Relational Database

Here, you can create one or multiple database connections to already existing relational databases. The supported database types are MySQL, PostgreSQL, SQLite, MariaDB and Microsoft SQL.

See Internal PostgreSQL for a list of available functions after the connection has been established and a deeper explanation of relational databases.

Connecting to the database

With the create function, you can create an instance for each new database you want to connect to. To do so, insert a name in the first field and fill the following information in the second field:

Parameter	Type	Description
dialect	String	The dialect of the database you are connecting to. One of mysql, postgres, sqlite, db2, mariadb and mssql.
database	String	The name of the database.
username	String	The username which is used to authenticate against the database.
password	String	The password for the corresponding user.
host	String	The host of the database. Can be either a URL or an IP address.
port	String	(optional) The port of the database. If not defined, the standard port (5432) is tried.
ssl	String	(default: true) A flag that defines if the connection should encrypted with ssl or not.

After creating the instance, use the function isConnected to test the database connection.

After successfully creating a connection to a database, you can use all the functions listed in internal PostgreSQL.

Simply drag the delete function onto the board and insert the name of the instance, whose connection you want to delete.
