Oracle query cast attribute

I am trying to convert a decimal to text. Every time I try to cast, it converts the number this开发者_Python百科 way:

number:   converted: 
---------------------
0.1234    .1234

I tried using TO_CHAR, but without success.

---

Use the second format parameter of TO_CHAR function.

Try something like:

SELECT TO_CHAR(0.1234, '00000000.00') FROM DUAL
