Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

n8n-nodes-sap-connections

v1.0.3

Published

n8n community node to connect and query SAP HANA databases

Readme

n8n-nodes-sap-connections

Nodo personalizado de n8n para conectarse a SAP HANA usando @sap/hana-client.

Credenciales

Crea una credencial SAP HANA API (GS) con:

  • Server / IP: ejemplo 172.20.10.36
  • Port: ejemplo 30241
  • User: ejemplo BI_AZURE_PRD
  • Password: password del usuario SAP HANA

El nodo arma internamente serverNode como server:port.

Uso

  1. Agrega el nodo SAP HANA - GS.
  2. Selecciona la credencial SAP HANA.
  3. Selecciona el esquema desde el campo Schema.
  4. Escribe la consulta SQL en SQL Query.

Ejemplo:

SELECT TOP 10
  AUFNR,
  EQUNR,
  ILART,
  IWERK,
  CURRENT_TIMESTAMP AS etlTimestamp
FROM AFIH
WHERE MANDT = 100
  AND EQUNR IS NOT NULL

El nodo ejecuta SET SCHEMA "<schema>" antes de correr la consulta, por eso puedes consultar tablas del esquema seleccionado sin prefijarlas.

Instalacion local en n8n self-hosted

Desde esta carpeta:

npm install
npm run build
npm pack

Luego instala el .tgz generado en tu instancia self-hosted de n8n o dentro de ~/.n8n/nodes, segun tu forma de despliegue.

Validacion de credenciales

La validacion intenta conectarse a SAP HANA y ejecuta:

SELECT CURRENT_USER AS USER_NAME, CURRENT_SCHEMA AS SCHEMA_NAME FROM DUMMY

Si la conexion falla, el nodo devuelve un error indicando que se revisen server, puerto, usuario y password.
