    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.

    • Other connection types

      When using any other of the options (the options are DBMS-specific), WebStorm 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 (The Open icon) to select an existing database file.

    The Save icon (the Save button) 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 (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.

    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 WebStorm 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, WebStorm 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, WebStorm analyzes which objects could be potentially modified by the query and only refreshes the set of these objects.

    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 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, WebStorm 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, WebStorm 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.

    Introspection scope window

    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), WebStorm 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 WebStorm.

    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.

    Kubernetes

    With WebStorm, you can connect to a database running in a Kubernetes cluster.

    The Kubernetes tab is not available for embedded databases (for example, SQLite, Apache Derby, or HSQLDB) that don't have dedicated ports.
