I have a data in CSV format (comma separated values) like follows: first,second,third,fourth,fifth  I want the output as follows: column_value first second third fourth fifth The easiest way to achieve is to use a CONNECT BY clause in DUAL table and to populate the results. Here is the query: SELECT substr(str, instr(str, ',', 1, LEVEL) + 1, instr(str, ',', 1, LEVEL + 1) - instr(str, ',', 1, LEVEL) - 1) column_value FROM   ( SELECT ',' || '&mystring' || ',' str  FROM  dual) CONNECT BY LEVEL <= length(str) - length(REPLACE(str, ',')) - 1; Pass value   first,second,third,fourth,fifth to mystring.
