SQLCreateClass

SQL command: CREATE CLASS

Create Class

The SQL Create Class command creates a new class in the schema. NOTE: If a cluster with the same name exists in the database will be used as default cluster.

Syntax

CREATE CLASS <class> [<super-class>](EXTENDS) [<clusterId>*](CLUSTER)

Where:

• class is the class to create
• super-class, optional, is the super-class to extend
• clusterId can be a list separated by comma (,). At least one element is mandatory and it's also the default cluster id

Examples

Create the class 'Account': CREATE CLASS Account

Create the class 'Car' that extends 'Vehicle': CREATE CLASS Car extends Vehicle

Create the class 'Car' with clusterId 10: CREATE CLASS Car CLUSTER 10

Abstract class

Create the class 'Person' as Concepts#Abstract_Class abstract: CREATE CLASS Person ABSTRACT

To remove a class use the Drop Class command.
