Modifying the code to search case-insensitively using a LIKE query instead of finding exact matches...

DECLARE
  match_count INTEGER;
  -- Type the owner of the tables you want to search.
  v_owner VARCHAR2(255) :='USER';
  -- Type the data type you're looking for (in CAPS). Examples include: VARCHAR2, NUMBER, etc.
  v_data_type VARCHAR2(255) :='VARCHAR2';
  -- Type the string you are looking for.
  v_search_string VARCHAR2(4000) :='Test';
BEGIN
  dbms_output.put_line( 'Starting the search...' );
  FOR t IN (SELECT table_name, column_name FROM all_tab_cols where owner=v_owner and data_type = v_data_type) LOOP
    EXECUTE IMMEDIATE 
    'SELECT COUNT(*) FROM '||t.table_name||' WHERE LOWER('||t.column_name||') LIKE :1'
    INTO match_count
    USING LOWER('%'||v_search_string||'%');
    IF match_count > 0 THEN
      dbms_output.put_line( t.table_name ||' '||t.column_name||' '||match_count );
    END IF;
  END LOOP;
END;
