    Data source settings

    Settings pane of a data source includes the following tabs: General, Options, SSH/SSL, Schemas, Advanced.

    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 that is selected in the Connection type list.

    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 username 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.

    • When using any other of the options (the options are DBMS-specific), PhpStorm 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

    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 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 PhpStorm run. If you exit PhpStorm and open it again, you must 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 Disconnect icon (the
                    Disconnect icon) or Ctrl+F2.

    • Forever: password is saved in the PhpStorm storage. You do not need to provide the password next time you open PhpStorm.

    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 PhpStorm 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.

    Test Connection

    Verifies that the database connection settings are correct and PhpStorm can communicate with the database. To copy the communication information, click the Copy to Clipboard icon the Copy to Clipboard icon.

    Options

    The Options tab includes settings of the database connection.

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

    Item

    Description

    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 PhpStorm uses to switch schemas.

    • Automatic: switch schemas automatically or manually. When this option is enabled, previously-configured search path / current schema are restored automatically between IDE restarts.

    • Manual: switch schemas manually only.

    • Disable: do not switch schemas.

    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, read Query console.

    Run keep-alive query each N seconds

    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 N seconds

    Disconnect from the database after the specified number of seconds.

    Enable DBMSOUTPUT

    (Oracle, IBM Db2 LUW) Enable DBMS_OUTPUT by default for new sessions.

    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, PhpStorm 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.

    Startup script

    Run an SQL query each time you establish a connection.

    Note: if the Single session mode checkbox is cleared, each new query console creates a new connection.

    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.

    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).

    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.

    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, PhpStorm displays you a version that is 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, PhpStorm 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.

    Track databases/schemas creation and deletion

    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, see Pre-introspected objects from system catalogs.

    Virtual objects and attributes

    Defines a path to external-data.xml that stores relations of virtual foreign keys. These relations are used in the auto-completion list, data navigation, and diagrams. For more information about Virtual objects and attributes, see a procedure about creation of virtual foreign keys.

    Code style

    Select a code style that you want to use for schemas. For more information about code style customization, read Code styles for SQL.

    Before connection

    Select tasks that PhpStorm will perform before the first connection (at the start of a process in which the JDBC driver works). Tasks are run sequentially.

    Before connection tasks

    Expert options

    Introspect using JDBC metadata

    Switch to the JDBC-based introspector. Available for all the databases.

    To retrieve information about database objects (DB metadata), PhpStorm 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 intorspector 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 PhpStorm.

    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.

    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.

    Fetch LONG values

    Select how to download values from LONG columns that belong to views of the Oracle catalog. The option is available only for Oracle.

    The default option is XML as it has a better performance. In case of errors in the Oracle XML text generator, consider using the conventional way. Note that the conventional way might increase the introspection time, especially when the ping to the server is long.

    Introspect server objects

    Run introspection for server objects. The option is available only for Oracle.

    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.

    Register REGEXP function

    Register the REGEXP function implementation. This implementation is not available in SQLite by default. The option is available only for SQLite.

    Use SHOW CREATE for source code

    Use the SHOW CREATE statement to generate the CREATE statement for object source code. Source code for triggers and routines is broken in information_schema of MySQL (see Bug #66414 at bugs.mysql.com). The option is available only for MySQL.

    Automatically assign sessionid

    Generate a unique session_id for each connection. With session_id, you can use different session statements (for example, USE). The option is available only for ClickHouse.

    SSH/SSL

    The SSH/SSL tab includes settings for the SSH or SSL connection.

    SSH

    Define a pattern to select the necessary databases and schemas. To get the info about the syntax to be used, position the caret into the field and press Ctrl+Q.

    • @: the current database or schema.

    • *: every database or schema. You can list schemas after *:.

    Consider the following examples:

    • *:*: all schemas in all databases.

    • @:*: all schemas from the current database

    • @:@: only the current schema

    • *:dbo|@:@|db1:s1,s2,s3: the dbo schema from all databases, the current schema, schemas s1,s2,s3 from the db1 database.

    Object filter

    Limit the set of tables and other database objects that are shown in the Database tool window for each data source. For example, if you limit the resolve scope to table:actor.*, then only the actor table will be accessible in the Database tool window (View | Tool Windows | Database).

    Limit the resolve scope to the actor table

    All other tables will be out of the scope. PhpStorm does not resolve objects that are not displayed in the Database tool window.

    Object is not resolved

    Use the following pattern when you compose an expression for the Object filter field.

    <type>:[-]<pattern>, where:

    <type> might be an aggregate, collation, event, fdw, ftable, mview, operator, package, role, routine, sequence, synonym, table, user, view, vtable.

    <pattern> is a regular expression. To exclude an item, prepend with - (minus). For more information about regular expressions, see Class Patterns at JavaTM 2 Platform Standard Edition 5.0 API Specification.

    Show internal system schemas

    Show or hide internal system schemas (for example, pg_toast or pg_temp). The option is available for PostgreSQL only.

    Show template databases

    Show or hide template databases (for example, template1, template0). The option is available for PostgreSQL only.

    Advanced

    The Advanced tab includes the database connection properties, options and environment variables for the JVM database driver.

    The table on the Advanced tab displays a set of connection options that are passed to the database driver as key and value pairs.

    When you select a cell in the Name column, the description of the corresponding option is shown underneath the table.

    To add a row, start editing the values in the last row, where <user defined> and <value> are shown. A new row is added to the table automatically.
