Как показать список всех баз данных в MySQL

При администрировании серверов баз данных MySQL одна из наиболее распространенных задач, которые вам нужно будет выполнить, — это познакомиться со средой. Сюда входят такие задачи, как перечисление баз данных, находящихся на сервере, отображение таблиц конкретной базы данных или получение информации об учетных записях пользователей и их привилегиях.

В этом руководстве объясняется, как отобразить все базы данных на сервере MySQL или MariaDB через командную строку.

Показать базы данных MySQL

Самый распространенный способ получить список баз данных MySQL — это использовать клиент mysql для подключения к серверу MySQL и выполнить команду SHOW DATABASES .

Получите доступ к серверу MySQL с помощью следующей команды и при появлении запроса введите пароль пользователя MySQL:

Из оболочки MySQL выполните следующую команду:

Команда напечатает список всех баз данных, для которых пользователю предоставлены какие-либо права . Результат будет примерно таким:

Еще одна команда, которую вы можете использовать для SHOW SCHEMAS списка баз данных, — это SHOW SCHEMAS которая является синонимом команды SHOW DATABASES :

Вывод будет таким же, как при использовании команды SHOW DATABASES :

Показать все базы данных MySQL

Чтобы вывести список всех баз данных на сервере MySQL, вам необходимо войти в систему как пользователь, имеющий доступ ко всем базам данных, по умолчанию это пользователь root MySQL или установить глобальную привилегию SHOW DATABASES .

Войдите в систему как root-пользователь MySQL:

Запустите команду SHOW DATABASES :

Вы увидите список всех баз данных на сервере MySQL:

Фильтрация результата

Предложение LIKE можно использовать для фильтрации вывода команды SHOW DATABASES соответствии с определенным шаблоном.

Например, следующий оператор вернет все базы данных, имена которых начинаются с ‘open’:

Если вы хотите выполнить более сложный поиск, вы запрашиваете таблицу schemata из базы данных information_schema которая содержит информацию обо всех базах данных.

Следующая инструкция предоставит вам список всех баз данных, которые начинаются с «open» или «word»:

Показать базы данных MySQL из командной строки

Чтобы получить список баз данных без входа в оболочку MySQL, вы можете использовать либо команду mysql с параметром -e что означает выполнение, либо mysqlshow который отображает информацию о базах данных и таблицах.

Это особенно полезно, когда вы хотите работать со своими базами данных MySQL с помощью сценариев оболочки.

Выполните следующую команду на своем терминале, чтобы отобразить список всех баз данных:

Вот пример использования команды mysqlshow :

Вывод будет идентичен выводу предыдущей команды.

Если вы хотите отфильтровать вывод, вы можете использовать команду grep .

Выводы

Вы узнали, как получить список всех баз данных на вашем сервере MySQL.

How to list all databases in MySQL

You will show you how to list all databases in MySQL. MySQL is an open-source relational database management system commonly used with web applications such as WordPress, Magento, etc. E. In this tutorial, we will show you how to list all databases in MySQL on Linux VPS .
Before you start listing all tables in MySQL, make sure that you have full access to your Linux server, or at least you have a system user with sudo privileges that you can use to connect to your server. After connecting to the server via SSH, run the following command to check if the MySQL database server is installed on your VPS and what the version is:

The result of the command should be similar to the output:

# mysql -V
mysql Ver 14.14 Distrib 5.7.22, for Linux (x86_64) using EditLine wrapper

Then, to connect to the MySQL database server through the command line as the root user, execute the following command:

MySQL will ask you to enter a password for the user root. Enter the password and press Enter. If you have not yet set a password for user root, you can use the following command:

Of course, it is always recommended to keep your services secure, so if you haven’t already set a password for root in MySQL, you can do it now using the mysql_secure_installation command without arguments:

Then answer the security questions as follows:

Would you like to setup the VALIDATE PASSWORD plugin?
Press y|Y for Yes, any other key for No: y

Please set the password for root here.
New password:

Do you wish to continue with the password provided? (Press y|Y for Yes, any other key for No) : y

Remove anonymous users? (Press y|Y for Yes, any other key for No) : y

Disallow root login remotely? (Press y|Y for Yes, any other key for No) : y

Remove test database and access to it? (Press y|Y for Yes, any other key for No) : y

Reload privilege tables now? (Press y|Y for Yes, any other key for No) : y

Then connect to the MySQL database server with the user root and enter the new password root.

gud site for learn

you can use the -e option to execute some queries on the command line, EG, to list databases:
mysql -e “show databases” -u -p

Nice tips, very helpful.

how can i know if there is a database server on my pc?
i tried this command:
-e “show databases” -u -p
and i got this error:
ERROR 2006 (HYOOO):MySQL server has gone away
No connection. Trying to reconnect. . .
Connection id: 19
Current database: TCPDUMP

ERROR 1064 (42000): You have and error in your SQL syntax;check the manual to your corresponds to your MySQL server version for the right syntax to use near ‘-e “show databases” -u -p’ at line 1

can anyone help me?

In this above error indicates Mysql error state.so ,u can check to identify correcly connections are established or not,and once u check your transcational data.

I suppose you are using …. Linux? or Windows? if you are using Windows, just go to your control panel and check in “Add/Remove Programs” if you see something like “mysql”. Also you can check in services under Administrative tools.
Now, if you are in Linux,
type “mysql” and then press “TAB” twice and you will see a list of commands like:

mysql mysqlimport
mysqlaccess mysql_install_db
mysqladmin mysqlmanager
…

then mysql is installed. To know if it is running:

and you will see a “3306/tcp open mysql”.

Also, if you copy+paste some codes or example from web pages remember that sometimes the quotation mark is changed (looks similar but they are not)

I hope this is helpful

Very helpful tips, thanks

While migrating a database from an old server (Ubuntu 10.04) to a new one (14.04) I am getting this error: ERROR 2006 (HY000) at line 2692: MySQL server has gone away

All the other databases worked except for this one. It will run for about 10 minutes then fail. Here is the command I used: mysql -u root -p cascade_test Matthew Oct 23, 2014 @ 20:12

Fixed! It wasn’t working and I was using PuTTY. I tried it on my mac through terminal and it worked! Strange…

Sorry to be negative, your end comment:

“Since you are new to MySQL, it is better to use GUI tools”

I have to disagree with, it is far better and quicker to learn to use the shell commands to do server admin, especially if doing many actions, like creating many databases or importing large amounts of data.

But phpmyadmin is a great tool if you are working in the gui enviroment and want to make an adjustment for one off changes.I have not tried your other suggestion, but will now

And as a positive I would like to say a big thanks to all the help I have got from your pages. On a search to resolve a problem I will always click the cyberciti link first.

Thanks bro 🙂 it was really useful!

1. Consider the following relations of medical consultation centre:
FACULTY (F_id, F-name, F-designation).
PATIENT (P_id, P_name, p_address, date_of_ registration).
CONSULTATION DATE (C_date, F_id, P_id).
Create tables for above relations considering suitable data types and constraints. Insert 5
appropriate tuples in the tables.
Write the SQL statements for the following queries.
1. Generate list of patients and their consultation detail.
2. Find patients consulted by specific faculty.
3. Find the details of the entire faculty whose designation is a senior doctor and have
consultation date next month.
4. Find the patient whose consultation date is today along with the concerned faculty
detail.
