Is there a way how to recover deleted rows in Mysql deleted over a month ago

I am using Mysql and by mistake deleted very important details.Is there a way how to recover deleted records in Mysql?

I know this is not really what you are asking but I find it important that you know this.

The system I suggest is called soft delete. It works as follow:

1. Make a new column in your table (for ex the table people):

   ID	Name	Deleted
   1	Bob	0
   2	Frank	1
   3	Alice	0

   With 0 as undeleted and 1 as deleted in last column with the type BOOLEAN. Name and ID are respectively a NVARCHAR and an INT.

2. If you want delete a record, you don't delete it with a DELETE statement but update it like this:

   UPDATE people SET Deleted = 1 WHERE ID = 1
   

   Result:

   ID	Name	Deleted
   1	Bob	1
   2	Frank	1
   3	Alice	0

   You know ID's 1 and 2 are deleted because the boolean in column Deleted is on 1. Alice with ID 3 is not deleted because the boolean is on 0.

The pro of this system is that you can recover data with only one statement!

UPDATE people SET Deleted = 0 WHERE Deleted = 1

Result:

Now all record are recovered because the boolean in column Deleted is on 0.

If you use DELETE statement, it is impossible to recover all records! They are deleted for always and you can never recover it if you are using the DELETE statements. You can only use a backup file for recover it but has also contra's like:

• It's an old backup file,
• I've forget to make one,
• I don't know how you can make it,
• I've lost it,
• ...

By soft delete you change only one column and you have your data back.

Edit:
The contra of the system is that (like you have said) the data is not exactly remove from your database. It's only a column you change from 0 to 1. But if you know that you can make money from data... is this another story.

If you want to delete it exactly you can use a DELETE statement.
