Check for special character in a string - forum topic by Chandrashekarks

Dear Folks,
          Need to identify names with atleast one special character in TD.
For ex:   'Robert John'
              'Rama / Ram'
             '.Akbar_raj'
            'New_york_2'
           '..###'
 
Out of these need to select below names, i.e. with atleast one spec character.
              'Rama / Ram'
             '.Akbar_raj'
             'New_york_2'
            '..###'
         Please suggest an apporach. I tried to travarse through the string checking each character using WITH RECURSIVE, but could not get the result.
Regards
