db4free.net data type statistics

In response to Beat's article about "Discover "bad" use of ENUM and SET types using MySQL information_schema", here's db4free's data type statistic:

mysql> SELECT    DATA_TYPE,
    ->           COUNT(*) AS n,
    ->           ROUND(COUNT(*)
    ->                 / (SELECT COUNT(*) FROM information_schema.COLUMNS)
    ->                 * 100, 2
    ->           ) AS `%`
    -> FROM      information_schema.COLUMNS
    -> WHERE     TABLE_SCHEMA NOT LIKE 'mysql'
    -> GROUP BY  DATA_TYPE
    -> ORDER BY  n DESC;
