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:

ParameterTypeDescription

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.

Deleting a database connection

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