title: Remove dots and commas from numbers in MySQL database
body: <p>In a Wordpress MySQL database, in <code>wp_postmeta table</code>, there are most rows with <code>meta_key='price'</code> and with <code>meta_value='XXX'</code> where XXX is a number.
   The meta_value is a long text field. The numbers stored in it have a different shape some are stored with a dot, meaning thousand (10.000 means ten thousand) others are stored with a comma, meaning hundredth (10,00 means ten).
   How to remove dots and comma so to have a pure number, without hundredth? In other words, 100.000 should be 100000 and 10,00 should be 10
   Thank you in advance for your answers!</p>
