i found a solution

  1. Backup your \wamp\bin\mysql\mysql5.6.12\data folder JUST IN CASE.

  2. left click the wampmanager icon -> MySQL -> my.ini ( to edit the mysql config file )

and add this line to the wampmysqld section [wampmysqld] (or [mysqld] if You don't have [wampmysqld])

innodb_force_recovery = 1

and then save my.ini

  1. left click the wampmanager icon -> MySQL -> Service -> restart service

give it a minute to do its recovery, then check the mysql error log again to see if it has recovered the database.

  1. left click the wampmanager icon -> MySQL -> my.ini ( to edit the mysql config file )

now remove the innodb_force_recovery = 1 parameter you previously added.
