select substr( '12~34~56~78'||'~', 1, instr('12~34~56~78','~')-1 ) first_val,
substr( '12~34~56~78'||'~~', instr( '12~34~56~78'||'~~', '~') +1,
instr( '12~34~56~78'||'~~', '~', 1, 2 )-instr('12~34~56~78'||'~~','~')-1 ) second_val
from dual
FIRST_VAL SECOND_VAL
12        34        
1 rows selected
required output:
12   34   56   78
Your required output has changed significantly from your first post to now. In your first post you showed the output in rows, now you are using a technique that suggests you want columns.
For columns you can use this
WITH x as
(   select '12~34~56~78' a from dual UNION ALL
    select '~34~56~78' a from dual UNION ALL
    select '12~~56~78' a from dual UNION ALL
    select '12~34~~78' a from dual UNION ALL
    select '12~34~56~' a from dual UNION ALL
    select '~~~' a from dual UNION ALL
    select '~~~100' a from dual
SELECT
    a||'~',
    substr(a||'~',1,INSTR(a||'~','~',1,1)-1) cola,
    substr(a||'~',INSTR(a||'~','~',1,1)+1,INSTR(a||'~','~',1,2)-INSTR(a||'~','~',1,1)-1) colb,
    substr(a||'~',INSTR(a||'~','~',1,2)+1,INSTR(a||'~','~',1,3)-INSTR(a||'~','~',1,2)-1) colc,
    substr(a||'~',INSTR(a||'~','~',1,3)+1,INSTR(a,'~',1,4)-INSTR(a,'~',1,3)-1) cold
FROM
    xOr even better, the one from Kim Berg Hansen - quite a bit neater!
