Few Weeks Back I posted a question and got few very good response. Actually What I am looking is the big list in single SQL query and cannot use the PL sql or allowed to create the SQL function, I had finally used good points from all reply and created the following SQL. Here I used file_name from dba_data_files . I thought it is good to share as somebody who is reall expert in SQL can do some more fine-tuning. This will atleast work good for mine requirement but may give some issue if the Text cross the Concat restriction.

  select text from (
select verse, lvl, text, rank() over(partition by verse order by lvl desc) rn from
  (
    SELECT verse, LEVEL lvl, SYS_CONNECT_BY_PATH(file_name, ',') text     FROM ( select 1 verse, rownum piece, file_name from dba_data_files )

      CONNECT BY verse = PRIOR verse
             AND piece - 1 = PRIOR piece
      START WITH piece = 1

)x
) y
where rn=1
/

Any advice or suggestion are most welcome. Tx

It works for Group by Clauses like
select table_name,stragg(index_name) from user_indexes group by table_name

Sql Gurus

I need to create the sql script that can display all tables from user_tables in one line seperated by ",". Is there any straighforward SQL that can display the result in Horizontal instead of single table in each row.
