Is there any best way so that I can achieve the following.

My Query is

Select text from table_A where col2 = 123 order by col1;



This query will return more than 1 number of rows.

Quote:

AAA
BBB
CCC
XXXX
YYY
ZZZ
VVV
OOO
UUU
QQQ




Now I want the desired output as :
Quote:

1. AAA 2. BBB 3. CCC 4. XXX
X 5. YYY 6. ZZZ 7. VVV 8. O
OO 9. UUU 10. QQQ



The length of the line should not exceed more than 72 characters. If it execeeds then break the line and write it in the next line. Please refer the above output and help me in getting this output.

The solution can be achieved using PL/SQL.

I didnt get the full logic for achieving thro' PL/SQL. Because when I try to get all the values in a variables..I could not ..Its showing PL/sql numeric or value error. Because the "text" column contains VARCHAR2(250) bytes. So each row contains 250 bytes...I need to mingle it altogether ..

Error? What error? I do not see any error.
Actually I don't see any code.

declare
cursor c1 is Select text from table_A where col2 = 123 order by col1;
l_txt_72 varchar2(72);
rec_txt varchar2(4000);
begin
end;
for rec in c1
loop
rec_txt := rec.text;
i := i+1;
 LOOP
	 l_txt_72 := SUBSTR(rec_txt,l_i,72);
	 IF l_txt_72 = ' '  OR l_txt_72 IS NULL THEN
	    EXIT;
	 END IF;
	 UTL_FILE.PUT_LINE(file_HandleOut, || i || '. '|| l_txt_72);
	 l_i 		:= l_i + 72;
 END LOOP;



In this i am getting pl/sql numeric error.

Please don't fake code.

This is NOT your actual code.

Start with the following:
SQL> col res format a27
SQL> with 
  2    data as (
  3      select lpad(chr(ascii('A')+level-1),
  4                  trunc(dbms_random.value(2,5)),
  5                  chr(ascii('A')+level-1)) val
  6      from dual
  7      connect by level <= 10
  8    ),
  9    numbered as ( 
 10      select row_number() over (order by val) rn, 
 11             count(*) over () cnt,
 12             val
 13      from data
 14    )
 15  select replace(substr(sys_connect_by_path(rn||'. '||val,'/'),2),'/',' ') res
 16  from numbered
 17  where rn = cnt
 18  connect by prior rn = rn-1
 19  start with rn = 1
 20  /
RES
---------------------------
1. AA 2. BBB 3. CC 4. DDDD
5. EEEE 6. FF 7. GG 8. HHHH
 9. II 10. JJ

1 row selected.
