General

The General tab includes settings that you need to specify for a database connection.

The set of fields and controls on the tab depends on the option selected in the Connection type list.

Data Source and Drivers dialog: General tab of Data Sources settings

Item	Description
Connection type	A connection type that you want to use for the database connection. URL only This option, generally, is for editing the database connection URL directly. When you select this option, only the following fields are available: User, Password, and URL. You should edit the URL right in the field. Your user name and password, if necessary, are specified in the corresponding fields or within the URL in the format appropriate for the JDBC driver that you are using. For the URL only connection type, the JDBC URL is stored in plain text as is, and is also available in IDE log file and data source information. Other connection types When using any other of the options (the options are DBMS-specific), IntelliJ IDEA forms the database connection URL automatically using the info in the fields above the URL field. In all such cases, normally, you don't need to edit the URL (though you can if you want).
Driver	Specify the driver from the Drivers list that you want to use for the connection.
File	The path to the database file. Use the Open icon () to select an existing database file. The Save icon () creates a copy of a database file and changes a path to the copy location.
Path	The path to the database file or folder. Use the Open icon () to select an existing database file or a folder.
Host	The hostname (domain name) or the IP address (IPv4 or IPv6) of the computer where the database is located. If the database is on your local computer, specify localhost or 127.0.0.1. If you are using SSH, the database host must be accessible by the specified domain name or IP address from the computer on which the SSH proxy runs. See SSH/SSL tab.
Port	The database port number.
Database	The name of the target database or schema.
User	The name of your database user account.
Password	The password for the database user.
Save	Save settings for the password field. You can select the following options for storing your password: Never: password is prompted each time you establish a connection with a database. Until restart: password is saved only for the current IntelliJ IDEA run. If you exit IntelliJ IDEA and open it again, you have to provide the password again. For session: password is saved only for the current connection session with a database (until you disconnect from it). You can terminate the connection by pressing the Deactivate icon () or `Ctrl+F2`. Forever: password is saved in the IntelliJ IDEA storage. You do not need to provide the password next time you open IntelliJ IDEA. IDE Passwords Settings: click to access the IDE password storage settings. You can also access them by opening the Appearance & Behavior \| System Settings \| Passwords settings page `Ctrl+Alt+S`. For more information about the IDE passwords settings, refer to Passwords topic.
Create database	Adds an argument to the URL to create a database. This option is available only in some database management systems (for example, in the Apache Derby (Embedded)).
URL	The URL that IntelliJ IDEA will use to connect to the database. The user interface for specifying the URL is different depending on which option is selected in the Connection type list. For the URL only connection type, the URL field contents are stored in plain text, and are also available in the IDE log file. Use the designated fields to provide your sensitive connection details instead of putting them into the URL field.
Test Connection	Verifies that the database connection settings are correct and IntelliJ IDEA can communicate with the database. To copy the communication information, click the Copy.

Options

The Options tab includes settings of the database connection.

The set of fields and controls on the tab depends on the option selected in the Connection type list.

Data Source and Drivers dialog: Options tab of Data Sources settings

Item	Description
Connection
Read-only	Set the read-only status. Select the checkbox to protect the data source from accidental data modifications. If the checkbox is selected, you cannot modify the data in the Data editor. Data modifications might be possible in the query console if the driver does not support the read-only status.
Transaction control	Set the isolation level for database transactions and the mode of how the transactions are committed. Auto: the current transaction is committed automatically when you submit your local changes to the database server. Manual: changes submitted to the database server are accumulated in a transaction that can either be committed or rolled back.
Switch schema	Define a mode that IntelliJ IDEA uses to switch schemas. Automatic: switch schemas automatically or manually. When this option is enabled, the previously configured search path or the current schema are restored automatically between IDE restarts. Manual: switch schemas manually only. Disable: do not switch schemas.
Time zone	Select a time zone to use with the data source. For example, select the time zone of the host that your data source is connected to.
Single session mode	Enable the single session mode. Single session mode means that the data source and all consoles use one and the same session. This mode allows you to see the temporary objects in the database tree, or use the same transaction in different consoles. For more information about consoles, refer to Query consoles.
Run keep-alive query each	Run a keep-alive query to keep the connection alive. You can define the custom query in the driver settings for unsupported databases.
Auto-disconnect after	Disconnect from the database after the specified number of seconds.
Single database mode	In the database tree view, show and enable only the database that you specified in the connection settings. When you connect to a data source, IntelliJ IDEA can retrieve and display you all the databases that the data source has. But in some cases (for example, with certain settings of PgBouncer), you can or are allowed to work only with a certain database. In the database tree view with the Single database mode enabled, you see only the database that you specified in the connection settings. Consider using this setting for PostgreSQL, Azure SQL Database, Greenplum, Amazon Redshift.
Enable DBMSOUTPUT	(Oracle, IBM Db2 LUW) Enable DBMS_OUTPUT by default for new sessions.
Startup script	Run an SQL query each time you establish a connection. To use built-in IDE macros in your startup script, click Insert Macros. Note: if the Single session mode checkbox is cleared, each new query console creates a new connection.
Introspection
Auto sync	Synchronize the actual state of the database automatically. The state of the database means the database tree view that you see in the Database tool window. If the Auto sync checkbox is selected, the view of the data source is automatically updated: When you click OK in the Data Sources and Drivers dialog. When you run DDL SQL statements in the database consoles associated with the data source. Starting from version 2024.2, for Oracle and Microsoft SQL Server, IntelliJ IDEA analyzes which objects could be potentially modified by the query and only refreshes the set of these objects. If the statement indirectly modifies any other objects, the IDE can miss such modifications. In this case, click Refresh on the toolbar of the Project tool window to perform a complete model refresh. If the Auto sync checkbox is cleared, the view of the data source in the Database tool window is synchronized with the actual state of the database only when you click the Refresh button or press `Ctrl+F5`) in the toolbar.
Load sources for	Load source code of views, procedures, packages and other database objects for the selected category of schemas: all schemas (All schemas), all schemas excluding system schemas (All excl. system schemas), or disable the feature (None). To change this setting for several data sources simultaneously, select the corresponding data sources. Right-click the selection and navigate to Load Sources and select an option.
Default level	(Oracle) Default introspection level for the database objects.
Use session template	Select a template to be used for your sessions.
Warn when editing outdated DDL	Display a notification if the cached DDL differs from the actual DDL in the database. Every time you open source code, IntelliJ IDEA displays you a version loaded during the indexing process. But if someone changes the source code from another workstation, the indexed version becomes outdated. If your version is older than the one in the database, you see the following notification: `Cached object differs from the object in the database`.
Track databases/schemas creation and deletion	When you create, delete, or rename a schema, IntelliJ IDEA updates the list of available schemas in the introspection scope window. To see the introspection scope, click the button near the data source name in the Database tool window.
Use pre-introspected objects for system catalogs that are not introspected	Toggles the usage of pre-introspected objects for system catalogs. For more information about introspection and system catalogs, refer to Pre-introspected objects from system catalogs.
Automatic introspection interval N minutes	Run introspection for the data source once in the specified number of minutes.
Virtual objects and attributes	Defines a path to external-data.xml that stores relations of virtual foreign keys, expressions of virtual columns, and statements of virtual views. For more information about virtual database objects, refer to Virtual objects section topics.
Other
Code style	Select a code style that you want to use for schemas. For more information about code style customization, refer to Code styles for SQL.
Before connection	Select tasks that IntelliJ IDEA will perform before the first connection (at the start of a process in which the JDBC driver works). Tasks are run sequentially.
Session Templates	Create templates for your sessions. Template settings override general connection settings of a data source. In a template, you can set the following options: Authentication, Read-only, Startup script, Driver.

Expert options

Item	Description
Disable incremental introspection	Do not perform the incremental introspection. The option is available for Oracle, Microsoft SQL Server, PostgreSQL and similar databases, . With the incremental introspection, the introspector detects objects changed in the database after the previous introspection and loads only these objects. When you enable this option, the introspector always loads all objects. It might greatly increase the introspection time.
Do not use xmin in queries to pgdatabase	Do not use the `xmin` attribute in queries to the `pg_database` table. Use this workaround when `xmin` is absent in `pg_database`. Note that your database might be corrupted. The option is available only for PostgreSQL.
Introspect using JDBC metadata	Switch to the JDBC-based introspector. Available for all the databases. To retrieve information about database objects (DB metadata), IntelliJ IDEA uses the following introspectors: A native introspector (might be unavailable for certain DBMS). The native introspector uses DBMS-specific tables and views as a source of metadata. It can retrieve DBMS-specific details and produce a more precise picture of database objects. A JDBC-based introspector (available for all the DBMS). The JDBC-based introspector uses the metadata provided by the JDBC driver. It can retrieve only standard information about database objects and their properties. Consider using the JDBC-based introspector when the native introspector fails or is not available. The native introspector can fail when your database server version is older than the minimum version supported by IntelliJ IDEA. You can try to switch to the JDBC-based introspector to fix problems with retrieving the database structure information from your database. For example, when the schemas that exist in your database or database objects below the schema level are not shown in the Database tool window.
Isolate class path	Isolate class path used by JDBC driver.
Use IDE proxy settings	Passes IDE proxy settings to JDBC process.
