![]() ![]() Many years after SQLite was widely deployed, we have resistedįixing the problem for fear of breaking legacy applications.Īt this time SQLite supports only FOR EACH ROW triggers, not FOR EACH Statement if any of the names in the "UPDATE OF" clause are notĬolumns in the table. It would be more helpful if SQLite would fail the CREATE TRIGGER ![]() Unrecognized column names are silently ignored. One of the terms in the SET clause of the UPDATE statement.ĭue to an historical oversight, columns named in the "UPDATE OF"Ĭlause do not actually have to exist in the table being updated. Syntax is used, then the trigger will only fire ifĬolumn-name appears on the left-hand side of The trigger fires once for each row that is deleted, inserted, The following operations: DELETE, INSERT, UPDATE. That are automatically performed when a specified database eventĮach trigger must specify that it will fire for one of The CREATE TRIGGER statement is used to add triggers to theĭatabase schema. table-name AS table-alias INDEXED BY index-name NOT INDEXED table-function-name ( expr ), AS table-alias ( select-stmt ) ( table-or-subquery ), join-clause 2. To view and edit data of a database object, open Data editor and viewer by double-clicking the object.Schema-name. To write and run queries, open the default query console by clicking the data source and pressing F4. Aqua will introspect and show them.įor more information about working with database objects in Aqua, refer to Database objects. To see more schemas under your new data source node, click the N of M button and select the ones you need. įor more information about the Database tool window, see the corresponding reference topic. If you also want to work with other schemas, in the Schemas tab, select them for the introspection.įind your new data source in the Database tool window ( Alt+1). (Optional) By default, only the default schema is introspected and available to work with. In case of any connection issues, refer to the Cannot connect to a database page. To do that, click the Test Connection link at the bottom of the connection details area. If you need to use a JDBC URL with certain additional settings, paste it in the URL field.įor the reference information about connection settings (for example, Host, Port, and so on) on the General and other tabs of Data Sources and Drivers dialog ( Command I), see Data source settings.Įnsure that the connection to the database can be established using the provided details. ![]() In the URL field, Aqua generates the JDBC URL automatically using the values of other connection settings. Alternatively, paste the JDBC URL in the URL field. If there is no Download missing driver files link, then you already have the required drivers. For more information about connecting to a database with your driver, refer to Add a user driver to an existing connection. You can also use your drivers for the database instead of the provided ones. Location for the downloaded JDBC drivers is the Aqua configuration directory. For a direct download link, refer to the JetBrains JDBC drivers page. Click this link to download drivers that are required to interact with a database. You can either specify them separately and use the automatically generated URL, or you can enter the URL directly in the corresponding field.Ĭheck if there is a Download missing driver files link at the bottom of the connection settings area. In the Driver list, leave the default driver option, unless another driver is required for your connection.įrom the Connection type list, select the connection type depending on the connection details that you have:ĭefault: connect by using the path to SQLite database file.įor the URL only connection type, the JDBC URL that you enter is used as is.įor the other connection types, the JDBC URL is broken down into connection details. ![]() In the General tab of Data Sources and Drivers dialog right pane, specify the driver and connection type. Navigate to Data Source and select SQLite. In the Database tool window ( View | Tool Windows | Database), click the New icon ( ) in the toolbar. You can do this using one of the following ways:įrom the main menu, navigate to File | New | Data Source and select SQLite. To connect to the database, create a data source that will store your connection details. For example, if you want to run a database on your machine and connect to that database, the corresponding DBMS software must be installed on the machine first. It is assumed that you already have the necessary prerequisites and the database is up and running. This topic presents a general procedure on how you can create a data source for the connection to your SQLite database in Aqua, and run a test connection. To download SQLite database software, refer to the official software downloads. For full information about SQLite, refer to the official documentation. ![]()
