);
v1 := utl_file.fopen('PUBLIC_ACCESS','GASES0000'
|| to_char(pi_Fecha, 'ddMMyyyy') || '.txt', 'w');
For rec in (SELECT GO.DETALLE cuerpo
     FROM G_OCCIDENTE GO
WHERE   trunc(GO.FECHA_CREACION) = pi_Fecha) Loop
utl_file.put_line(v1, rec.cuerpo);
End Loop;
utl_file.fclose(v1);
-- Aqui termina el bloque de proceso que generar el archivo de Acuavalle.
Exception
when others then
dbms_output.put_line(sqlerrm);
End;
