Recover MySQL database from data folder without ibdata1 from ibd files
MyISAM

For a MyISAM table mydb.mytable, you should have three files


\bin\mysql\mysql5.6.12\data\mydb\mytable.frm
\bin\mysql\mysql5.6.12\data\mydb\mytable.MYD
\bin\mysql\mysql5.6.12\data\mydb\mytable.MYI


They should already be accessible as a table since each file contains needed data, metadata, and index info. Collectively, they form the table. There are no external storage engine mecahnisms to access.

InnoDB

Take a look at this Pictorial Representation of InnoDB



The only thing that attaches ibdata1 to the .ibd files is the data dictionary.

Your mission, should you decide to accept it, is to create each table and swap in the .ibd

Before you do anything, make a full copy of "\bin\mysql\mysql5.6.12\data" to another 

Here is a sample

Suppose you have a database mydb with the table mytable. This means


You have the folder \bin\mysql\mysql5.6.12\data\mydb
Inside that folder, you have


mytable.frm
mytable.ibd



You need the .frm. If you look at my post How can extract the table schema from just the .frm file?, you can download a MySQL utility that can generate the SQL needed to create the table.

You should now do the following


Move mytable.ibd to \bin\mysql\mysql5.6.12\data
Run the SQL to create the InnoDB table
Login to mysql and run ALTER TABLE mydb.mytable DISCARD TABLESPACE; (This will delete \bin\mysql\mysql5.6.12\data\mydb\mytable.ibd)
Copy \bin\mysql\mysql5.6.12\data\mytable.ibd into \bin\mysql\mysql5.6.12\data\mydb
Login to mysql and run ALTER TABLE mydb.mytable IMPORT TABLESPACE; (This will register \bin\mysql\mysql5.6.12\data\mydb\mytable.ibd into the data dictionary)


After this, the table mydb.mytable should be fully accessible. You can test that accessibility by simply running:

SELECT * FROM mydb.mytable LIMIT 10;


Give it a Try !!!
