I think, your session is terminated by Oracle. Look for any core files or
trace files and start to trace your session.
Thank You,

Hi all,
Does someone know what this error mean?
"end-of-file on communication channel"
I have the following table, with no rows stored:
name | data_type | nullable | data_default | data_length
--------------- + --------- + -------- + ------------- + -----------
COD_MALATTIA | NVARCHAR2 | Y | NULL | 20
COD_MATRICE | NVARCHAR2 | Y | NULL | 20
COD_NAZIONE | NVARCHAR2 | Y | NULL | 6
DATA_FINE | DATE | Y | NULL | 11
DATA_INIZIO | DATE | N | CURRENT_DATE | 11
ID | NUMBER | N | NULL | 38
ID_MACELLAZIONE | NUMBER | N | NULL | 38
I tried these queries:
select count(*) from restrizione where COD_MALATTIA is not null
count(*)
--------
0
select count(*) from restrizione where COD_MATRICE is not null
count(*)
--------
0
select count(*) from restrizione where COD_NAZIONE is not null
count(*)
--------
0
select count(*) from restrizione where DATA_INIZIO is not null
count(*)
--------
0
select count(*) from restrizione where ID is not null
count(*)
--------
0
select count(*) from restrizione where ID_MACELLAZIONE is not null
count(*)
--------
0
select count(*) from restrizione
count(*)
--------
0
but this one raises the error
select count(*) from restrizione where DATA_FINE is not null
ORA-03113: end-of-file on communication channel
Only when I use DATA_FINE column in the WHERE clause it raise the error.
what's wrong with this column?
Thanks for any help.
