    Hi

    You need to use instr and substr functions

    select substr('123-23-3456',1,INSTR('123-23-3456','-',1,1)-1) from dual;

    select substr('123-23-3456',INSTR('123-23-3456','-',1,1)+1,
    INSTR('123-23-3456','-',-2,1)-INSTR('123-23-3456','-',1,1)-1)
    from dual

    and so on

    regards

    You could also use
    select
    substr(phno,1,3) first_field,
    substr(phno,5,2) second_field,
    substr(phno,7,5) third__field
    from table_name
