Hello. I am trying to build an MYSQL query from user input "form" and "dropdown" nodes.
I am using "change" nodes and "join" node to build an array out of 3 inputs that the user needs to give : Device,Item,Serial. Then I use function node to build a query that I will be sending to mysql, however, the function node does not recognise the payload input that I give:
device = msg.payload[0]
item = msg.payload[1]
serial = msg.payload[2]
msg.topic="INSERT INTO pack_to_light (Device,Item,Serial) VALUES ('${device}','${item}',${serial})";
return msg;
Is this not correct way to assign payload array to a function?
The output that I get:
{"payload":"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 '{serial})' at line 1"
For some reason, the problem happens when I try to insert data as integer. It gives me an error even though I have declared "serial" as integer on my database
However, when i change the Serial variable to VARCHAR instead of integer and add brackets, the sql querry works, but it injects the following:
instead of actual payload data, it have injected {device}, {item}, ${serial}
