Home -> Community -> Mailing Lists -> Oracle-L -> Re: Conversion of a varchar2 to a number
David,
This is my suggestion :
(vrr is the table with w_char varchar2(10))
select * from vrr;
W_CHAR
select w_char, to_number(w_char)
from vrr
where length(w_char) =
length(translate(upper(w_char),'0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ',
'0123456789'))
/
W_CHAR TO_NUMBER(W_CHAR)
-------------------- ----------------- 123 123
You may have to modify the code to include the ( , ) and - characters that u may have in a phone number format.
Let me know if this works for u...
Regards
