Hi

I have a column which has values separated by comma(,). I need to split this into multiple rows.

SELECT NOTE FROM WMS.ORDER_NOTE OR_NT, WMS.ORDERS
WHERE OR_NT.ORDER_ID = ORDERS.ORDER_ID
AND OR_NT.Note_Type  = 'CU'
AND OR_NT.Note_Code  = 'SM'
AND ORDERS.TC_ORDER_ID = '9701187158';

Note
---------
2252998,2252999,2253000

I need to split the above Note into 3 rows as below.

Note
------
2252998
2252999
2253000

Please help with the SQL query

@OP do mention the oracle version you are using, anyways
for 10g & below versions use:-

select replace(columnname,',',chr(10)) from table;

for 11g and above use unpivot

See the examples here http://lalitkumarb.com/2014/12/02/split-comma-delimited-string-into-rows-using-oracle-sql/

But, why do you store data in that fashion? It is not normalized.

How would that generate 3 rows? OP asked to split into rows:

SQL> WITH DATA AS(
  2  SELECT '2252998,2252999,2253000' str FROM dual
  3  )
  4  SELECT count(*) FROM(
  5  select replace(str,',',chr(10)) from data);

  COUNT(*)
----------
         1

SQL>

You are just replacing comma with Line feed and not generating rows.

That is not the purpose of UNPIVOT. It will convert the columns into rows, in OP's case the values are not in different columns but in the same column.

But OP has denormalized comma separated values in single column and not in different columns.
