Installation

Prerequisites

The following dependenices must be installed prior to using this node:

• VS Build Tools or VS Community >= v2015 with C++ desktop development workload
• Python3
• Java 8

See Resources for more detail.

Install

Follow the installation guide in the n8n community nodes documentation.

If installing through the n8n GUI fails:

Installing this node through the n8n GUI is throwing an error in my environment currently, node-gyp is unable to find the Visual Studio directory. I will update this section when I find a resolution.

If you also encounter this issue and would still like to help test or use this node, you may try to install it manually by doing the following:

1. Stop n8n if it's currently running

2. Open a new Windows command prompt

3. Navigate to the .n8n/nodes directory

cd [path to .n8n]/.n8n/nodes

4. Use npm to install n8n-nodes-sqldatabase

npm i n8n-nodes-sqldatabase

5. Start n8n

If successful, you should now see the node available in the editor. If you receive any errors during step 4, review them and confirm that you've properly installed/configured or have encountered an issue that I did not. If the node doesn't appear yet installs properly, check that you've added it to the correct .n8n folder for your desired server.
