I am using wamp server. I have made some project and there are some also databases.
I install new window and then i install wamp server in same drive where the wamp sever is.
After installing wamp my project file in "www" are present as pervious but in phpMyAdmin there is only database name is present when I open it there is no table. where the tables gone ???
I check the "wamp>mysql>data". Here the files are present of that tables but it does not show in the phpmyadmin.
I need these tables how can I recover it.
I suggest to you ,use the feature in windows called "restore previous versions" .
Right click the Wamp folder click Restore previous versions and select the most recent date you know it was working,it maybe work for you.
I assume you mean that you did ...
Install new windows.
Install WampServer on new windows
Copy my old\wamp\www folder to the new install
Copy the subfolders in \wamp\bin\mysql\mysql{version}\data to the new install
If this is correct, then dont forget to copy the contents of \wamp\bin\mysql\mysql{version}\data as well. If you are using INNODB database the actual data lives in the ibdata1 file in that folder.

I just install a fresh copy of WAMP, and I want to import couple of databases from the old one to the new one, so I entered to the old mysql data directory C:\wamp-old\bin\mysql\mysql5.7.14\data, and copy the relevant databases there to the new data directory. But when I try to access the tables in phpmyadmin, I get a message saying that the tables aren't exists, but they do:
What am I missing?
You forgot to copy the ibdata file.
I did it successfully just now:
make a copy of wamp folder (wamp-old)
uninstall the wamp
install the new wamp (overwrite all the files if u were asked)
start the wamp
ck the localhost and phpmyadmin
copy your databases from the old-wamp only from C:\wamp-old\bin\mysql\mysql5.7.14\data and paste to the same location in new wamp
then copy and paste ibdata file from the above path and replace in new one.
You are done!
you can not restore databases like this way,
Please follow this steps to restore the databases from old to one,
Backup all the databases using phpmyadmin (Export Feature)
Install the fresh XAMPP
Restore the all the databases using phpmyadmin (Import Feature)
In my case the mySQL version of my old Wamp installation (5.7.26) was very different from the one in my new Wamp installation (8.0.21), so nothing from the solutions here worked for me.
I downloaded the old version of mysql from https://wampserver.aviatechno.net/#mysql_versions , installed it and replaced the hole ‘data’ folder with my old one.
Now from Wamp\MySQL\Version menu I can choose the old version and all my old databases are working fine.
You can leave that working version of mySQL or export the databases and import them to the new mySQL version.
Stop the Service (because it will complain for a file opened by another app) then Just copy and paste the ENTIRE (...\data) file from old installation folder backup to the new installation by overwirting the existing new installation file.
Finally, start the service.
I was working with XAMPP 1.8.3-3 on OS X Mavericks. After upgrading to Yosemite Mysql server stopped working. And an upgrade to XAMPP 1.8.3-5 fixed the problem and mysql server starts working.
Now the entire database list is showing on phpmyadmin, but no access to the tables. Its showing “#1146 - Table ‘DB_NAME.TABLE_NAME’ doesn’t exist”.
Unfortunately I don't have any DB backup!
I have the entire XAMPP folder backup. So how I can able to retrieve the mysql tables?
just type /Applications/XAMPP/xamppfiles/bin/mysql.server start
in terminal then start xampp
you can restore if you have all the mysql folders from XAMPP folder. (check /XAMPP/xamppfiles/var/mysql in backup)
if you have var/mysql folder, open and look for database names you had earlier.
there is a separate folder for each database you had earlier. open the folder and it will contain lots of files with table names.
if your old table engine is InnoDB you will see 2 files. with .frm and .ibd extensions.
or if you had MyISM it will contain three file per table which has .frm, .MYD and .MYI extensions.
after you verify you have all the required files in backup, you can start restoring them.
stop mysql
copy required database folder completely and paste it to currently installed folder. (/Applications/XAMPP/xamppfiles/var/mysql/)
start mysql
to restore web files, open htdocs folder in backup and copy required site folder to currentely xampp installed htdocs folder.
This solution worked for me. Good Luck !
Do a clean install. See my answer for my own question. xampp mysql server not starting. The bad part is that I'm not sure if it will save your database the way I explained. What you might try is going to xampp > xamppfiles > var > mysql > 'your database name' and making a copy of the database folder on your desktop and moving it back once you reinstall it. I tried and I think it might have worked had I changed the file permissions. You can also try experimenting to see if it preserves the database if you do this. I would do some serious testing if you really want to save your database before doing this.
I screwed up the config files for Apache
I reinstalled(without any uninstall) the WAMP in same folder but instead of 2.4 I did 2.5, so WAMP failed gloriously afterward.
I can not access WAMP anymore, so I can not backup my DBs from PHPMyAdmin (any hint about how to do backup in this senario will be helpful)
I copy the whole /wamp folder content (after screwed up the install).
I installed the 2.4 version Now WAMP running All DBs are still listed there But when I accesss two of the WP sites, they ask me to create a new site title, but not allow me to set username (says"User(s) already exists.").
Now I went back PHPmyAdmin and found the db for that WP site is EMPTY
I wonder how can I retrieve the good database information stored in that original /wamp folder backup, somehow, transfer into the new one, so that the db table that is EMPTY will populate with the original data again?
Thank You
Probably the safest way to recover is to:
Stop WAMPServer.
Copy the old MySQL folders to the new install of WAMPServer
So thats
copy \wamp_backup\bin\mysql\mysql(old version) to \wamp\bin\mysql\
Start WAMPServer again.
Now in the menu
Wampserver -> MySQL -> Version
you should see you old mysql version and the new one that came with the new install as well.
Switch to the old version by clicking on the old version number on that menu.
Wamp shoud now switch from the new MySQL to the old. Wait for WAMPServer to go green again.
Check the Mysql error log, to see if anything unpleasant has happened, if not,
You can then use phpmyadmin, or whatever tool you are used to to backup your missing databases.
Then switch back to the new version of MySQL and restore the databases to this version of mysql.
I hope this goes smoothly, it should.
Can someone help me out of this error?
I had old version of wamp, because of virus I have formatted my computer, although I have backed-up the "wamp\bin\MySQL\mysql5.5.24\data". Now, I have installed the new version of "WAMP". It comes with the new "mysal5.6.12\data", I have tried to copy "data" in that folder but it not works.
My entire database which I have backed-up, is not working so, please somebody help me how to do that.
Uninstall your current WAMP server.
Install your previous version of WAMP server.
Import your database from your data file.
Export your whole database as SQL.
Install new version of WAMP server.
Import your new SQL to new WAMP server.
I got this fixed up after some troubles.
You can reinstall all your data by copying over the contents from the old wamp server to the new one
Just check your new mysql version and into wamp/bin/your version/data backup that folder into /backups
Then copy over wamp/bin/your old version/data to the folder above wamp/bin/your version/data
This should load wamp server but with an orange icon
Go to the backups folder and copy the mysql, perfomance schema and test folders into the new
That should work out
If you have troubles let me know
I had few databases related to different projects in the WAMP. I don't know what happened, Today, when I go to PhpMyAdmin, I was just able to see the default databases and rest of my databases are not showing and even the php code related to those databases are throwing database not found errors. But when I go to "D:\wamp\bin\mysql\mysql5.1.30\data" the folders with my DB names are there. But not sure how to restore those DBs and I don't have any backup of the DB, Can any one help me how to restore them?
You can copy these file to another location and reinstall the same WAMP version after installtation copy them back to original location.
Please note that your WAMP version should be same, because if the version will change then mysql version will also be change.
Another method is to utilise Window's "Restore previous versions" feature. Right click the wamp folder (usually in C:\, click Restore previous versions and select the most recent date you know it was working.
Note: This will also revert mysql data - so you'll lose any changes after the date you select, but I have used this in the past when I needed to get my whole wamp system back to a working state when something had broken it.
Have you checked my.ini file? Just find datadir it should refer to db folder (e.g datadir=D:/Wamp/bin/mysql/mysql5.1.30/data) - goodluck :)
Copy the complete data folder from old wamp mysql folder to new mysql folder and then inside data folder change the name of the file mysql-bin.index to mysql-bin.index-corrupt. Then restart WAMP. That's all.
reinstall Wamp Server that must be same version. After reinstall if wamp show red icon 1. go to wamp -> apache -> services ->test port 80.
if its available . then apache -> services -> install services.
2. mysql-> services -> install services.
after that restart wamp..
100% work
Copy data folder and reinstall same version of WAMP.
Once installation is completed, go to data folder: inside replace only ibdata1 file from existing folder.
After starting WAMP, check phpmyadmin: you'll get all database and tables with data.
