: Find an unprintable character inside a column
Just a brief foot-note to this discussion.
The reason I selected the data, rather than attempted an automatic
correction, was that sometimes two words would be separated by ascii(10)
(forcing a line throw), and sometimes the corruption would appear
others then
return -1;
end BAD_ASCII;

Some people have requested this code, so I thought
you might as well all
have the chance to pick it to bits... Its a
function called BAD_ASCII, and
it hunts out for any ascii characters with an ascii
value of less than 32 in
a specified field. (Acknowledgments to my colleague

Actually, I was toying with the idea of writing an external
procedure that would allow me to call pcre library
(PCRE=Perl Compatible Regular Expressions) which would be nice,
but then again

not to solve this particular task -- it would be an overkill. :)

First, I created some test data with one column corrupted with a
single random character
of 0-31 replacing a random char in that column 20% of the rows of the
table.

Steve,
If you are patient, I guess that something like
where dump(problem_column) like '%target hex%'
should more or less answer your question.

Yes, exactly Stephane -
Non-printable characters like this are a proper pest in our environment, to
the extent that I have exception reports running every night looking for
them (cannot trust the users...).
I have a small PL/SQL piece of code used to detect these things, if anyone
wants it.
Peter, i would be interested in that.
can u mail it to me ?

Hello list,
I have an application that is choking on the following error,
...invalid character (Unicode: 0x19) was found in the element
content...
Does anyone know how I could go about searching for this invalid
character?
Thanks
Steve
