Hi Mukta,
This is the query:
select substr(company, 1,(instr(company, ' '))) "first" , substr(company, (instr(company, ' ' )),(instr(company, ' ',2))) "second" , substr(company,instr(company, ' ',-1)) "third" from tablename;
Regards
Nand

Dear Nand,
Your query :
select substr(company, 1,(instr(company, ' '))) "first" , substr(company, (instr(company, ' ' )),(instr(company, ' ',2))) "second" , substr(company,instr(company, ' ',-1)) "third" from tablename;
will give following result:
first second third
TATA Cons Services
Wipro Chems Fertilizers
Infy Tech Services
Which coincidentally works finewith the data which we have at present in the table tablename.
The syntax for instr function works as follows:
instr(String,substring,position,occurence).
In the example discussed here, incidently data at the first and second position had equal number of characters. Hence you got it working.
Had te number of characters been different for first and second name the query would have incorrect result.
Just try out your query with following data in the table:
TATA Consultancy Services
Wipro Chems Fertilizers
Infy Tech Services
The correct query should have been:
select substr(company, 1,(instr(company, ' '))) "first",
substr(company, (instr(company, ' ' )),(instr(company, ' ',1,2))-(instr(company, ' ' ))) "second",
substr(company,instr(company, ' ',-1)) "third"
from tablename
Reards,
Vijay Mahawar.
