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 🙏

Readme

node-red-contrib-sqldbs

Node-RED nodes to work with a database that can be either MSSQL, MySQL, SQLite, or PostgreSQL server.

Install

Install from npm

npm install node-red-contrib-sqldbs

Usage

This package contains one node to select, update, insert, or delete records from a specified database engine. It can work with Microsoft SQL Server, MySql, SQLite, and ProgreSQL by selecting proper database dialect

Query node usage:

You will need to fill in the following fields:

-- Database host name.

-- User name to access the database.

-- Password for the user name above.

-- Database name

-- Dialect for different database engines, currently, it supports MSSQL, MYSQL, SQLite, and PostgreSQL.

-- Query Type that the query is for. It can be either select, insert, update, and delete

Node usage:

The returned data will be stored in msg.payload and it will contains two array.
You should just need to access the first object of the array to retrieve data returned from the database query.

So for example, you might create a function node that flows into your sqldbs node with code like this to find if the user exists in the table (please make a special note to "as count". It will serve as the key of the return to retrieve the data. However, if you use "select * from user", the column name will serve as the key name):

msg.topic = "select count(*) as count from user where username = '" + msg.payload.username + "'";
return msg;

Then, you can use a switch function after sqldbs node to check if the user exist:

if msg.payload[0][0].count > 0 
if msg.payload[0][0].count <= 0

Currently, only MSSQL server database have been tested but not others. Please let me know if you have any issue.
