Перевод декорирование таблицы
Описание With the AS OF SQL clause, you can choose different snapshots for each table in the query. Associating a snapshot with a table is known as ~. If you do not decorate a table with a snapshot, then a default snapshot is used for it. Suppose you want to write a query to find all the new customer accounts created in the past hour. You could do set operations on two instances of the same table decorated with different AS OF clauses. See decorate a table.
