MySQL Data Logging Issue

reachrao01 · 9 March 2021 02:44

Dear All,
We are trying to insert some data to MySQL - Table but data not adding. Any issue with the following configuration since data logging is not happening. Table showing no records.

Steve-Mcl · 9 March 2021 07:14

You have 6 question marks and only 5 values in the payload.

Also, you don't appear to have connected the function node output to a mySQL node.

First Column is Auto increment.

msg.topic = "insert into tblDB1_Test values (SLNo,?,?,?,?,?,Now(),'Admin')";
msg.payload = [
msg.payload.Word0,
msg.payload.Word2,
msg.payload.Word4,
msg.payload.Word6,
msg.payload.Word8,
]
return msg;

Steve-Mcl · 9 March 2021 07:31

Try msg.topic = "insert into tblDB1_Test values (?,?,?,?,?,Now(),'Admin')
^ 5 question marks to match 5 items in payload

If that doesn't work, include the field names in the insert query.

reachrao01 · 9 March 2021 07:46

msg.topic = "insert into tblDB1_Test (SLNo,Word0,Word2,Word4,Word6,Word8,LastUpdatedOn,LastUpdatedBy) values (SLNo,?,?,?,?,?,Now(),'Admin')";
msg.payload = [
msg.payload.Word0,
msg.payload.Word2,
msg.payload.Word4,
msg.payload.Word6,
msg.payload.Word8,
]
return msg;

Error:
Error: ER_WARN_DATA_OUT_OF_RANGE: Out of range value for column 'Word0' at row 1

As i have said twice now, dont include the auto inc column.

msg.topic = "insert into tblDB1_Test (Word0,Word2,Word4,Word6,Word8,LastUpdatedOn,LastUpdatedBy) values (?,?,?,?,?,Now(),'Admin')";
msg.payload = [
msg.payload.Word0,
msg.payload.Word2,
msg.payload.Word4,
msg.payload.Word6,
msg.payload.Word8,
]
return msg;

When you post an error like this - it is a good idea to include the data going in to the mySQL node so we can see what the value is & have an idea why it might be out of range.

Added but getting the following error. looks like Issue is not with Auto increment number but its related to PARSING.

error: Error: ER_PARSE_ERROR: You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near '?,?,?,?,?,Now(),'Admin')' at line 1

i have another table which has auto increment column. While data inserting, we use SLNO and it is working fine. (Pls refer the below query)

var num = msg.payload
msg.topic = "insert into tblDB1_DBW12 values (SLNo,'DB1.WORD12',"+num+",Now(),'Admin')";
return msg;

Steve-Mcl · 9 March 2021 08:32

what mySQL node are you using? (share a link to it from the flows library )

I dont know about the others but node-red-node-mysql works with prepared statements syntax.

FYI: Building SQL dynamically like this ↑ opens you up to SQL injection

Another attempt...

msg.topic = "insert into tblDB1_Test (Word0,Word2,Word4,Word6,Word8,LastUpdatedOn,LastUpdatedBy) values (?,?,?,?,?,Now(),?)";
msg.payload = [
msg.payload.Word0,
msg.payload.Word2,
msg.payload.Word4,
msg.payload.Word6,
msg.payload.Word8,
'Admin'
]
return msg;

Feed what is going into the sql node into a Debug node set to show Complete message and then show both what is going into the sql node and what is coming out.

Steve-Mcl · 9 March 2021 09:23

well, I am at a loss. Perhaps you are using an old version?

You can drop back to unsafe dynamic SQL

var data = msg.payload;
msg.topic = `insert into tblDB1_Test (Word0,Word2,Word4,Word6,Word8,LastUpdatedOn,LastUpdatedBy) 
                values (${data.Word0},${data.Word2},${data.Word4},${data.Word6},${data.Word8},Now(),'Admin')`;
node.warn(msg.topic); //for debugging - remove me when working!
msg.payload = null;
return msg;

i am using latest version of MySQL.
MariaDB [(none)]> SELECT VERSION();
+---------------------------+
| VERSION() |
+---------------------------+
| 10.3.27-MariaDB-0+deb10u1 |
+---------------------------+

Following are the result.

ERROR:

Steve-Mcl · 9 March 2021 10:07

you did something wrong. that should get changed to ...

insert into tblDB1_Test (Word0,Word2,Word4,Word6,Word8,LastUpdatedOn,LastUpdatedBy) 
                values (1,2,3,4,5,Now(),'Admin');

what nodejs version are you using?

reachrao01 · 9 March 2021 10:08

i tried using both.

msg.topic = "insert into tblDB1_Test (SLNo,Word0,Word2,Word4,Word6,Word8,LastUpdatedOn,LastUpdatedBy) values (SLNo,{data.Word0},{data.Word2},{data.Word4},{data.Word6},${data.Word8},Now(),'Admin')";
msg.topic = "insert into tblDB1_Test (Word0,Word2,Word4,Word6,Word8,LastUpdatedOn,LastUpdatedBy) values ({data.Word0},{data.Word2},{data.Word4},{data.Word6},${data.Word8},Now(),'Admin')";

Results are as follows.

Error: ER_PARSE_ERROR: You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near '{data.Word0},{data.Word2},{data.Word4},{data.Word6},{data.Word8},Now(),'A...' at line 1

Steve-Mcl · 9 March 2021 10:10

Thats not what I told you to do. you have changed the ` backticks to double quotes.

i said...

var data = msg.payload;
msg.topic = `insert into tblDB1_Test (Word0,Word2,Word4,Word6,Word8,LastUpdatedOn,LastUpdatedBy) 
                values (${data.Word0},${data.Word2},${data.Word4},${data.Word6},${data.Word8},Now(),'Admin')`;
node.warn(msg.topic); //for debugging - remove me when working!
msg.payload = null;
return msg;

NOT msg.topic = "insert into tblDB1_Test

See the difference?

I used msg.topic = `insert into tblDB1_Test

even i tried with this...

Steve-Mcl · 9 March 2021 10:24

reachrao01:

even i tried with this...

Well it works for me. It is a valid SQL statement

I did this...

create database Plant;
use Plant;

CREATE TABLE tblDB1_Test (
    SLNo int NOT NULL AUTO_INCREMENT,
    Word0 decimal(10,9),
    Word2 decimal(10,9),
    Word4 decimal(10,9),
    Word6 decimal(10,9),
    Word8 decimal(10,9),
    LastUpdatedOn datetime,
    LastUpdatedBy varchar(100),
    PRIMARY KEY (SLNo)
);

then used this...

[{"id":"cf9f8329.ccd46","type":"function","z":"47169a4b.e85434","name":"","func":"\nvar data = msg.payload;\nmsg.topic = `insert into tblDB1_Test (Word0,Word2,Word4,Word6,Word8,LastUpdatedOn,LastUpdatedBy) \n                values (${data.Word0},${data.Word2},${data.Word4},${data.Word6},${data.Word8},Now(),'Admin')`;\nnode.warn(msg.topic);\nmsg.payload = null;\nreturn msg;","outputs":1,"noerr":0,"initialize":"","finalize":"","x":652,"y":160,"wires":[["f2946f08.114f7","7324a8c6.66c808"]]},{"id":"3c4a55e4.1e54aa","type":"inject","z":"47169a4b.e85434","name":"","props":[{"p":"payload"},{"p":"topic","vt":"str"}],"repeat":"","crontab":"","once":false,"onceDelay":0.1,"topic":"","payload":"{\"Word0\":1,\"Word2\":2,\"Word4\":3,\"Word6\":4,\"Word8\":5}","payloadType":"json","x":482,"y":160,"wires":[["cf9f8329.ccd46"]]},{"id":"7324a8c6.66c808","type":"mysql","z":"47169a4b.e85434","mydb":"9721b43b.2be718","name":"","x":818,"y":160,"wires":[[]]},{"id":"f2946f08.114f7","type":"debug","z":"47169a4b.e85434","name":"","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"true","targetType":"full","statusVal":"","statusType":"auto","x":658,"y":208,"wires":[]},{"id":"9721b43b.2be718","type":"MySQLdatabase","name":"","host":"127.0.0.1","port":"3306","db":"Plant","tz":"","charset":"UTF8"}]
