Point In Time recovery on Mysql Can someone please advise best methods to do a mysql PITR from binary logs that are saved in MIXED format. 

I am finding it difficult to identify the wrong queries that executed to avoid from restore process using mysqlbinlog tool.

When you inspect the binary log add -vvv to mysqlbinlog. It will show an effective query that corresponds to a binlog event.
