Query consoles

Last modified: 11 October 2024

Enable the Database Tools and SQL plugin

This functionality relies on the Database Tools and SQL plugin, which is bundled and enabled in IntelliJ IDEA by default. If the relevant features are not available, make sure that you did not disable the plugin.

note

The Database Tools and SQL plugin is not available in IntelliJ IDEA Community Edition.

  1. Press CtrlAlt0S to open 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.

Overview

Query or database consoles are SQL files that are attached to a data source. You can write and execute SQL statements in query consoles the same way as you do it in terminal. The consoles are not included in the project context.

When you create a data source, the data source's default query console is created automatically. If necessary, you can create additional query consoles.

Query console

Each console creates a new connection session. If you do not want to create new connections, enable single session mode.

All the created query consoles are located in the internal Database Consoles directory. To open this folder, open the Project tool window (Alt01) and navigate to Scratches and Consoles | Database Consoles. On your machine, the query console files are stored in the consoles subdirectory of the IDE configuration directory.

For more information about working with query results in query consoles, refer to Query results.

Database connection session

For each console, a database connection session is created automatically. You can create new connection sessions and attach your console to existing ones in the console toolbar.

In the following example, the PostgreSQL console is associated with the guest.public schema of a data source and connected to it via the console connection session. You can change the console session to actor or create a new session and attach the console to it.

Change the connection session

Code editor

The code editor is where you compose your SQL statements using the resolve modes and coding assistance features, and execute them against the associated data source.

Find the code editor toolbar controls in Code editor controls. Read more about the editor in Editor basics.

SQL statement execution

When you execute a statement, the Services tool window opens. The Services tool window displays available connection sessions, Output and Result tabs. For more information about the Services tool windows, refer to Services tool window.

  • If the executed statement retrieves data (for example, SELECT), results are displayed in the Result tab that has a title of a qualified table name. For more information about creating custom titles for result tabs, refer to Use custom titles for tabs with results.

  • If the executed statement does not retrieve data, results are displayed in the Output tab.

Work with console files

Create a query console

To create a console, use one of the following actions in the Database tool window ( View | Tool Windows | Database).

  • Click a data source and select File | New | Query Console.

  • Right-click a data source and select New | Query Console.

  • Click a data source, press AltInsert, and select Query Console.

  • Click a data source, press CtrlShiftF10, and select New Query Console.

  • Click a data source and press CtrlShift0Q.

note

New console means a new connection to a data source. You can work with just one connection for the data source and have all consoles use that same one connection. Read more about the single session mode in Single session mode.

Open a console

When a console is open, you can write SQL here, run it and get the result.

  • In the Project tool window ( View | Tool Windows | Project) , navigate to Scratches and Consoles | Database Consoles | <data_source_name>, double-click a console file.

Select the isolation level for database transactions and the way the transactions are committed.

  • Auto: the current transaction is committed automatically when you submit your local changes to the database server.

  • Manual: the changes submitted to the database server are accumulated in a transaction that can either be committed or rolled back explicitly by means of the Submit and Commit (the Submit and Commit icon) or Roll Back (the Roll Back button) buttons on the toolbar.

For more information about database transaction modes and isolation, refer to Submit changes to a database.

Playground

File Resolve Mode

Select the resolve mode to manage the context that database objects in your code are resolved to.

  • Playground: default mode for query consoles. All the database objects are resolved to the same context.

  • Script: default mode for local SQL files. The USE SQL statement (SET search_path TO for PostgreSQL) overrides the default context that the database objects are resolved to.

For more information about the resolve modes, refer to Resolve modes.

In the following video, the public schema is selected as default for the query console. The schema contains the actor table, whereas the information_schema schema does not contain it. When the resolve mode is Playground, the database object is resolved to default schema in both SELECT statements, because all the statements are considered unrelated.

Once the resolve mode is changed to Script, the second SELECT statement is considered related to the SET search_path TO information_schema one. The actor table is no longer resolved in that statement.

In-Editor Results

Toggle the display of query result within the code editor of query console.

For more information about the in-editor results, refer to In-Editor Results.
