从接口复制的说明: Session

Log-off of the MySQL server and close the socket.

指定者:

quit 在接口中 Session

覆盖:

quit 在类中 CoreSession

isClosed

public boolean isClosed()

supportsPreparedStatements

public boolean supportsPreparedStatements()

Check if current session is using a MySQL server that supports prepared statements.

返回:

true if the MySQL server in use supports prepared statements

readyForPreparingStatements

public boolean readyForPreparingStatements()

Check if enough statements were executed in the underlying MySQL server so that another prepare statement attempt should be done.

返回:

true if enough executions have been done since last time a prepared statement failed to be prepared

getNewPreparedStatementId

public int getNewPreparedStatementId(PreparableStatement<?> preparableStatement)

Return an id to be used as a client-managed prepared statement id.

参数:

preparableStatement - PreparableStatement

返回:

a new identifier to be used as prepared statement id

freePreparedStatementId

public void freePreparedStatementId(int preparedStatementId)

Free a prepared statement id so that it can be reused.

参数:

preparedStatementId - the prepared statement id to release

failedPreparingStatement

public boolean failedPreparingStatement(int preparedStatementId,
                                        XProtocolError e)

Propagate to the underlying protocol instance that preparing a statement on the connected server failed.

参数:

preparedStatementId - the id of the prepared statement that failed to be prepared

e - XProtocolError

返回:

true if the exception was properly handled
