Oracle RegExp to find a row with a special character...

Hello,

I have a problem with an application that appears to be data driven. It looks like there must be a special character in a field in the query for the application that is causing an error in the application.

Can someone help me write a regular expression query to find all rows that include special characters?

Something like...

Select * from
(select upper(chr(300))||'0' a from dual)
where regexp_like(a,'[^a-zA-Z0-9\-\@\<\>]');

I'm not really sure what I'm looking for. I'm hunting for a goofy character that's breaking the app.

Have you already tried Posix character classes (like "[:cntrl:]"), as shown here for instance?!

what you have should work

here's another method, this will let you search through individual characters causing the problem

SELECT *
  FROM (SELECT a, SUBSTR(a, COLUMN_VALUE, 1) ch
          FROM yourtable,
               TABLE(
                   (    SELECT COLLECT(LEVEL)
                          FROM DUAL
                    CONNECT BY LEVEL <= LENGTH(yourtable.a))
               ))
