You guys are all doing this the hard way!

Regular expressions to the rescue!

Here's a complete test:

declare

   tstr varchar2(100) := 'this contains tabs multiple spaces and single spaces';
begin

   dbms_output.put_line( tstr);
   owa_pattern.change( tstr, '\s', '', 'g');
   dbms_output.put_line( tstr);

end;
/

You may have to run $ORACLE_HOME/rdbms/admin/owacomm.sql to build the regular expression packages.

Read $ORACLE_HOME/rdbms/admin/pubpat.sql for details.

Want to know more about regular expressions? Read the perl docs on regular expressions, look
in 'Programming Perl', or if you're really hard core, get Jeffrey Friedl's book 'Mastering Regular Expressions'
