ERROR：合并类型BYTEA和时间戳没有时区不能匹配

我试图运行此查询，但我得到这个错误：ERROR：合并类型BYTEA和时间戳没有时区不能匹配

ERROR: COALESCE types bytea and timestamp without time zone cannot be matched

我想这个问题是在这条线：

COALESCE(:last_timestamp,date_trunc('hour', timestamp '1969-01-01 00:00:00.000000'))

参数：

:last_timestamp

可以为NULL，这就是为什么我这样的情况下

@Query(value="SELECT\n" + 
     " id,\n" + 
     " wristband_records_processed.device_id as deviceId,\n" + 
     " user_id as userId,\n" + 
     " rssi,\n" + 
     " record_timestamp as locationTimestamp,\n" + 
     " beacon_id as beaconId,\n" + 
     " locatable_devices.locatable_type as locatableType,\n" + 
     " coalesce(EXTRACT(EPOCH FROM (record_timestamp - lag(record_timestamp) OVER(order by record_timestamp))),0)as duration\n" + 
     " FROM wristband_records_processed\n" + 
     " LEFT JOIN locatable_devices on locatable_devices.device_id = wristband_records_processed.beacon_id\n" + 
     "where user_id = :userId and record_type != 'HANDWASH'\n" + 
     "  and rssi >= -85 AND locatable_type != 'UNKNOWN' AND wristband_records_processed.record_timestamp> COALESCE(:last_timestamp,date_trunc('hour', timestamp '1969-01-01 00:00:00.000000')) \n " + 
     "OFFSET :offset LIMIT :limit ;", nativeQuery = true)

感谢您的帮助

我试过很多的铸造方法，但其中不适合我 –

工作在哪里在Spring代码中定义并设置last_timestamp？ –

如果它只是类型，而不是值 - 试试'COALESCE（：last_timestamp :: text :: timestamptz'或甚至'COALESCE（to_timestamp（：last_timestamp :: text）:: timestamptz' –

只是让他们同样

COALESCE(date_trunc('hour', :last_timestamp), 
     date_trunc('hour', timestamp '1969-01-01 00:00:00.000000'))

或

COALESCE(:last_timestamp, timestamp '1969-01-01 00:00:00.000000')

同样的错误...不为我工作 –
