hi all,
I have one small problem. Below is my query which is running on the sql prompt:
select username||'('||sid||','||serial#||') ospid = ' ||  process ||' program = ' || program username,to_char(LOGON_TIME,' Day HH24:MI') logon_time,to_char(sysdate,' Day HH24:MI') current_time,sql_address, LAST_CALL_ET   from v$session@tmoldb_cochin where status = 'ACTIVE' and rawtohex(sql_address) <> '00' and username is not null order by last_call_et;
 select max(decode(piece,0,sql_text,null)) ||max(decode(piece,1,sql_text,null)) ||max(decode(piece,2,sql_text,null)) ||max(decode(piece,3,sql_text,null)) sql_text from v$sqltext_with_newlines@tmoldb_cochin  where address = x.sql_address and piece < 4;
but when I am using the same sql in the PL/SQL block as below:
create or replace procedure showsql as
--    x number;
    cursor c1 is
 select username||'('||sid||','||serial#||
                ') ospid = ' ||  process ||
                ' program = ' || program username,
             to_char(LOGON_TIME,' Day HH24:MI') logon_time,
             to_char(sysdate,' Day HH24:MI') current_time,
             sql_address, LAST_CALL_ET
        from v$session@tmoldb_cochin
       where status = 'ACTIVE'
         and rawtohex(sql_address) <> '00'
         and username is not null order by last_call_et;
    cursor c2 is
 select max(decode(piece,0,sql_text,null)) ||
                          max(decode(piece,1,sql_text,null)) ||
                          max(decode(piece,2,sql_text,null)) ||
                     from v$sqltext_with_newlines@tmoldb_cochin
                    where address = x.sql_address
                      and piece < 4;
    for x in c1 loop
        for y in c2  loop
            if ( y.sql_text not like '%listener.get_cmd%' and
                 y.sql_text not like '%RAWTOHEX(SQL_ADDRESS)%')
                dbms_output.put_line( '--------------------' );
                dbms_output.put_line( x.username );
                dbms_output.put_line( x.logon_time || ' ' ||
                                      ' last et = ' ||
                          substr( y.sql_text, 1, 250 ) );
            end if;
        end loop;
    end loop;
Its throwing the following error:

Warning: Procedure created with compilation errors.
