Bulk insert does not work.

[belgianbeer]

I installed Nod-RED with node-red-contrib-mssql-plus.

After installed node-red-contrib-mssql-plus, I tested the "Bulk demo.json". (BTW, this example looks not in module. I got it from repository of Github.)

"Create demo_device_parameters_table" and "Drop demo_device_parameters_table" work well. But inject "raws:1000" has error. Here is error message.

11 Sep 10:46:51 - [error] [MSSQL:bulk insert -> demo_device_parameters_table] Invalid string.

Simple INSERTs and SELECTs are working fine.

My environment as follows.

• Debian 12 (Linux 6.1.0-11, VM on Azure)
• Azure SQL Database
• Node.js version: v18.13.0
• Node-RED version: v3.1.0

Am I misunderstanding something?

Works for me

https://github.com/bestlong/node-red-contrib-mssql-plus/assets/44235289/7bd35c59-718e-4d13-8f8d-535b01cd4020

Unfortunately, I do not have access to an azure DB so I used a linux docker image

[belgianbeer]

I created another server (not on Azure) and prepared a docker environment. So I started the docker version of Node-RED and tested it. After starting Node-RED docker, I added "node-red-contrib-mssql-plus" and loaded and executed the demo. "Create demo_device_parameters_table" and "Drop demo_device_parameters_table" worked fine. But "bulk insert -> demo_device_parameters_table" gave the same error.

I created another server (not on Azure)

Can you link to the exact image you used please

[belgianbeer]

I used the following command line when starting Node-RED:

docker run -it -p 1880:1880 -v node_red_data:/data --name mynodered nodered/node-red

It's probably https://hub.docker.com/r/nodered/node-red

I used the following command line when starting Node-RED:

docker run -it -p 1880:1880 -v node_red_data:/data --name mynodered nodered/node-red

I was referring to Azure:

I created another server (not on Azure)

Can you link to the exact image you used please

as in when you created ANOTHER SERVER - which docker image did you use?

EDIT:

I am re-reading this again - I may be mixed up.

Are you STILL testing against the original DB (i.e. did you simply create another Node-RED) OR Did you create and test the first failing Node-RED instance against a different Azure/SQL Server?

---

However: Since I ss you are also using docker for Node-RED, that may be part of the problem. Are you in a position to test the bulk demo against your Azure DB with node-red running natively/on metal?

[belgianbeer]

I will sort out the situation.

First reported configuration:

• I created a new Azure VM and Azure SQL Database.
• The VM Image is Debian 12 "Bookworm".
• SQL Database is configured without domain authentication.
• The VM installed nodejs with apt after starting Debian.
• I installed npm with apt.
• I installed Node-RED using npm. (npm install --unsafe-perm --global Node-RED)
• The other thing I did was install nginx and configure Node-RED with a reverse proxy for SSL.
• I installed node-red-contrib-mssql-plus after starting Node-RED.
• I did a test.

Second reported configuration:

• I prepared one more new Azure SQL Database for testing.
• SQL Database is set to not perform domain authentication.
• I had a Debian 11 VM on my office server that I usually use, so I installed Docker on it.
• I ran a Node-RED Docker image.
• I installed and tested node-red-contrib-mssql-plus after starting Node-RED.

I can also set up a metal server if needed. I'm thinking of using the first configuration in the project I'm currently working on, so I'd really like to resolve any issues with node-red-contrib-mssql-plus.

• I had a Debian 11 VM on my office server that I usually use, so I installed Docker on it.

It would be very useful to know if you could install Node-RED on the VM (this should work as "on metal") and try again.

And since your VM is Debian, can I ask that you install Node-RED using the official installer script with --node18 appended to the command. see here: https://nodered.org/docs/getting-started/raspberrypi#installing-and-upgrading-node-red

[belgianbeer]

I have prepared a Debian Bullseye metal server. After that I installed nodejs 18.18. I installed Node-RED using the Raspberry Pi script in that URL. I ran the same test after starting Node-RED and got the same error regarding bulk insert. I will continue to try changing the nodjs version to 16.

[belgianbeer]

It worked! But, It wat not my mistake. The example was bad. If I use the sample as is, the type of the fifth parameter in the bulk insert flow was NVarChar(200). But I think this should be a Float.

[belgianbeer]

I created a pull request for fix this issue.

Thank you!
