Dear All,

I have a varchar column whose content I have to split based on condition.

E.g
   London 
   SOO
   Val
   Gatwick 

I want to split the data and store in different column as below
Key value
London SOO
Details Gatwick

Input data
CREATE TABLE STG_TEST_DATA(ID NUMBER , VAL VARCHAR2(2000));

INSERT INTO STG_TEST_DATA VALUES( 3,'OTHR
LB
Val
Kenn / Cam Tn via Charing X');

INSERT INTO STG_TEST_DATA VALUES( 2,'CONTACT
LAS
Val
Updated');

Expected Output

id    Key       value
3      OTHR      LB
3      Val       Kenn / Cam Tn via Charing X
2      OTHR      LAS
2      Val       Updated

can some body suggest a solution



[Edit MC: fix code tags and add them to expected output, also add ";" to statements]

Here's a way, assuming the "condition" is keys/values are separated by newline:
SQL> col Key format a10
SQL> col value format a30
SQL> with
  2    data  as (
  3      select id, column_value-1 nb, regexp_substr(val, '[^'||chr(10)||']+', 1, column_value) val
  4      from STG_TEST_DATA,
  5           table(cast(multiset(select level from dual
  6                               connect by level <= regexp_count(val,chr(10))+1)
  7                 as sys.odciNumberList))
  8    )
  9  select id,
 10         max(decode(mod(nb,2),0,val)) "Key",
 11         max(decode(mod(nb,2),1,val)) "value"
 12  from data
 13  group by id, trunc(nb/2)
 14  order by id, trunc(nb/2)
 15  /
        ID Key        value
---------- ---------- ------------------------------
         2 CONTACT    LAS
         2 Val        Updated
         3 OTHR       LB
         3 Val        Kenn / Cam Tn via Charing X

4 rows selected.

Note that code tags end with [/code] not [\code].
Thanks for the Oracle version number and test case.

rajeshkr,

If you refuse to respond with feedback, "It Worked", "It didn't Work", "I found a different solution", or one of your own, people will not continue to help you. Ghosting someone after asking for help is considered very rude.
