How to split a comma-separated value to columns

Question

I have a table like this

Value   String
-------------------
1       Cleo, Smith

I want to separate the comma delimited string into two colu

Answer 1

Using instring function :)

select Value, 
       substring(String,1,instr(String," ") -1) Fname,  
       substring(String,instr(String,",") +1) Sname 
from tablename;

Used two functions,
1. substring(string, position, length) ==> returns string from positon to length
2. instr(string,pattern) ==> returns position of pattern.

If we don’t provide length argument in substring it returns until end of string
