Sometimes it’s necessary fix data on the database.
I had to fix on a Microsoft database:

      /* MSSQL syntax */
      update table_links set url  = Replace(url, '', '') where url <>''

I had to fix on a MySQL database:

      /* MySQL syntax is the same! */
      UPDATE table_links SET url =REPLACE(url, '&amp;', '&') where url<>''

The syntax is the same.
