I have MySQL 5.7 Community installed on Win10 and I have been using it with MySQL Workbench. Now I want to set up a replication slave and from what I found this is not possible using Workbench.
That means I have to use the Shell. According to the MySQL docs I open the Windows PowerShell (as I understand “your command interpreter”) and type the name of my database.
so the line in the PowerShell looks like this:
PS C:> mysql my_database
What I get is: “mysql: the name ‘mysql’ was not recognized as the name of a Cmdlet, a function …” (this is my translation). I tried it with the path to where MySQL is installed but same output. Where is my mistake? What is missing? Would be happy if someone could give me a hint! Thanks!
You need to set mysql in your windows environment variables to use the command "mysql" in your terminal. You could also use the full path in your terminal, but it's annoying and bad for scripting

How do I install MySQL Workbench properly? Can't connect to the SQLTools extension in VSCode.I'm new to the database scene, and can't seem to grasp how to create a successful SQL server that I can use to manipulate data. But nothing I'm doing seems to work.
Should I use Gitbash to access the terminal? I tried using my password to make a new query but it wouldn't work on the workbench. I don't know how to start the SQL server in addition to not knowing how to properly change the profile for the Workbench from a previous account. A new developer, such as myself, would appreciate any insight!
So that's really simple just install the mysql community server installer using this link https://dev.mysql.com/downloads/mysql/
Make sure to select the server only in the setup during installation if you are going to be using VS code as the client to manipulate sql queries
Then once that is done copy the bin path location from the mysql file directory (which is usually in the program files on your \C: drive on your computer) to the environment variables on your computer so that you can access mysql from the command line
Once that is done you can initialise a database from the normal command line but first type mysql -u root -p to start mysql in the command line
Then download the sql tools extension on vs code and create the database that wish
In mysql5.X database on Linux the command system or ! can be used to run bash command from database command line.
Are there equivalent commands as system or ! in mysql5.X database for Windows?
Linux:
mysql> !ifconig
Windows:
mysql> !ipconfig
The Windows command does not work!
In mysql5.X database (for Linux), command "system" or "!" can be used to run bash command from database command Linux.
You misunderstand.
This is not SQL command. This is command-line client command. And it will work only in CLI or another client which supports this command. It will NOT work if you try to send in to MySQL server directly by any technique.
Is there a equivalent command as "system" or "!" in mysql5.X database (for Windows)?
If used CLI version supports this command then it will work otherwise no. This not depends on MySQL server version.
Windows is not the same operating system, and as such the names of the tools internally are, in many cases, completely different, like ls vs. dir.
ipconfig is a Linux thing but it's also not necessarily a given that it'll be present. On more modern distributions the ip command is becoming the default. That's to say you'll need to lookup what the command you're going to run is, and verify that with testing.
You'll need to run the command appropriate for the environment you're running on, whatever that is.
That being said, running shell commands inside of the mysql> shell is highly irregular and should be a last resort. Doing it can be viewed as highly suspicious and may be restricted.
I wanted to know how I can run a .sql file which contains several queries in powershell
What I need is that through the command console of powershell, execute this .sql file and start creating the db with its respective tables from the querys that has this file, I understand that in linux I can do it, but I would like to know how to do it in powershell
from now on thanks
The powershell command looks like this
C:\> cmd.exe /c "C:\Program Files\MySQL\MySQL Server 8.0\bin\mysql.exe -u root -p password ]schema_name} < DataBase72.sql"
there are more Options for mysql.exe
Without getting into the specifics, there are two general ways to do this:
Remember there's a reason it's named PowerShell: it's also a full command line shell. This means you can connect to MySql the same way as in other shells, using the same tools provided by the database (ie: mysql.exe, mysql-cli, etc)
Powershell can use .Net libraries, including the same .Net libraries used for connecting to MySql from a C# or VB.Net program. If Connector/Net is available on the system, or if you can install it for the version of .Net available to you, you can create and use these ADO.Net objects from PowerShell code.
Is there any nice command line MySQL client for windows? I mean a single exe that allows connecting and running a sample query. I've googled and only could find big graphical environments like toad or mysql workbench. I need only a simple command line tool, where can I download sth like this?
EDIT: I don't want to install the whole MySQL package on my PC. I know it's inside the mysql package but how do I download only this cmd line client. Because i don't need anything else.
When you go to the MySQL download page, choose the platform "Microsoft Windows". Then download the "Windows (x86, xx-bit), ZIP Archive" (be sure to select the one with size over 140M.
The binaries will be in the "bin" folder.
I understand that this is not just the client binaries, but at least you don't have to install and setup the entire server.
mysql.exe can do just that....
To connect,
mysql -u root -p (press enter)
It should prompt you to enter root password (u = username, p = password)
Then you can use SQL database commands to do pretty much anything....
You can choose only install the client during server install. The website only offers to let you download the full installer (grab whatever version you want from http://www.mysql.com/downloads/mysql/).
In the install wizard, when prompted for installation type (typical, minimal, custom), choose 'Custom'. On the next screen, select to NOT install the server, and proceed with the rest of the install as normal.
When you're done, you should see just the relevant client programs (mysql, mysqldump, etc) in C:\Program Files\MySQL..\bin
Its pretty simple. I saved the mysql community server in my D:\ drive. Hence this is how i did it.
Goto D:\mysql-5.7.18-winx64\bin and in the address bar type cmd and press enter, so command prompt will open. Now if you're using it for the first time type as mysql -u root -ppress enter. Then it will ask for password, again press enter. Thats it you are connected to the mysql server.
Before this make sure wamp or xampp any of the local server is running because i couldn't able to connect to mysql wihthout xampp running.
Happy Coding.
You can also download MySql workbench (31Mo) which includes mysql.exe and mysqldump.exe.
I successfully tested this when i had to run Perl scripts using DBD:MySql module to run SQL statements against a distant MySql db.
You can access mySQL in command line just by typing:
C:\www\mysql\bin> mysql -u root -p
After which you can type sql commands normally such as:
mysql> SHOW DATABASES;
Here, I am assuming you mySQL installation directory is C:\www\mysql.
I have similar requirement where I need a MySQL client but not server (running in a virtual machine and don't want any additional overhead) and for me the easiest thing was to install MySQL community server taking typical installation options but NOT configure the server, so it never starts, never runs. Added C:\Program Files (x86)\MySQL\MySQL Server 5.5\bin to system path environment variable and I'm able to use the MySQL command line client mssql.exe and mysqladmin.exe programs.
If you are looking for tools like the the mysql and mysqldump command line client for Windows for versions around mysql Ver 14.14 Distrib 5.6.13, for Win32 (x86) it seems to be in HOMEDRIVE:\Program Files (x86)\MySQL\MySQL Workbench version
This directory is also not placed in the path by default so you will need to add it to your PATH environment variable before you can easily run it from the command prompt.
Also, there is a mysql utilities console but it does not work for my needs. Below is a list of the capabilities on the mysql utilities console in case it works for you:

mysql.exe is included in mysql package. You don't have to install anything additionally.
download the mysql-5.0.23-win32.zip (this is the smallest possible one) from archived versions in mysql.com website
cut and paste the installation in c drive as mysql folder
then install then follow instructions as per this page:
https://cyleft.wordpress.com/2008/07/20/fixing-mysql-service-could-not-start-1067-errors/
For Windows users:
1.Install the full version of MYSQL
2.On the Windows 10 start button click on search and type in MySQL
3. Select the MYSQL Command Line Client 5.5 (I am using version 5.5)
4. go ahead and run your sql queries/
5. to exit type \q or quit
In oracle database, command "host" can be used to run bash command from database command window. Is there a equivalent command as "host" in mySql?
You can use the system command.
system command, \! command
Executes the given command using your
default command interpreter.
The system command works only in Unix.
Example:
system ls -l
As an additional tweak, on most "'nix" systems you can actually do something like this:
mysql> system bash
And have the entire terminal at your disposal. This is particularly effective if you're doing code work in the terminal that interfaces with MySQL; from the shell, typing "exit" will take you back into the MySQL monitor/client, so you can go back and forth quite easily.
Obviously, other shells ("mysql> system tcsh") would work as well.
It's actually possible to execute shell commands on the server that mysqld is running though a client connection (rather than executing commands on the client machine locally) by using MySQL Proxy (scroll down to the "Shell commands from MySQL client" section ).
I'm running version 5.0.95-log on Linux. Prefacing the command either by "system" or by "!" works for the "pwd" and the "ls -l" commands. If I try to change directory using, e.g.
mysql> system cd /home/mydir
the command seems to be accepted. But this apparently does nothing, as following "pwd" and "ls -l" commands indicate that I am still in the same directory. So it appears that there is a stub of limited functionality built in for this, but that we do not actually have full access to the system shell.
In a linux machine you should be able to use the following example
! clear - to clear the screen
! ls - to list files in the current working directory
Basically you should be able to run any command or script using that syntax
NB: Add a back slash before !
