Haonan Hou commented on IOTDB-999:
----------------------------------
Hi, I tried to write some text code like yours, but I didn't see any IoTDB
problem. Here is the code.
{code:java}
//System.out.println("插入一个 Record，一个 Record 是一个设备一个时间戳下多个测点的数据。");
List<String> measurements = new ArrayList<String>();
List<String> values = new ArrayList<String>();
ArrayList<String> lineList = new ArrayList<String>();
lineList.add("ch1==ch2==ch3==ch4_'1'=='2'=='3'=='4'");
//load the case file,storage the content into ArrayList by line,the case
formate in line is like this ch1==ch2==ch3==ch4_'1'=='2'=='3'=='4',the left of
'_' is sensor and the right of it is value,between sensor is '==',like the
value.
for (int i = 0; i< lineList.size(); i++) {
String[] tag_attribute = lineList.get(0).split("_");
//split the lineList and storage into a string array.
String[] senName = tag_attribute[0].split("==");
for (int j = 0; j< senName.length; j++) {
measurements.add(senName[j]);
}
String[] val = tag_attribute[1].split("==");
for (int j=0; j < val.length; j++) {
values.add(val[j]);
}
}
insert1("root.sg.d1", measurements, values); //arg[3]是设备ID，不加root.的部分。
public static void insert1(String deviceId,List<String> measurements,
List<String> values) {
Date dt= new Date();
long timeseries = dt.getTime();
try {
System.out.println("begin session.insertRecord 写入");
session.insertRecord(deviceId, timeseries, measurements, values);
//there is no error tip in log and no record be inserted.
System.out.println("end session.insertRecord 写入");
} catch (IoTDBConnectionException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (StatementExecutionException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
}
{code}
And the result is as below:

Your issue is probably because your data format. Try to catch all exception may
help you to find the reason. :)
> insert record into the database use session.insertRecord ,there is no error
> tip in log and no record be inserted.
