Here is one way
VAR csv VARCHAR2(100)EXEC :csv := 'abc,de,fg,hij,klmn,o,pq,rst,uvw,xyz';
The query:
WITH data AS( SELECT SUBSTR(csv, INSTR(csv,',',1,LEVEL)+1,                     INSTR(csv,',',1,LEVEL+1) - INSTR(csv,',',1,LEVEL)-1 ) token    FROM ( SELECT ','||:csv||',' csv FROM SYS.DUAL ) CONNECT BY LEVEL < LENGTH(:csv)-LENGTH(REPLACE(:csv,',',''))+2 )SELECT token  FROM data;See http://projectwownow.blogspot.com/2010/02/oracle-convert-csv-string-into-rows.html
