Interface Statement

public interface Statement
Object represents an SQL statement.

The statement object is thread-safe.

Statement parameters and query plan can be cached on the server side. The server-side resources are managed automatically. If the server-side state does not exist due to any reason - the very first run, current client node reconnect, cache invalidation, etc. - this state is restored automatically. This may cause the user to experience a slightly increased latency.
