Converting column header and a single record into rows

Question

Lets suppose the table with only one record
col1 col2 col3-----Column Header
d1 d2 d3
i want it in following manner
column_name Column_data----Column Header
col1 d1
col2 d2
col3 d3
for this i have written the query as
select column_name,column_data from (select * from XXX where col1=123)
MODEL RETURN UPDATED ROWS
dimension by(col1)
measures (col1,0 column_name,0 column_data )
ignore nav
rules ITERATE(167)
column_name[iteration_number]=cast( iteration_number as varchar2(3)),
column_data[iteration_number]=cast( iteration_number as int)
here i am just assigning iteration_number but i want to assign name of the column and its value;
Note:--table contains nearly 200 columns

Something like (using one of my own tables):
select column_name colname,
       decode(column_name,'RUN_NO',to_char(run_no),
                          'SEARCH_ID',to_char(search_id),
                          'PROCESSING_START_DATE',to_char(processing_start_date,'DDMMYYYYHH24MISS'),
                          'PROCESSING_END_DATE',to_char(processing_end_date,'DDMMYYYYHH24MISS'),
                          'NO_OF_MATCHES',to_char(no_of_matches),
                          'ERROR_DETAILS',error_details,
                          'ADVREP_TIMESTAMP',to_char(advrep_timestamp,'DDMMYYYYHH24MISS')
              ) colvalue
from partial_search_history, (select rownum r, column_name
                              from user_tab_columns
                              where table_name = 'PARTIAL_SEARCH_HISTORY')
where run_no = 356You can build the decode by doing
SELECT ''''||COLUMN_NAME||''',TO_CHAR('||COLUMN_NAME||'),'
FROM user_tab_columns
where table_name = 'PARTIAL_SEARCH_HISTORY'A decode on DATA_TYPE field would allow you to add a format mask for DATE fields if necessary.
