How can I access the MySQL command line with XAMPP for Windows?
Your MySQL binaries should be somewhere under your XAMPP folder. Look for a /bin folder, and you'll find the mysql.exe client around. Let's assume it is in c:\xampp\mysql\bin, then you should fireup a command prompt in this folder.
That means, fire up "cmd", and type:
cd c:\xampp\mysql\bin
mysql.exe -u root --password
If you want to use mysqldump.exe, you should also find it there.
Log into your mysql server, and start typing your commands.
On the Mac, or at least on my Mac using a default install, I accessed it at:
/Applications/xampp/xamppfiles/bin/mysql -uroot -p
For Linux:
/opt/lampp/bin/mysql -u root -p
To use just 'mysql -u root -p' command then add '/opt/lampp/bin' to the PATH of the environment variables.
To access the mysql command in Windows without manually changing directories, do this:
Go to Control Panel > System > Advanced system settings.
System Properties will appear.
Click on the 'Advanced' tab.
Click 'Environment Variables'.
Under System Variables, locate 'Path' and click Edit.
Append the path to your MySQL installation to the end of the exisiting 'Variable value'. Example:
%systemDrive%\xampp\mysql\bin\
or, if you prefer
c:\xampp\mysql\bin\
Finally, open a new command prompt to make this change take effect.
Note that MySQL's documentation on Setting Environment Variables has little to say about handling this in Windows.
Open the XAMPP control panel.
Click Shell.
Type mysql --user=your_user_name --password=your_password.
You can access the MySQL command line with XAMPP for Windows
click XAMPP icon to launch its cPanel
click on Shell button
Type this mysql -h localhost -u root and click enter
You should see all the command lines and what they do

Usage: mysql [OPTIONS] [database]
Default options are read from the following files in the given order:
C:\WINDOWS\my.ini C:\WINDOWS\my.cnf C:\my.ini C:\my.cnf C:\xampp\mysql\my.ini C:\xampp\mysql\my.cnf C:\xampp\mysql\bin\my.ini C:\xampp\mysql\bin\my.cnf
The following groups are read: mysql client client-server client-mariadb
The following options may be given as the first argument:
--print-defaults Print the program argument list and exit.
--no-defaults Don't read default options from any option file.

'rehash' to get table and field completion, but startup
and reconnecting may take a longer time. Disable with
--disable-auto-rehash.
(Defaults to on; use --skip-auto-rehash to disable.)
-A, --no-auto-rehash
No automatic rehashing. One has to use 'rehash' to get
table and field completion. This gives a quicker start of
mysql and disables rehashing on reconnect.

abort-source-on-error to 0
-G, --named-commands
Enable named commands. Named commands mean this program's
internal commands; see mysql> help . When enabled, the
named commands can be used from any line of the query,
otherwise only from the first line, before an enter.
Disable with --disable-named-commands. This option is
disabled by default.
-i, --ignore-spaces Ignore space after function names.
--init-command=name SQL Command to execute when connecting to MySQL server.
Will automatically be re-executed when reconnecting.

order of preference, my.cnf, $MYSQL_TCP_PORT,
/etc/services, built-in default (3306).
--progress-reports Get progress reports for long running commands (like
ALTER TABLE)
(Defaults to on; use --skip-progress-reports to disable.)
--prompt=name Set the mysql prompt to this value.
--protocol=name The protocol to use for connection (tcp, socket, pipe,
memory).
-q, --quick Don't cache result, print it row by row. This may slow
down the server if the output is suspended. Doesn't use
history file.
-r, --raw Write fields without conversion. Used with --batch.
--reconnect Reconnect if the connection is lost. Disable with
--disable-reconnect. This option is enabled by default.

-v, --verbose Write more. (-v -v -v gives the table output format).
-V, --version Output version information and exit.
-w, --wait Wait and retry if connection is down.
--connect-timeout=# Number of seconds before connection timeout.
--max-allowed-packet=#
The maximum packet length to send to or receive from
server.

translated to '\n'. This switch turns off both features,
and also turns off parsing of all clientcommands except
\C and DELIMITER, in non-interactive mode (for input
piped to mysql or loaded using the 'source' command).
This is necessary when processing output from mysqlbinlog
that may contain blobs.

Ajay,
The reason that you can't see the other tables is that you need to log in as 'root' in order to see them
mysql -h localhost -u root
In terminal:
cd C:\xampp\mysql\bin
mysql -h 127.0.0.1 --port=3306 -u root --password
Hit ENTER if the password is an empty string. Now you are in.
You can list all available databases, and select one using the fallowing:
SHOW DATABASES;
USE database_name_here;
SHOW TABLES;
DESC table_name_here;
SELECT * FROM table_name_here;
Remember about the ";" at the end of each SQL statement.
Windows cmd terminal is not very nice and does not support Ctrl + C, Ctrl + V (copy, paste) shortcuts. If you plan to work a lot in terminal, consider installing an alternative terminal cmd line, I use cmder terminal - Download Page
Go to /xampp/mysql/bin
and find for mysql. exe
open cmd, change the directory to mysq
after write in cmd
mysql -h localhost -u root
Xampp control panel v2.3.1
I got errors while using -h localhost
mysql -h localhost -u root
ERROR 2003 (HY000): Can't connect to MySQL server on 'localhost' (10060)
So, if you installed xampp as is and did not customize any documentroot, serverroot, etc. then the following works :-
start both the services on the xampp control panel
click shell
enter: # mysql -h 127.0.0.1 -u root
that works just fine.
Below is the logtrail:-
# mysql -h 127.0.0.1 -u root

To access MySQL in Windows you need to install the XAMPP.
Open the XAMPP Control Panel and start MySQL.
Now go to the command prompt and open
C:\>cd xampp
C:\xampp>cd MySQL
C:\xampp\mysql>cd bin
C:\xampp\mysql\bin>mysql -h localhost -u root
Your database is now ready to be executed.
I had the same issue. Fistly, thats what i have :
win 10
xampp
git bash
and i have done this to fix my problem :
go to search box(PC)
tape this environnement variable
go to 'path' click 'edit'
add this "%systemDrive%\xampp\mysql\bin\" C:\xampp\mysql\bin\
click ok
go to Git Bash and right click it and open it and run as administrator
right this on your Git Bash winpty mysql -u root if your password is empty
or winpty mysql -u root -p if you do have a password
run xampp shell to solve connect to root using pw
mysql -h localhost -u root -p and enter root pw
To access SQL via the command line we simply navigate to the xampp folder.
the folder is usually on the c:\ drive.
type: cd c:\xampp\mysql\bin then press enter.
type: in mysql -u root -p then press enter.
in the new line enter the password of the database.
type: show databases; to see all the databases that you have access to.
once you know what database you want to use type (ex. cms_database), type use cms_data or any other db_name, it should say Database changed
// Bonus Note
you shouldn't use the root user when working with databases. you would want to create a separate account (ex. cms_user) with special privileges to limit errors.
to do that type:
GRANT ALL PRIVILEGES IN cms_database.*
TO 'cms_user'#'localhost'
IDENTITIED BY 'yourpassword'
double check by using the command:
SHOW GRANT FOR 'cms_user'#localhost;
if you already have the name of the user and the specific database you wish to use, change step 2 to this.
mysql -u cms_user -p cms_database
For windows
cd\xampp\mysql\bin
mysql -u root -p
Just a simple commands for linux to open mysql :
sudo /opt/lampp/bin/mysql
to enter MySQL's command-line interface, I find this:
C:\xampp\mysql\bin\mysql -u root
for linux users who are getting
Command 'mysql' not found, but can be installed with:
sudo apt install mysql-client-core-8.0 # version 8.0.30-0ubuntu0.20.04.2, or
sudo apt install mariadb-client-core-10.3 # version 1:10.3.34-0ubuntu0.20.04.1
but have xampp installed
you can just add /opt/lampp/bin to your bashrc file and run mysql
I'm trying to connect a data modeling tool (DbSchema) to a MySQL database running in Google Cloud SQL. The cloud instance requires SSL. I've downloaded the necessary keys to my Mac and can connect through certain tools, like Sequel Pro and MySQL Workbench. However, these tools give me a way to enter the key locations into their connection windows. But, DbSchema does not - all it does is allow me to modify the connection string it uses to connect to the DB via JDBC.
What I have so far is:
jdbc:mysql://<MY IP ADDRESS>:3306?useUnicode=true&characterEncoding=UTF8&zeroDateTimeBehavior=convertToNull&useOldAliasMetadataBehavior=true&useSSL=true&verifyServerCertificate=false
This ends up giving me a password error although the PW I've used is correct. I think the problem is that JDBC isn't using the SSL keys. Is there a way to specify the locations of the SSL keys in this connection string?
This MySQL JDBC (for SSL) link may help you. Please see Setting up Client Authentication:
Once you have the client private key and certificate files you want to
use, you need to import them into a Java keystore so that they can be
used by the Java SSL library and Connector/J. The following
instructions explain how to create the keystore file:
Convert the client key and certificate files to a PKCS #12 archive:
shell> openssl pkcs12 -export -in client-cert.pem -inkey client-key.pem \
-name "mysqlclient" -passout pass:mypassword -out client-keystore.p12
Import the client key and certificate into a Java keystore:
shell> keytool -importkeystore -srckeystore client-keystore.p12 -srcstoretype pkcs12 \
-srcstorepass mypassword -destkeystore keystore -deststoretype JKS -deststorepass mypassword
Set JDBC connection properties:
clientCertificateKeyStoreUrl=file:path_to_truststore_file
clientCertificateKeyStorePassword=mypassword
I am trying to connect to a MySQL Database with SSL using a Client Certificate. I have created a truststore with the CA Certificate:
keytool -import -alias mysqlServerCACert -file ca.crt -keystore truststore
Then I created a keystore with my private key and my client certificate:
openssl pkcs12 -export -out bi.pfx -inkey bi.key -in bi.crt -certfile ca.crt
openssl x509 -outform DER -in bi.pem -out bi.der
keytool -importkeystore -file bi.der -keystore keystore -alias mysqlClientCertificate
I added useSSL=true and requireSSL=true to the jdbc URL and passed
-Djavax.net.ssl.keyStore=${db.keyStore}
-Djavax.net.ssl.keyStorePassword=${db.keyStore.pwd}
-Djavax.net.ssl.trustStore=${db.trustStore}
-Djavax.net.ssl.trustStorePassword=${db.keyStore.pwd}
to the kettle transformation from the surrounding job. I still get "Could not create connection to database server".
I can connect via SSL using the command line tool:
mysql --protocol=tcp -h myqlhost -P 3309 -u bi -p --ssl=on --ssl-ca=ca.crt --ssl-cert=bi.crt --ssl-key=bi.key db_name
Therefore my current guess is, that ther is an issue with the SSL Certificates.
Is there a way to make the MySQL JDBC Driver tell me more details, what went wrong?
Is my assumtion wrong, that kettle parameters can be used to set system properties? How do I do that instead then?
Establish Secure Connection (SSL) To AWS (RDS) Aurora / MySQL from Pentaho (PDI Kettle)
1. You need to create a new user id and Grant SSL rights to it. So this user id can connect to Aurora / MySQL only using Secured connection.
GRANT USAGE ON *.* TO 'admin'#'%' REQUIRE SSL
2. Download public RDS key (.pem fie) from AWS (http://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/CHAP_Aurora.html#Aurora.Overview.Security.SSL)
3. Downloaded file contains certificates / keys for each region.
4. Split certificates from .PEM file into different .PEM files
5. Use JDK keytool command utility to import all these PEM files into a single truststore (xyz.jks) file
a. keytool -import -alias xyz.jks -file abc1.pem -keystore truststore
6. Configure JNDI entry for your Aurora / MySQL instance in Pentaho Properties File "data-integration\simple-jndi\jdbc.properties"
a. Sample JNDI configuration
-------------------------------------------------------------------------
RDSSecured/type=javax.sql.DataSource
RDSSecured/driver=com.mysql.jdbc.Driver
RDSSecured/user=admin
RDSSecured/password=password
RDSSecured/url=jdbc:mysql://REPLACE_WITH_RDS_ENDPOINT_HERE:3306/DATABASE_NAME?verifyServerCertificate=true&useSSL=true&requireSSL=true
-------------------------------------------------------------------------
7. Make sure you copied MySQL connector jar in "lib" directory of your pentaho installation. Use connector version 5.1.21 or higher.
8.
9. Create a copy of Spoon.bat / Spoon.sh based on your operating system E.g. Spoon_With_Secured_SSL_TO_RDS.bat or Spoon_With_Secured_SSL_TO_RDS.sh
10. Now we need to pass the truststore details to Pentaho at startup, so edit the copied script and append below mentioned arguments to OPT variable
a. -Djavax.net.ssl.trustStore="FULL_PATH\xyz.jks"
b. -Djavax.net.ssl.trustStorePassword="YOUR_TRUSTSTORE_PASSWORD"
11. Use new script to start Spoon here after to establish the secure connection
12. Open/create your Job / Transformation
13. Go To View Tab - Database Connections and create new connection
a. Connection Type: MySQL
b. Access: JNDI
c. JNDI Name: RDSSecured
i. Same as name used in JDBC.properties file
14. Test Connection and you are ready…. :)
OK, here is the solution, that I have found now:
The start scripts for the various kettle tools pass parameters to the JVM by reading an environment-variable "OPT". So I have set
export OPT="-Djavax.net.ssl.keyStore=/path/to/keystore -Djavax.net.ssl.keyStorePassword=private -Djavax.net.ssl.trustStore=/path/to/truststore -Djavax.net.ssl.trustStorePassword=private"
Now the MySQL JDBC Driver finds its certificates and private key and can establish the connection.
I have a shell script that does the following
mysql -uuser -ppass -e "DROP DATABASE IF EXISTS database"
However, this brings up a prompt if you're sure you want to do that [Y/N]. I need this in a script so is there a way to force it execute? --force option in documentation talks about not stopping for errors.
EDIT: mysql client in fact does not generate prompt. It turns out I had mysqladmin client call that was generating the prompt.
It is evident that the shell script is waiting for the Y/N response and not the MySQL client.
You should be able to execute the line directly by just copying/pasting
mysql -uuser -ppass -e "DROP DATABASE IF EXISTS database"
at the Linux command prompt.
If you prefer, where this command appears, simply comment out the Y/N response from the shell script.
My next suggestion would be for you look into your my.cnf.
See if there is a [mysql] or [client] section with the following:
[mysql]
i-am-a-dummy
safe-updates
or
[client]
i-am-a-dummy
safe-updates
Those are real options: See safe-updates and i-am-a-dummy in the MySQL Documentation
UPDATE 2013-01-25 16:48 EDT
My next guess would be the Operating System. Why ???
If you are logged into Linux as root or you executed sudo, you have unquestioned rights to doing a DROP DATABASE IF EXISTS. At the OS level, mysqld would attempt to discard the folder for the database.
For example, if datadir is /var/lib/mysql and you execute DROp DATABASE IF EXISTS rolando;, mysqld will attempt to run rm -rf /var/lib/mysql/rolando.
if you are not root or sudo'd as root, I would expect the OS to echo that message. In fact, I have seen a message from the OS ask to delete a PID file when I was not logged in as root and attempted service mysql stop.
UPDATE 2013-01-25 16:54 EDT
mysqladmin does not cause prompting either, except for passwords. Here are all its options:

HEY, I STAND CORRECTED
--force does prompt for DROP DATABASE
OK I guess you located the culprit. I learned something today because I do not use mysqladmin to drop databases.
Might have to pipe the 'yes' into the command. This site offers an idea on how to do this.
yes | mysqladmin -u[username] -p[password] drop [database]
But here is another wrinkle via this post.
mysqladmin -u[username] -p[password] -f drop [database]
In general, you can pass any query to mysql from shell with -e option.
mysql -u username -ppassword -D dbname -e "DROP DATABASE"
Or you can Store your password in my.cnf but its less secure.
[client]
host = localhost
user = username.
password = password
socket = /var/lib/mysql/mysql.sock
i know how to import an sql file via the cli:
mysql -u USER -p DBNAME < dump.sql
but that's if the dump.sql file is local. how could i use a file on a remote server?
You didn't say what network access you have to the remote server.
Assuming you have SSH access to the remote server, you could pipe the results of a remote mysqldump to the mysql command. I just tested this, and it works fine:
ssh remote.com "mysqldump remotedb" | mysql localdb
I put stuff like user, password, host into .my.cnf so I'm not constantly typing them -- annoying and bad for security on multiuser systems, you are putting passwords in cleartext into your bash_history! But you can easily add the -u -p -h stuff back in on both ends if you need it:
ssh remote.com "mysqldump -u remoteuser -p'remotepass' remotedb" | mysql -u localuser -p'localpass' localdb
Finally, you can pipe through gzip to compress the data over the network:
ssh remote.com "mysqldump remotedb | gzip" | gzip -d | mysql localdb
Just thought I'd add to this as I was seriously low on space on my local VM, but if the .sql file exists already on the remote server you could do;
ssh <ip-address> "cat /path/to/db.sql" | mysql -u <user> -p<password> <dbname>
I'd use wget to either download it to a file or pipe it in.
