Insert array contents into MSSQL table

jomacdon · 13 July 2020 14:14

Hello, may I please ask for some guidance... I have an array of data I want to insert into my MSSQL table called 'MyTable', here is the statement I have created:

INSERT INTO [MyTable] (id, device_id, label, message, severity, activated_time, cleared_time) VALUES ('{{{payload.object.id}}}', '{{{payload.object.deviceId}}}', '{{{payload.object.label}}}', '{{{payload.object.message}}}', '{{{payload.object.serverity}}}', '{{{payload.object.activatedTime}}}', '{{{payload.object.clearedTime}}}')

Here is a screen shot of my Flow:

I think the following is going into my SQL Node:

13/07/2020, 14:12:52node: bb71a7c8.4d6348
msg.payload : array[2]
array[2]
0: object
id: "49cd2d85-0e12-4147-8bfa-444eb43d7a4e"
deviceId: "a03394b0-9a49-45c7-afb4-07541a8aba47"
label: "Handle Alarmed"
message: "Rack Door Handle alarmed for sensor Back Door at NBRK0750 with state "
severity: "CRITICAL"
activatedTime: "2020-06-19T10:38:24.199Z"
1: object
id: "9dadad16-38fe-4ee8-9f65-ada755a97e10"
deviceId: "acb8c96e-db30-4b72-bd06-ab8706b43efd"
label: "Local Authorization Alarm"
message: "Local Authorization alarm for Back Door at NBRK0750"
severity: "INFO"
activatedTime: "2020-04-29T14:28:57.594Z"

Thank you!

can you attach a debug node (set to show complete message) to the output of the MSSQL node

I need to see the all the msg values (in particular the SQL generated by the mustache)

jomacdon · 13 July 2020 14:45

Hello again Steve-Mcl Here is the result of the debug node:

Here is my SQL table when it fails:

Thank you.

Colin · 13 July 2020 14:58

I wonder what that error means. Have you tried googling for it?

Steve-Mcl · 13 July 2020 15:01

I guess you are not using node-red-contrib-mssql-plus

when you use that node (apart from the many bug fixes & additional features) you get the compiled SQL statement in the debug output to help you see what is going wrong.

If you wish to upgrade...

stop node-red
open a command line prompt & CD to your node-red folder
npm uninstall node-red-contrib-mssql (or which ever derivative you are using)
npm install node-red-contrib-mssql-plus
start node-red

Steve-Mcl · 13 July 2020 15:04

Colin, i suspect the values are not being rendered into his SQL Statement (I suspect the duplicate violation is a red herring - and why I am asking him to install mssql-plus as it gives you the rendered SQL statement in the output msg object to see what is actually being executed against the SQL Server)

Colin · 13 July 2020 15:05

That makes sense.

jomacdon · 13 July 2020 15:06

Hi Steve-Mcl, I am actually using the 'node-red-contrib-mssql-plus' node:

Steve-Mcl · 13 July 2020 15:06

where did you attach the debug?

can you share your flow

```
like this
```

and a screen shot

jomacdon · 13 July 2020 15:08

Here is the Flow:

jomacdon · 13 July 2020 15:09

Steve-Mcl · 13 July 2020 15:10

Yeah - you need to show complete message option set on the debug node

Try again please.

jomacdon · 13 July 2020 15:15

Here is the debug output now:

13/07/2020, 16:13:17node: 734d2b68.1ad644

_msgid: "6a91ebff.7d9cb4"
query: "INSERT INTO [MyTable] (id, device_id, label, message, severity, activated_time, cleared_time) VALUES ('', '', '', '', '', '', '')↵"

and a new screen shot:

Steve-Mcl · 13 July 2020 15:20

So as you can see - all of your values are empty

so the duplicate violation is occurring because you are always putting empty strings in the database.

Since your SQL is...



INSERT INTO [MyTable] (id, device_id, label, message, severity, activated_time, cleared_time) 
VALUES ('{{{payload.object.id}}}', '{{{payload.object.deviceId}}}', '{{{payload.object.label}}}', '{{{payload.object.message}}}', '{{{payload.object.serverity}}}', '{{{payload.object.activatedTime}}}', '{{{payload.object.clearedTime}}}')

... check the output of the template node Place each into X - does it have properties in payload.object.deviceId and payload.object.id etc?

jomacdon · 13 July 2020 15:40

Hi, thanks for your patience
Here is another screen shot showing the original output and then after the Split & Template:

I tested the output from the debug node looking for 'payload.object.id' as you suggested and I get nothing:

jomacdon · 13 July 2020 15:45

Inside Split No.1 I have two Objects in the Array, each has a key identifier with a corresponding value, it's these values I would like to Inject into my SQL table.

Steve-Mcl · 13 July 2020 15:46

your split isnt working.

Can you paste a copy (using the debug copy button) of the data from the API node

```
paste copy from debug like this
```

jomacdon · 13 July 2020 15:51

Hi Steve-Mcl, thanks! Here is the debug output from the API call:

Steve-Mcl · 13 July 2020 15:54

I cant do anything with that data.

Can you do exactly what I asked & I will see if I can make this work for you by "faking the API call" (since i dont have access to the API, I need ACTUAL data - not a bunch of strings saying [0 … 9])

^ PRESS THE COPY BUTTON - PASTE INTO REPLY

jomacdon · 13 July 2020 15:59

Sorry - still getting to grips with this...

I got an error with the size of the reply (Body is limited to 32000 characters; you entered 94735.)

Here is the output after the filter node instead:
