Can Discoverer solve Index?

Question

Hi!!
I have a problem with Oracle9i Discoverer. I have to resolve the index:
Number of blue pencils / Total Number of pencils
and I cannot apply the condition only to the numerator, because it applies to both of them. How can I solve it?. It is the same query, but in the numerator with a condition and in the denominator wihout the condition.
Thakns in advance,
Ana

I tried following code:
SQL>select owner,table_name,index_name from dba_indexes where index_name='T_IDX';
no rows selected
SQL>drop index "t_idx";
ERROR at line 1:
ORA-01418: specified index does not exist
SQL>select index_owner, index_name, table_owner, table_name, column_name
from dba_ind_columns
where table_name = 'T'
and column_name = 'X';
INDEX_OWNER                    INDEX_NAME
TABLE_OWNER                    TABLE_NAME
COLUMN_NAME
TEST                           SYS_C005408
TEST                           T
X
Where is Alert.log? Which directory it locates?
SQL>select owner, index_name, table_owner, table_name
from user_indexes
where upper(table_name) = 'T';
ERROR at line 1:
ORA-00904: "OWNER": invalid identifier
SQL>select index_name, table_owner, table_name
from user_indexes
where upper(table_name) = 'T';
no rows selectedI don't have oracle Metalink account,where can I get 10.2.0.4 or 10.2.0.5?
Thanks
