SQL Class Reference

These topics provide reference information for Snowflake classes. A class is an extensible object type that encapsulates object data and code.

All classes support the following SQL operations:

  • CREATE: Creates an instance of the specified class, providing parameters if required. The instance is stored, under a name you specify, in a schema.

  • DROP: Deletes an instance of the specified class.

  • SHOW: Shows a list of instances of the specified class.

An instance of a class can have one or more methods. A method is a stored procedure or function and can be called by using the instance name and method name, and arguments (if any) required by the method. For example, CALL instance_name!method_name(...).
