Kirti,
if the input is going to be HTML, then I have no clue how you'd do it, but if it is just a varchar2 then something like following might help ...
SELECT REPLACE( UPPER(:my_str)
,REPLACE( TRANSLATE( UPPER(:my_str)
,'123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ'
,'-----------------------------------'
)
,'-'
)
)
FROM DUAL
/
It gets more complicated for mixed case queries.

Subject: Replacing control chars
Hello Listers,
I was asked if there is any procedure that could be called from a trigger to replace (with a blank) or remove all non-printable characters from the text before inserting it in the target table? The incoming data is from a Web interface and may contain underline, bold, blink, NL characters. Target column should get characters 0-9, A-Z and a-z. The data should not be rejected.
I suggested use of 'replace', but was asked if I had anything already written to do this. And I have not.
Done anyone have anything to share?
Thanks.
