[jira] [Created] (IOTDB-3894) In the case that the template is used, the latest query result is incorrect
suchenglong created IOTDB-3894:
----------------------------------
Summary: In the case that the template is used, the latest query result is incorrect
Key: IOTDB-3894
URL: https://issues.apache.org/jira/browse/IOTDB-3894
Project: Apache IoTDB
Issue Type: Bug
Affects Versions: 0.13.1-SNAPSHOT
Reporter: suchenglong
使用模板的情况下，最新点查询查询结果不正确.
场景如下:
创建存储组：root.clsu1
创建模板： t1(s1,int32),
该模板挂载到root.clsu1
插入一个实体和物理量
insert into root.clsu1.device1(time,s1) values (220,200)
插入另一个实体和物理量
insert into root.clsu1.device2(time,s1) values (320,200)
查询最新点数据，发现结果为device1的数据
select last s1 from root.clsu1.device2
结果示例：
IoTDB> select last s1 from root.clsu1.device1
+-----------------------------+---------------------+-----+--------+
| Time| timeseries|value|dataType|
+-----------------------------+---------------------+-----+--------+
|1970-01-01T08:00:00.220+08:00|root.clsu1.device1.s1| 200| INT32|
+-----------------------------+---------------------+-----+--------+
Total line number = 1
It costs 0.007s
IoTDB> select s1 from root.clsu1.device2
+-----------------------------+---------------------+
| Time|root.clsu1.device2.s1|
+-----------------------------+---------------------+
|1970-01-01T08:00:00.320+08:00| 200|
+-----------------------------+---------------------+
Total line number = 1
It costs 0.012s
IoTDB> select last s1 from root.clsu1.device2
+-----------------------------+---------------------+-----+--------+
| Time| timeseries|value|dataType|
+-----------------------------+---------------------+-----+--------+
|1970-01-01T08:00:00.220+08:00|root.clsu1.device2.s1| 200| INT32|
+-----------------------------+---------------------+-----+--------+
