"Error: SQLITE_ERROR: no such column: undefined"

ScheepersJohan · 7 April 2020 08:57

Hi,

My sqlite put this error out - "Error: SQLITE_ERROR: no such column: undefined"

Statement to sqlite -
topic: "INSERT INTO sensor_data (id,device,value,epoch) VALUES ('28-02131a935aa','watertemp',20.3,1586247316916)"
_msgid: "b4b66b3f.f93918"

This statement come from a function node whit the following:

sql = "INSERT INTO sensor_data (id,device,value,epoch) " +
"VALUES ('28-02131a935aa','watertemp',"+msg.watertemperature+","+epoch+")";
outputs.push({topic:sql});

But if i check my DB the data are written to it.

Any help will be appreciated.

What is the schema for the table? (in CLI start sqlite and issue .fullschema)

ScheepersJohan · 7 April 2020 10:10

sqlite> .fullschema
CREATE TABLE sensor_data (
id INTEGER NOT NULL,
device TEXT,
sensor TEXT,
value REAL,
epoch INTEGER,
timestamp INTEGER DEFAULT CURRENT_TIME

Which node are you using for the sqlite? i just tested with your schema and insert and it worked fine using the node-red-node-sqlite v0.4.3

ScheepersJohan · 7 April 2020 11:44

I amusing node-red-node-sqlite 0.4.3, the same version.

The strange thing it throws the error but still wights it to the DB (so all the data is there).

It is annoying seeing in the Debug these messages.

zenofmud · 7 April 2020 11:48

can yu provide your complete flow (read this first) and I'll take a look

Also, what platform are you running on? Pi?, Mac? in? and what OS/version

ScheepersJohan · 7 April 2020 11:54

Running on a PI, have update every thing this morning.

I think the first thing to do is to add a debug node showing what is going into the sql node. Set the debug node to Show Complete Message. Then you will see exactly what query is being sent to the node.

ScheepersJohan · 7 April 2020 12:36

Hi,

This is form the debug node.

Colin · 7 April 2020 12:39

id should be an integer.

ScheepersJohan · 7 April 2020 12:59

Modified my db now that ID are text - it still throws the same error

CREATE TABLE sensor_data (
id TEXT,
device TEXT,
sensor TEXT,
value REAL,
epoch INTEGER,
timestamp INTEGER DEFAULT CURRENT_TIME
);

The data do go int the DB

zenofmud · 7 April 2020 13:02

Stick a debug node (set to display complete msg object) on the output of your 'Save to DB' function node and look at the output.

What do you see in the debug(s)?

zenofmud · 7 April 2020 13:21

Have you changed that function since you posted the flow? Because I'm seeing two output msg's for each input.

sql = "INSERT INTO sensor_data (id, device,value,epoch) " +
        "VALUES ('28-02131a935aa','watertemp',"+msg.watertemperature+","+epoch+")";
outputs.push({topic:sql});
sql = "INSERT INTO sensor_data (id,device,value,epoch) " +
        "VALUES ('28-00006c7f31d','airtemp',"+msg.airtemperature+","+epoch+")";
outputs.push({topic:sql});

Is that code still in our function?

ScheepersJohan · 7 April 2020 13:26

Yes I have two, they are identical in the sens as how they are processes, but two different sensors, different ID and different device.

Both give the same error.

ScheepersJohan · 7 April 2020 13:55

Found the problem:

Each sensor generates a flow, so each sensor triggers two flows from fx"Save to DB" to sqlite, as there are two statements outputo for each flow out into the fx"Save to DB" (four flows in total between fx"Save to DB" and sqlite) one flow for sensor now missing its value.

To fix it I need to put a join node, one flow into fx"Save to DB" with both two sensor data in it "msg.watertemperature" and "msg.airtemperature"

Thank you for your help, really appreciate it

The moral is, when you post debug output here, make sure that the output you post corresponds to the error situation.

ScheepersJohan · 7 April 2020 17:30

I did not notice there were 4 debugs cumming from the 2 flows, 2 from the messages of the sensors and two error messages, so quit a few information at one time. That is were it were not to easy to pic up the correct information, I try always to be as thorough to provide information so the issues can be solve as easily as possible.

@Colin and @zenofmud thanks for your assistance, greatly appreciated
