Как посмотреть базу данных в pycharm

Не правильно открывается SQLite БД в PyCharm

Создавался файл ‘name.db’ иконка у него была базы данных и при открытии делался коннект с ним и можно было посмотреть что в нем есть(таблицы, колонки). Теперь создается файл ‘name.db’на иконке написано sql и открывается как простой файл без ничего Пробовал: удалять и создавать по новой, менять в настройках диалект(вероятно что-то там не то сделал) И такая проблема только в одном проекте, в других все нормально. Как в этом вернуть исходное состояние открытия DB

Database Tools and SQL

This functionality relies on the Database Tools and SQL plugin, which is bundled and enabled in PyCharm by default. If the relevant features aren’t available, make sure that you didn’t disable the plugin.

The Database Tools and SQL plugin is available only in PyCharm Professional.

1. Press Control+Alt+S to open the IDE settings and then select Plugins .
2. Open the Installed tab, find the Database Tools and SQL plugin, and select the checkbox next to the plugin name.

This section provides an overview of basic functionality that is available with the Database Tools and SQL plugin in PyCharm. For more information about database features, refer to the official DataGrip documentation.

The database management functionality in PyCharm is supported by the Database Tools and SQL plugin. The plugin provides support for all the features that are available in DataGrip, the standalone database management environment for developers. With the plugin, you can query, create and manage databases. Databases can work locally, on a server, or in the cloud. The plugin supports MySQL, PostgreSQL, Microsoft SQL Server, SQLite, MariaDB, Oracle, Apache Cassandra, and others. See the full list of supported vendors in Create a data source.

Official documentation and software

• For full information about SQLite, refer to the official documentation.
• To download SQLite database software, refer to the official software downloads.

This topic presents a general procedure on how you can create a data source for the connection to your SQLite database in PyCharm, and run a test connection. It is assumed that you already have the necessary prerequisites and the database is up and running. For example, if you want to run a database on your machine and connect to that database, the corresponding DBMS software must be installed on the machine first.

Connect to an SQLite database

1. To connect to the database, create a data source that will store your connection details. You can do this using one of the following ways:
   • In the main menu, go to File | New | Data Source and select SQLite .
   • In the Database tool window ( View | Tool Windows | Database ) , click the New icon () in the toolbar. Navigate to Data Source and select SQLite .
2. In the General tab of Data Sources and Drivers dialog right pane, specify the driver and connection type.
   1. In the Driver list, leave the default driver option, unless another driver is required for your connection.
   2. From the Connection type list, select the connection type depending on the connection details that you have:
      • default : connect by using the path to SQLite database file.
      • URL only : connect by using only the URL .

   For the URL only connection type, the JDBC URL that you enter is used as is.

   For the other connection types, the JDBC URL is broken down into connection details. You can either specify them separately and use the automatically generated URL, or you can enter the URL directly in the corresponding field.

Check if there is a Download missing driver files link at the bottom of the connection settings area. Click this link to download drivers that are required to interact with a database. For a direct download link, refer to the JetBrains JDBC drivers page. Location for the downloaded JDBC drivers is the PyCharm configuration directory. You can also use your drivers for the database instead of the provided ones. For more information about connecting to a database with your driver, refer to Add a user driver to an existing connection. If there is no Download missing driver files link, then you already have the required drivers.

Specify the database connection details. Alternatively, paste the JDBC URL in the URL field.

• To connect to an existing SQLite database, specify a file path to the database file in the File field. Alternatively, click the Open button () and navigate to the file.
• To create a new SQLite database, change the default identifier.sqlite name of the database, if needed. Alternatively, click the New button () and specify the name and location for your new database file.
• Also, to create a database, you can drag an SQLite database file to the Database tool window.
• In the URL field, PyCharm generates the JDBC URL automatically using the values of other connection settings. If you need to use a JDBC URL with certain additional settings, paste it in the URL field. The general URL to use is as follows:
  • Format: jdbc:sqlite:/
  • Example: jdbc:sqlite:/Users/JetBrains/db/myDatabase

• Paste the JDBC URL in the URL field.
• In the URL field, PyCharm generates the JDBC URL automatically using the values of other connection settings. If you need to use a JDBC URL with certain additional settings, paste it in the URL field. The general URL to use is as follows:
  • Format: jdbc:sqlite::memory:
  • Example: jdbc:sqlite::memory:

• Paste the JDBC URL in the URL field.
• In the URL field, PyCharm generates the JDBC URL automatically using the values of other connection settings. If you need to use a JDBC URL with certain additional settings, paste it in the URL field.

For the reference information about connection settings (for example, Host , Port , and so on) on the General and other tabs of Data Sources and Drivers dialog ( Shift+Enter ), see Data source settings.

Ensure that the connection to the database can be established using the provided details. To do that, click the Test Connection link at the bottom of the connection details area. In case of any connection issues, refer to the Cannot connect to a database page.

(Optional) By default, only the default schema is introspected and available to work with. If you also want to work with other schemas, in the Schemas tab, select them for the introspection.

Click OK to create the data source.

Find your new data source in the Database tool window ( Shortcut is missing ) .

• For more information about the Database tool window, see the corresponding reference topic. To see more schemas under your new data source node, click the N of M button and select the ones you need. PyCharm will introspect and show them.
• For more information about working with database objects in PyCharm, refer to Database objects.
• To write and run queries, open the default query console by clicking the data source and pressing F4 .
• To view and edit data of a database object, open Data editor and viewer by double-clicking the object.

Pycharm – инструменты для баз данных

PyCharm поддерживает поддержку интерфейса с различными типами баз данных. Как только пользователь предоставляет доступ к созданной базе данных, он предоставляет схему схемы базы данных с инструментами написания SQL, которые обеспечивают завершение кода. В этой главе мы сосредоточимся на подключении к базе данных MySQL, что включает следующие шаги.

Добавление источника данных

Важно помнить, что PyCharm поддерживает широкий спектр соединений с базами данных.

Шаг 1

Откройте окно инструмента базы данных View -> Tool Windows -> Database> и откройте диалоговое окно под названием Data Sources and Dialog .

Теперь выберите базу данных MySQL для добавления нового источника данных.

Шаг 2

Пользователь должен загрузить отсутствующие файлы драйвера, чтобы получить правильное соединение с базой данных MySQL .

Шаг 3

Теперь укажите параметры конфигурации для достижения соединения.

Хост – если сервер базы данных находится на другом компьютере, замените localhost на IP-адрес хоста сервера, например, 172.20.240.163.

Порт – Порт сервера MySQL по умолчанию – 3306. Если ваш сервер использует другой порт, укажите этот порт.

Имя пользователя и пароль – это необходимые учетные данные.

Шаг 4

Всегда проверяйте, что соединение с базой данных успешно с помощью функции Test Connection .

Тестирование соединения также включает создание тестовой таблицы посредством запроса и их выполнение. После успешного выполнения вы можете удалить базу данных.
