All Implemented Interfaces:

CommandHandler

public class CreateTableHandler
extends Object
implements CommandHandler

Handles CREATE TABLE (plain, CLONE, and CREATE TABLE AS SELECT), extracted from DDLCommandHandler, which keeps the CREATE dispatch and delegates here. Column parsing is delegated to ColumnDefinitionParser; shared schema/name helpers are reached via the ddl back-reference.
