What's wrong with my procedure?

Question

I have written a stored procedure that takes a column name (or a partial column name) as a parameter, and lists of all the tables in the database that have a column name like that.
It's not working. It doesn't return a list of tables and columns like it should. It returns nothing. Here's the procedure:
=======================================
set serveroutput on
CREATE OR REPLACE PROCEDURE col_find(p_col_text VARCHAR2) IS
BEGIN
     DECLARE     CURSOR cur1 IS
          select table_name, column_name
          from all_tab_columns
          where lower(column_name) = lower('%p_col_text%')
     BEGIN
          for rec1 in cur1
          loop
               dbms_output.put_line(rec1.table_name || '.' || rec1.column_name);
          end loop;
     EXCEPTION when others then
          dbms_output.put_line('error');
     END;
END;
show errors;
quit;
=======================================
I have found that having this type of helper procedure around is a great time-saver. I have more experience in Sybase than in Oracle, and this procedure is very simple to write in Sybase. Does anybody see what my problem is?

Thanks for the help! But it's still coming back with nothing. Here's the updated procedure:
set serveroutput on
CREATE OR REPLACE PROCEDURE col_find(p_col_text VARCHAR2) IS
BEGIN
     DECLARE     CURSOR cur1 IS
          select table_name, column_name
          from all_tab_columns
          where lower(column_name) like lower('%' || p_col_text || '%')
     BEGIN
          for rec1 in cur1
          loop
               dbms_output.put_line(rec1.table_name || '.' || rec1.column_name);
          end loop;
     EXCEPTION when others then
          dbms_output.put_line('error');
     END;
END;
show errors;
quit;
