mysqldump command not working? - mysql

I am using mysqldump to take backup of my database, but the command is not working..
the command i am using is mysqldump -u root dbname> 'c:\backupdatafolder\backup.sql'
i am running this command in MySQL cli but not running,..is there any thing wrong in the command?

You are supposed to run that on the command line of your operating system not on the MySQL CLI.
cd to the bin folder of MySQL first, something like C:\mysql\bin or wherever your MySQL is installed on

If the mysqldump can not be identified by your CMD prompt (I believe you are using Windows), then you first have to go to the bin folder where this command can be found. In my case, the path is "C:\wamp\bin\mysql\mysql5.5.24\bin", it would be more or less the same path for you. After that open your CMD prompt and go to this path by command "cd C:\wamp\bin\mysql\mysql5.5.24\bin". Now you should run your mysqldump command for taking the backup as you have been trying. Hope this helps!

Trying to edit the my.cnf file in mysql and it does not work

I'm attempting to use cat /etc/my.cnf in mysql but when I do this, it just shows -> wanting me to keep putting in inputs.
However, when I put a semicolon at the end.
cat /etc/my.cnf;
it throws an error.
How can I edit the /etc/my.cnf file?
I'm running this on terminal on a Mac and I got into the mysql server by using the command
sudo /usr/local/mysql/bin/mysql -u root
.
Are you typing this in to the mysql> shell? If so, UNIX-shell commands like cat won't do anything useful. These aren't commands MySQL knows how to deal with.
You need to run these in a plain Terminal (shell) window outside of MySQL.
By default most systems launch the bash shell which has access to command-line tools like vi, etc. The MySQL shell is SQL only.
It seems you are trying to edit MySQL configuration from MySQL shell but that will not work. Follow below
steps to edit the file
Open terminal and type below command to open mysql config file in textedit
sudo nano /etc/my.cnf
Save the file and restart MySQL
Hope this helps you

Uploading large files to Mariadb from cmd

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

Mysql command not found in OS X 10.7

I cant get my mysql to start on os x 10.7. It is located in /usr/local/mysql/bin/mysql
I get command not found when I type mysql --version in the terminal.
I tried this can't access mysql from command line mac but still get command not found. I tried installing mysql with the dmg and i have tried to install it through homebrew and I cant get it to work. When I try to start mysql with homebrew I get MySQL won't start
This is my $PATH:
/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin:/usr/local/git/bin:/Users/Victoria/bin:/usr/local//usr/local/mysql/bin/private/var/mysql/private/var/mysql/bin
This is the problem with your $PATH:
/usr/local//usr/local/mysql/bin/private/var/mysql/private/var/mysql/bin.
$PATH is where the shell searches for command files. Folders to search in need to be separated with a colon. And so you want /usr/local/mysql/bin/ in your path but instead it searches in /usr/local//usr/local/mysql/bin/private/var/mysql/private/var/mysql/bin, which probably doesn't exist.
Instead you want ${PATH}:/usr/local/mysql/bin.
So do export PATH=${PATH}:/usr/local/mysql/bin.
If you want this to be run every time you open terminal put it in the file .bash_profile, which is run when Terminal opens.
One alternative way is creating soft link in /usr/local/bin
ln -s /usr/local/mysql/bin/mysql /usr/local/bin/mysql
But if you need other executables like mysqldump, you will need to create soft link for them.
I faced the same issue, and finally i got a solution. Please go through with the below steps, if you are using MAMP.
Start MAMP or MAMP PRO
Start the server
Open Terminal (Applications -> Utilities)
Type in: (one line)

 /Applications/MAMP/Library/bin/mysql --host=localhost -uroot -proot
This works for me.
If you installed MySQL Server and you still get
mysql -u root -p command not found
You're most likely experiencing this because you have an older mac version.
Try this:
in the home directory in terminal open -t .bash_profile
paste export PATH=${PATH}:/usr/local/mysql/bin/ inside and save it
instead of writing mysql -u root -p paste the following in your terminal:
/usr/local/mysql/bin/mysql -u root -p
Or use Alias instead of writing the full path
alias mysql=/usr/local/mysql/bin/mysql
Enter your password. Now you're in.
You have to set PATH for mysql in your .bashrc file using following:
export PATH=$PATH:/usr/local/mysql/bin
But If you are using oh my zsh then you have to add path inside .zshrc file.
Your PATH might not setup. Go to terminal and type:
echo 'export PATH="/usr/local/mysql/bin:$PATH"' >> ~/.bash_profile
Essentially, this allows you to access mysql from anywhere.
Type cat .bash_profile to check the PATH has been setup.
Check mysql version now: mysql --version
If this still doesn't work, close the terminal and reopen. Check the version now, it should work. Good luck!
Use these two commands in your terminal
alias mysql=/usr/local/mysql/bin/mysql
mysql --user=root -p
Then it will ask you to enter password of your user pc
Enter password:
I have tried a lot of the suggestions on SO but this is the one that actually worked for me:
sudo sh -c 'echo /usr/local/mysql/bin > /etc/paths.d/mysql'
then you type
mysql
It will prompt you to enter your password.
Add the following lines in bash_profile:
alias startmysql='sudo /usr/local/mysql/support-files/mysql.server start'
alias stopmysql='sudo /usr/local/mysql/support-files/mysql.server stop'
and save the bash_profile.
Now, in the terminal start and stop the mysql server using the following commands:
startmysql //to start mysql server
and
stopmysql //to stop mysql server
If you are using terminal you will want to add the following to ./bash_profile
export PATH="/usr/local/mysql/bin:$PATH"
If you are using zsh, you will want to add the above line to your ~/.zshrc
With MAMP
Locate mysql usually at /Applications/MAMP/Library/bin/mysql
sudo vi /etc/paths
Add this path to file /Applications/MAMP/Library/bin
:wq (Save and quit file)
Close Terminal windows
Reopen Terminal and type mysql and it should work
I installed MAMP and phpmyadmin was working.
But cannot find /usr/local/bin/mysql
This fixed it
sudo ln -s /Applications/MAMP/Library/bin/mysql /usr/local/bin/mysql
in terminal do:
vi ~/.bash_profile
And add this line:
export PATH=${PATH}:/usr/local/mysql/bin
and the type this in terminal:
mysql -u [username] -p [password]
Maybe I'll help someone else. None of the above answers worked for Catalina. Finally, this solved the problem
echo 'export PATH="/usr/local/opt/mysql#5.7/bin:$PATH"' >> /Users/$(whoami)/.bash_profile
Of course, you have to change for the version of mysql you have installed
May be i will help out some of you that even though if you are unable to open mysql from terminal after trying changing path in .bash_profile
then you always found the error "MYSQL not found"
hence you can use the following command directly it will ask for your password and sql bash is opened
/usr/local/mysql/bin/mysql -u root -p
I had same issue after installing mariadb via HomeBrew, brew doctor suggested to run brew link mariadb - which fixed the issue.
It is possible you are using zsh instead of bash then you have to enter the above mentioned commands in .zshenv instead of .bash_profile

How to use Sql from DOS prompt

Hi I have installed MySQL from oracle website, but did not get a "MySQL Command Line" option under MySQL in Programs menu.
So I looked up on this site how to execute sql queries from DOS command prompt.
I found an answer on this site that advised to type in something like: sql root u- p- etc. but this does not work.
Can anyone advise me the syntax to use to go into sql from DOS, or direct me to the answer described above (I cannot locate it)
I use Windows 7 and downloaded the ODBC driver, too.
Many thanks.
Unless MySQL's bin directory is in your PATH variable, you will need to either be in the directory, or write an absolute path to it to execute.
Try something like this (depending on your installation):
cd "C:\Program Files\MySQL\MySQL Server 5.5\bin"
mysql -uroot
Alternatively, you could type this directly:
"C:\Program Files\MySQL\MySQL Server 5.5\bin\mysql.exe" -uroot
cd/
cd wamp
cd bin
cd mysql
cd mysql5.0.51b
#################################
note use your own version of mysql, mine is 5.0.51b
########################################
cd bin
mysql -h localhost -u root -p
////////////////////////////////
note -p that is if u use a password
////////////////////////////////////////
after this line of codes you have this
welcome note telling you the server version of mysql and your connection id
If you navigate to the bin directory of the program you just installed then type "mysql.exe"
Have a look at this guide if you get stuck with the commands
Determine the path of your MySQL installation, and add it to PATH environment variable.
SET PATH=%PATH%;C:\MySQL\bin
The above example assumes MySQL to be installed in C:\MySQL directory.
Once path is set, then you can directly execute
mysql -u root
Which logs into MySQL as root user. The -p flag can be used if password is required
It is required to execute SET PATH every time, hence you may make a batch file.

How can I run multiple Stored Procedures Files & Triggers (.sql) From MySQL Workbench

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.
