JdbcConnection (H2 Database Engine wt-1.0.1 API)

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

所有已实现的接口:

AutoCloseable, Connection, Wrapper, JdbcConnectionBackwardsCompat
```
public class JdbcConnection
extends TraceObject
implements Connection, JdbcConnectionBackwardsCompat
```
Represents a connection (session) to a database.

Thread safety: the connection is thread-safe, because access is synchronized. However, for compatibility with other databases, a connection should only be used in one thread at any time.

    Changes the current transaction isolation level. Calling this method will commit an open transaction, even if the new level is the same as the old one, except if the level is not supported.

    - Connection.TRANSACTION_READ_UNCOMMITTED = SET LOCK_MODE 0: no locking (should only be used for testing).
    - Connection.TRANSACTION_SERIALIZABLE = SET LOCK_MODE 1: table level locking.
    - Connection.TRANSACTION_READ_COMMITTED = SET LOCK_MODE 3: table level locking, but read locks are released immediately (default).
    This setting is not persistent. Please note that using TRANSACTION_READ_UNCOMMITTED while at the same time using multiple connections may result in inconsistent transactions.
