Andrea,
>From Metalink, the column is defined in uppercase:
SQL> select online from v$recover_file;
select online from v$recover_file
*
ERROR at line 1:
ORA-00936: missing expression
SQL> select "ONLINE" from v$recover_file;
no rows selected
Also, online is a reserved word and that is why you originally get the
ora-00936 error:
SQL> select * from v$reserved_words where keyword ='ONLINE';
KEYWORD LENGTH
---------------------------------------------------------------- ----------
ONLINE 6

All, I got a problem with v$recover_file. Somehow the
query failed if selecting is on ONLINE column.
SQL> desc v$recover_file;
Name Null? Type
----------------------------- --------
---------------
FILE# NUMBER
ONLINE VARCHAR2(7)
ERROR VARCHAR2(18)
CHANGE# NUMBER
TIME DATE
These are OK:
-------------------
select CHANGE# from v$recover_file;
select TIME from v$recover_file;
select * from v$recover_file;
However these gave me error:
------------------------------------
select ONLINE from v$recover_file;
select online, ERROR from v$recover_file;
select FILE# , ONLINE,ERROR , CHANGE#,TIME from
v$recover_file;
*
ERROR at line 1:
ORA-00936: missing expression
SQL> select v.name, b.online
2 from v$datafile v, v$recover_file b
3 where v.file# = b.file#;
select v.name, b.online
*
ERROR at line 1:
ORA-01747: invalid user.table.column, table.column, or
column specification
What's happening?! Thank you.
Andrea
