JdbcConnection (H2 Database Engine 2.0.0 API)

java.lang.Object
- org.h2.message.TraceObject
- - org.h2.jdbc.JdbcConnection

所有已实现的接口:

AutoCloseable, Connection, Wrapper, CastDataProvider, JdbcConnectionBackwardsCompat
```
public class JdbcConnection
extends TraceObject
implements Connection, JdbcConnectionBackwardsCompat, CastDataProvider
```
Represents a connection (session) to a database.
Thread safety: the connection is thread-safe, because access is synchronized. Different statements from the same connection may try to execute their commands in parallel, but they will be executed sequentially. If real concurrent execution of these commands is needed, different connections should be used.
