DBRECOVER for MySQL RECOVER CASE : DELETE SQL STATEMENT

mysql> use  employees;
Database changed

mysql> show create table employees;
 
| employees | CREATE TABLE `employees` (
  `emp_no` int(11) NOT NULL,
  `birth_date` date NOT NULL,
  `first_name` varchar(14) NOT NULL,
  `last_name` varchar(16) NOT NULL,
  `gender` enum('M','F') NOT NULL,
  `hire_date` date NOT NULL,
  PRIMARY KEY (`emp_no`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1 |
 



mysql> select count(*) from employees;
+----------+
| count(*) |
+----------+
|     1000 |
+----------+
1 row in set (0.00 sec)


mysql> delete from employees;


mysql> flush table employees with read lock;
Query OK, 0 rows affected (0.01 sec)

we can directly scan the table .ibd file ,and find the deleted records:

select add .ibd from menu start
input the deleted table's ibd location
right click the ibd file , scan it
click the first page node , and input create table sql
choose the right mysql version , and page format (dynamic in most version)
select the Deleted Data Tab , then you can check deleted records and export them into MYSQLDUMP format SQL file.

You can also use conventional recovery mode in this case.
