Re: casting question

Your fields contain spaces, because of the char(15)
datatype padding them out. The numeric conversion
routine can't handle those spaces: you will need to
use a trim function (probably rtrim() will be best) to
take them out.

You can avoid this problem if you use varchar (or
text) instead of char datatype.
