BasicDaoImpl

@Autowired
public BasicDaoImpl(org.springframework.jdbc.core.JdbcTemplate jdbcTemplate)

方法详细资料

getMetaData

public List<String> getMetaData()

指定者:

getMetaData 在接口中 BasicDao

setTimestampRadioX

public static void setTimestampRadioX(String timestampPrecision)

querySeries

public List<TimeValues> querySeries(String s,
                                    org.apache.iotdb.tsfile.utils.Pair<ZonedDateTime,ZonedDateTime> timeRange)

Note: If the query fails this could be due to AGGREGATIION like AVG on booleayn field. Thus, we then do a retry with FIRST aggregation. This should be solved better in the long run.

指定者:

querySeries 在接口中 BasicDao

querySeriesInternal

public List<TimeValues> querySeriesInternal(String s,
                                            org.apache.iotdb.tsfile.utils.Pair<ZonedDateTime,ZonedDateTime> timeRange,
                                            String function)
