问题
My server got crashed today morning, so before re-installing it I just copied the folder where my localhost was running so that my databases are not lost and trust me I preserved it safely. Now its re-installed and now my localhost is working but all I want is 'employee' database back to its place. How do I get it?
I copied the folder employee and saved back to where it was but its of no use. Am still stuck.
Reminding you, I didn't export it before re-installing. So can someone tell me how to face this situation?

Ok so assuming you did do a complete backup of the old wampserver folders you can try this.
First make sure you stop all service via wampmanager
wampmanager -> Stop all Services
Now make a backup of this folder on the newly installed WAMPServer, so you can return to a vanilla, just installed state if this does not work.
move \wamp\bin\mysql\mysql5.6.17\data \wamp\bin\mysql\mysql5.6.17\data_vanilla
Now copy your backed up MySQL folder from the Previous installations files to the new install
copy \old_wamp\bin\mysql\mysql5.6.17\data \wamp\bin\mysql\mysql5.6.17\data
Now lets clear the mysql log file, so you dont get confused between old and new message in the log.
move \wamp\logs\mysql.log \wamp\logs\old.mysql.log
You should now be able to restart the MYSQL service and see if it starts up cleanly.
wampmanager -> MySQL -> Service -> Start/Resume Service
Now if the wampmanager icon goes Orange, MySQL should have started. Check the mysql error log, to see if all is well.
wampmanager -> MySQL -> MySQL log
If all is well, you can now start Apache as well.
wampmanager -> Apache -> Service -> Start/Resume Service
The wampmanager icon should go green.

You need to import it back using phpmyadmin.
- open localhost/phpmyadmin
- select database then click import
- locate the database and click go
You probably can find the data that you back up earlier in here, \wamp\bin\mysql\mysqlXX\data

when planning to recover, you should save the entire data directory . not just the folder with the database name .
refer the thread on superuser.
- go to data directory of mysql (C:\wamp\bin\mysql\mysql5.5.24\data )
- Find a file called "mysql-bin.index"
- Rename that file to "mysql-bin.index-corrupt"
- Restart the server and it will work fine, all your database will be where you left them.
or this thread on stackoverflow .
INNODB databases will have been stored in the
\wamp\bin\mysql\mysql5.6.17\ibdata1 file.There will also be info in a \wamp\bin\mysql\mysql5.6.17\data\DATA_BASE_NAME\ folder, one .frm file for each table that was in the database, but this is basically just schema information and not actual data.
If you do not have that file from the old install then your data is lost. check this super user thread for further details .
