Great number formatting trick
An excellent use of Oracle’s inbuilt formatting function – much simpler than parsing the input and multiple concatenation operators:
SELECT TO_CHAR(0408211234, 'FM0000G000G000','nls_numeric_characters=.-') phone from dual;
PHONE
-------------
0408-211-234
SSN formatting with TO_CHAR
Hi Jeffrey
Your formatting trick is very clear and fine, but what to do if I want to have more complex mask based on various input strings ;)
Please check out my query

Hi vkamys,
I would probably use a CASE structure to select the appropriate format mask depending on the input.
