Database tool window

Overview

In the Database tool window (View | Tool Windows | Database), you can work with databases and DDL data sources. You can view and modify data structures in your databases, and perform other associated tasks. To view a table, double-click the table. For more information about different viewing modes, see View data.

the Database Explorer

The available data sources are shown as a tree of data sources, schemas, tables and columns. If no data sources are currently defined, use the New command Alt+Insert to create a data source.

Most of the functions in this window are accessed by means of the toolbar icons or context menu commands. (If the toolbar is not currently shown, click the Settings button on the title bar and select Show Toolbar.) Many of the commands have keyboard shortcuts. If the toolbar is hidden, the Refresh and Open Query Console commands can be access by means of the title bar icons (the Refresh button and the Jump to Query Console button respectively).

SQL Scripts | SQL Generator

Ctrl+Alt+G

Generate data definition structures for database objects. For example, you can generate DDL files for a single table or for all the tables in the schema. Also, you can customize generation settings. For example, you can set what syntax to use for table creation: CREATE TABLE or CREATE TABLE IF NOT EXISTS.

Generate data definition structures

SQL Scripts | Request and Copy Original DDL

Ctrl+Alt+G

If your database stores DDL of the object, retrieve DDL from the database.

SQL Scripts | Generate DDL to Clipboard

Ctrl+Alt+Shift+G

Generate DDL of the object and copy it to the clipboard.

SQL Scripts | Generate DDL to Query Console

Ctrl+Alt+Shift+B

Generate DDL of the object and paste it to a query console.

Database Tools | Modify Comment

Modify or add a comment to a database object like if you have run the following query COMMENT ON SCHEMA information_schema IS 'myComment';.

Database Tools | Truncate…

Remove all the rows in the selected table.

Database Tools | Manage Shown Schemas

Open a popup with available schemas for the current data source.

Popup with available schemas

Database Tools | Hide Schemas

Hide the schema that is selected.

Database Tools | Force Refresh

Ctrl+Shift+F5

Delete the data source information from cache and load it again. This action is available on the data source node only.

Database Tools | Forget Cached Schemas

Delete the information that IntelliJ IDEA has accumulated about your database. This action is available on the data source node only.

Use this command when you experience issues like wrong display of data structures or errors during synchronization.

To check if this has eliminated the problem, use the Synchronize command.

Database Tools | Properties

Shift+Enter

Open the Data Sources and Drivers window where you can customize data source settings.

Database Tools | Drop Primary Key

Remove the primary key constraint for the current table.

Database Tools | Drop Foreign Key

Remove the foreign key constraint.

Diagnostics | Dump Model

Generate an IntelliJ IDEA-specific representation of the database structure (a database model).

Dump model

Diagnostics | Diagnostic Refresh

Reload the metadata from the database and generate a LOG file. This information might be helpful for the support team when you think that your introspection is slow.

Diagnostic refresh

Diagnostics | Prepare Introspector Diagnostics

Generate three files that include information about the data source (dataSource.txt), a module that was used to load the metadata from the database (introspector.txt), and a part of the database model (model.xml).

This information might be helpful when introspection works incorrectly. For example, when you see something outdated or do not see new objects.

Prepare introspector diagnostic

Import Data from File…

Import a text file containing delimiter-separated values (CSV, TSV, and so on) into your database.

If a schema is currently selected, IntelliJ IDEA will create a new table for the data that you are importing. If a table is selected, IntelliJ IDEA will try to add the data to the selected table.

Full-text Search
