方法详细资料

getId

int getId()

Returns the query id used when profiling

返回:

id

setCancelStatus

getBatchedArgs

List<Object> getBatchedArgs()

Get the batched args as added by the addBatch method(s). The list is unmodifiable and might contain any combination of String, ClientPreparedQueryBindings, or ServerPreparedQueryBindings depending on how the parameters were batched.

getTimeoutInMillis

int getTimeoutInMillis()

setTimeoutInMillis

void setTimeoutInMillis(int timeoutInMillis)

setExecuteTime

void setExecuteTime(long executeTime)

getExecuteTime

long getExecuteTime()

Returns the elapsed time for the server to execute the query.

返回:

the time it took for the server to execute the query.

startQueryTimer

                                int timeout)

getStatementExecuting

AtomicBoolean getStatementExecuting()

getCurrentDatabase

String getCurrentDatabase()

setCurrentDatabase

void setCurrentDatabase(String currentDb)

isClearWarningsCalled

boolean isClearWarningsCalled()

setClearWarningsCalled

void setClearWarningsCalled(boolean clearWarningsCalled)

statementBegins

stopQueryTimer

void stopQueryTimer(CancelQueryTask timeoutTask,
                    boolean rethrowCancelReason,
                    boolean checkCancelTimeout)
