I am moving one database from one computer to another computer.
I have copied the folder from Xampp > Mysql >Data > 'Database named folder' and placed in same location in new computer.
Now I am trying to access the tables of that database from new computer using PHPMYADMIN from browser and I am getting this error :
#1932 - Table 'recoverydata.assignfeedback_editpdf_quick' doesn't exist in engine
Is there any more file that I need to copy? Or what's the solution?
Using Command Line Windows:
Exporting the database
Open up a Windows command prompt.
Change the directory to the following to access the mysqldump utility.
cd \bin
Create a dump of your current mysql database or table (do not include the bracket symbols [ ] in your commands).
Run the mysqldump.exe program using the following arguments:
mysqldump.exe –e –u[username] -p[password] -h[hostname] [database name] > C:\[filename].sql
If you supplied all the arguments properly, the program will connect to your current mysql server and create a dump of your whole database in the directory you specified in your C:\ directory. There is no message that will indicate the dump has been completed, the text cursor will simply move to the next line.
Here is an example of the command line syntax:
Importing The Database :
Go to the directory that the mysql client utility is located.
cd C:\Program Files\MySQL\MySQL Server 5.5\bin
Import the dump of your database or table.
Run the mysql.exe program using the following arguments.
mysql –u[user name] -p[password] -h[hostname] [database name] < C:\[filename].sql

I'm using XAAMP and the information about database is as follows
I was trying to upload employees sample database from https://launchpad.net/test-db/ through CMD but I don't have much knowledge about mariaDB commands and all the information's on google is for mysql.
My command line for C:\xampp\mysql\bin\mysql.exe opens as below not as normal mysql.
Notice the MariaDB[<none>]>
I have set a custom password for the database in phpmyadmin for root.
What is the command line to upload the large mysql database from the folder
C:\xampp\mysql\employees_db
Actually that is very easy:
First, you need to unzip the database in C:\xampp\mysql\bin\ folder
Then, you have all the *.sql files in that folder, right?
Now, open a command line and type the following commands:
cd C:\xampp\mysql\bin\
mysql.exe -u root -p yourDatabasePassword < employees.sql
I have a backup.mysql file that I created using mysqldump.
How can I use that to restore the database? I opened the file in Sublime Text, and here is what its beginning looks like!
The dump you produced is a SQL script you can run with any tool you want. As OP from this question How do I restore a dump file from mysqldump?, if you try to restore it with MySQL Administrator or other software providing specific backup/restore functions, it can throw an error because it asks for a particular format (his own format); but if the dump has been produced correctly, you can run it with any MySQL client, for example with the command line tool :
mysql -h hostname -u username -p yourschema < ./path/to/the/script.mysql
Copy your backup.sql file to the working directory: C:\xampp\mysql\bin. (or whatever your path)
In your command prompt or terminal switch to the MySQL directory. cd c:\xampp\mysql\bin (or whatever your path)
Open the MySQL Database system mysql –h localhost –u root (or whatever your credentials)
You need to re-grant permissions: GRANT ALL ON your_db_here.* to 'root'#'localhost'; (or whatever your credentials)
You need to re-create the database: CREATE DATABASE your_db_here;
Start using the database: USE your_db_here;
Import the dump file that you created: source backup.mysql
Using DESCRIBE commands and "SELECT * FROM" commands ensure that your database has been restored properly.
Is there a way to connect to my mysql database and do sth on tables via terminal?
Yes. In your terminal start the mysql prompt using
mysql --user=user_name --password=your_password db_name
Where db_name is the name of your database and user_name and password are your username and password.
You can then run SQL statements/queries from .sql files
mysql db_name < script.sql > output.tab
Where db_name is your database name, script.sql is a file containing your script, and output.tab (optional) is a file in which to dump the output of the query
You then simply place an SQL query in a file and run it.
If you get the error mysql: command not found, this is because the mysql executable cannot be found in your system PATH. If so, you need to run the following command to add the mySQL folder to the PATH, so that OS X knows to look there for the executable
export PATH=${PATH}:/usr/local/mysql/bin
Where /usr/local/mysql is the location of your mysql installation.
You can add this to your .bash_profile file (located at ~\.bash_profile, or you can create it) in order to have it run every time you start a new terminal. Otherwise you'll have to enter it manually before using the mysql command
Once you've entered this command (or added it to .bash_profile) you can use the mysql command as above
Alternately navigate to /usr/local/mysql/bin (or the location of your mysql install) and use the command
./mysql command
Instead of
mysql command
As above (where command is the command described in the first half of this post). This runs the mysql binary directly, rather than searching for it in the PATH
I want to copy my mysql database from my computer to another computer. How can I do this?
How to copy Mysql database from one Computer to another / backup database using mysqldump
We can transfer a MySQL database from one PC to another PC using
mysqldump command.
We have to create dump file of database to transfer database from
one PC to another PC.
MySQL database is not portable database i.e. we cannot transfer it
from one PC to another PC by copying and pasting it.
We can use following method to transfer database.
Creating a dumpfile from database/ Taking backup of MySQL database:
Open command prompt.
Execute following commands to change directory
>c: “press enter”
>cd program files/MySQL/MySQL Server 5.1/ bin “press enter”
>mysqldump -u root -p database_name > database_name.sql “press enter”
Enter password: password of MySQL
Copy sql file and paste it in PC where you want to transfer database.
2. Dumping sql file into database:-
- Open MySQL command line client command prompt.
- Execute following command to create database.
create database database_name;
“press enter” Database name is must as that of your database_name.
Copy that sql file into location “c:/program files/MySQL/MySQL Server 5.1/bin”
*- Now open command prompt and execute following commands.*
>C: “press enter”
>cd program files/MySQL/MySQL Server5.1/bin “press enter”
>mysql –u root –p database_name < database_name.sql “press enter”
Your database is created on PC.
Now in MySQL command prompt check your database.

This best and the easy way is to use a db tools(SQLyog)
http://www.webyog.com/product/downloads
With this tools you can connect the 2 databases servers and just copy one database on server a to server b.

For a database named "lbry", try this:
mysqldump -u root -p lbry > dump-lbry.sql
Create a database of the same name ("lbry" in this example) on the computer to which you wish to copy the database contents
Then import it:
mysql -u root -p lbry < dump-lbry.sql
You can do by this process step-by-step using MySQL WorkBench.
Install MySQL Workbench
Connect to existing Database
Go to Navigator -> Management -> Data Export.
(this will dump queries of tables one by one in a separate folder, Workbench uses the same folder to import)
Create Database on target PC.
Connect to Target Database (would consist of 0 tables in DB)
Go to Navigator -> Management -> Data Import/Restore.
(this will use the dump folder and create tables in your target Database).
Hope this helps.
The only SAFE way to copy databases from one machine to another is to first quiesce the database (make sure no clients are modifying it), then use the mysqldump command to create a text representation of your schema and the contents of your tables. Then copy that text file over to the other machine and read it in by specifying it as the input to the mysql command.
Attempting to copy the actual mysql data directories over is asking for trouble, since they are dependent on the architecture of the machine that mysql is running on and likely on the version of mysql and whatever storage engine is in use.
This tutorial is in Ubuntu but will work on Redhat, Centos, Fedora, Suse
We can dump database, transfer it to another server, and restore it
It will show how to take care of things like modified credentials as a result and moving debain.cnf file
4 dump restore will slow down the serverHow it works
4.1 Run mysqldump on source server:this builds a MySQL executable script for the destination server.
During this time the MySQL server will queue queries
4.2 Copy dump file to the destination server
4.3 Empty destination server
4.4 Execute dump file on the destintion server
Server A(Source Server)
Server B (Destination Server)
Case 1:Server A
root#source$ mysql --defaults-file=/etc/mysql/debain.cnf
mysql>show databases;
mysql>use testdb;(The database to dump)
mysql>show tables;(To Check the tables)
mysql>^c
-- now dump the databses
root#surce$ mysql --defaults-file=/etc/mysql/debain.cnf --all-databses | gzip -c > dump.sql.gz
root#surce$ gzip -dc dump.sql.gz
To copy the files create a ssh key on the source server
root#surce$ ssh-keygen
root#surce$ cat /root/.ssh/id_rsa.pub
select and copy all the ssh key string
root#surce$ scp dump.sql.gz ubuntu#destination:
goto destination server
last step copy the contents of debain.cnf file
root#surce$ cat /etc/mysql/debain.cnf
[client]
host = localhost
user = debain-sys-maint
password = mysecret
socket = /var/run/mysqld/mysqld.sock
[mysql_upgrade]
host = localhost
user = debain-sys-maint
password = mysecret
socket = /var/run/mysqld/mysqld.sock
basedir = /usr
select all and copy this file to detination server.
Note: The sockey path can be different in your machine .use locate command to find the exact path
Case 2. Server B
drop all databses
root#destination$ echo show databases | mysql --defaults-file=/etc/mysql/debian.cnf --skip-column-names | awk '{print "drop database "$1";"}'
if this command doesnot drop databses use it with -force option
root#destination$ echo show databases | mysql --defaults-file=/etc/mysql/debian.cnf --skip-column-names | awk '{print "drop database "$1";"}' | mysql --defaults-file=/etc/mysql/debian.cnf -f
copy the ssh key on the destination server
root#destination$ echo "paste the key here" >> /home/ubuntu/.ssh/authorised_keys
goto source Server and use scp command to move the dump on the destination server
(inject the file)
root#destination$ gzip -dc /home/ubuntu/dump.sql.gz | mysql --defaults-file=/etc/mysql/debain.cnf
root#destination$ > /etc/mysql/debain.cnf
root#destination$ nano /etc/mysql/debain.cnf
paste the contents of .cnf file from source server here and save the file
:x
root#destination$ mysql --defaults-file= /etc/mysql/debain.cnf
if you get the mysql prompt then everything should be working file

I was able to restore a backup that was shared with me following this thread, specifically #jmail's answer, but, I thought that I could provide a bit more concise answer for future users. I received a dump file with a .sql extension, not a .dump extension as I would have expected.
I tried to place it in my project folder and restore it but I got error 22, referring to access privileges. I moved it to “c:/program files/MySQL/MySQL Server 5.1/bin” and then ran it by:
1) Starting MySQL in the command prompt.
2) Creating the new database that I wanted to restore to
3) Switching to the database
USE new_DB;
4) Running
source c:/program files/MySQL/MySQL Server 5.1/bin/backup.sql
I'm not sure how the backup.sql file was created but this worked for restoring it on my Windows 10 system.
mysqldump --databases dbname -hsource_server_ip -usource_server_userName -psource_server_passcode | mysql
-udest_server_user_name -pdest_server_user_passcode &
There are three general ways to invoke mysqldump:
shell> mysqldump [options] db_name [tbl_name ...]
shell> mysqldump [options] --databases db_name ...
shell> mysqldump [options] --all-databases
If you do not name any tables following db_name or if you use the --databases or --all-databases option, entire databases are dumped.
mysqldump does not dump the INFORMATION_SCHEMA database by default. MariaDB dumps the INFORMATION_SCHEMA if you name it explicitly on the command line, although currently you must also use the --skip-lock-tables option.
To see a list of the options your version of mysqldump supports, execute mysqldump --help.
I just summarize jmail's answer:
Database to SQL file at computer 1:
mysqldump --user <user name> --password <database> > <output file> for example mysqldump --user root --password movie > movie.sql
SQL file to database at computer 2:
mysql --user <user name> --password <database> < <output file> for example mysql --user root --password movie < movie.sql
I am trying to run a set of sql files with stored procedures and triggers in my windows XAMPP environment. Some suggested to me using a batch script but I do not know how to do this in windows.
Is it possible to run all these .sql files from within MySQL Workbench? How? If not, can anyone tell me how to run a batch file within windows?
Thank you.
It seems Workbench doesn't support the command "SOURCE" so the next best thing is is (at least in windows) is to run a batch job. Simply create a new .sql file and add the full path to each .sql file like so:
Create the batch file:
In windows, the batch file can be a .sql with the sql comman SOURCE which calls the other .sql files, like so:
create run.sql
SOURCE C:\xampp\htdocs\mysite\sql\procs\sp_article_delete.sql
SOURCE C:\xampp\htdocs\mysite\sql\procs\sp_article_insert.sql
SOURCE C:\xampp\htdocs\mysite\sql\procs\sp_article_load.sql
Open Command Line and CD to MySQL Folder
Open the command line, and cd to MySQL. If you are using XAMPP, the command/location should be something like:
cd C:\xampp\mysql\bin\
Execute the Batch File by pressing ENTER
Last, simply load mysql and run the batch file using the following command:
mysql -u root -h 127.0.0.1 my_database_name -vvv < C:\xampp\htdocs\mysite\sql\procs\run.sql
The execution above means the following:
mysql -u <username> -h <host> <database> -vvv < <batch_path_file_name>
-vvv shows all the queries being executed and the rows affected for debugging.
That's it. All .sql files mentioned in the run.sql file will be executed.
