This article covers how to install and use the MyCLI tool on your Ubuntu Linux system. In fact, MyCLI is an easy-to-use command line interface (CLI) for MySQL, MariaDB, and Percona, that helps you speed up development with auto-completion and syntax highlighting features.


How to install the MyCLI tool on your Linux system ?

MyCLI tool is based on Python and needs to be installed via pip. Make sure PIP and python development libraries are installed.:

$ yum install python-pip
$ yum -y install python-devel

MyCLI Features include:

  • Auto-completion as you type for SQL keywords as well as tables, views and columns in the database. Auto-completion is on by default. The REPL will pop up a suggestion menu as soon as you start typing. The suggestions are context sensitive based on the position of the cursor. eg: Only tables are suggested after the FROM keyword, only column names are suggested after the WHERE clause.
  • Syntax highlighting using Pygments. Syntax highlighting has plenty of themes that can be changed via the config file.
  • Smart-completion (enabled by default) will suggest context-sensitive completion.
  • SELECT * FROM <tab> will only show table names.
  • SELECT * FROM users WHERE <tab> will only show column names.
  • Support for multiline queries.
  • Favorite queries with optional positional parameters. Favorite Queries are a way to save frequently used queries with a short name. Save a query using \fs alias query and execute it with \f alias whenever you need.
  • Timing of sql statments and table rendering.
  • Config file is automatically created at ~/.myclirc at first launch.
  • Log every query and its results to a file (disabled by default).
  • Pretty prints tabular data (with colors).
  • Support for SSL connections.
  • There are two types of keybindings available. Emacs mode and Vi mode
  • Cross-platform support – runs under Linux and macOS. The software may run under Windows but this is not tested.

Executing queries from the MySQL Command Line

This article will guide you on how to run queries from the 3MySQL command line. The MySQL #Command Line Tool is a useful way to run #queries from the command line. It’s easy to run select queries and display the results in either a horizontal or vertical format, and the queries run are kept in a history file which you can navigate through. 

If you don't want to run a particular query after all you can use the c command to clear it.

The most common way to get a list of the MySQL #databases is by using the mysql client to connect to the MySQL server and run the SHOW DATABASES command. If you haven't set a password for your MySQL user you can omit the -p switch.

To Connect to a MySQL Database:

1. Click Services tab.

2. Expand the Drivers node from the Database Explorer.

3. Enter User Name and Password.

4. Click OK to accept the credentials.

5. Click OK to accept the default schema.

6. Right-click the MySQL Database #URL in the Services window.
