[WayBack] showthedocs

is a documentation browser that finds the relevant docs for your code. It works by parsing the code and connecting parts of it to their explanation in the docs

, and supports these languages:

  • SQL
    • postgresql
    • mysql
  • Configuration
    • nginx
    • gitconfig

You can enter any language text, then click the language, followed by clicking the “SHOW ME THE DOCS!” button, for which an example is further below.

The site has an open architecture, allowing to plug in more languages and documentation:

 

gitconfig example

So for instance the below ./git/config file leads to this result [WayBack] where you can click on all the coloured areas for easy navigation through the documentation:

Public database servers

Posted by jpluimers on 2019/10/30

I could not find any vendors/architectures have public database servers.

So there is no good way to go beyond SQLFiddle (of which I wrote before in SQL Fiddle | A tool for easy online testing and sharing of database problems and their solutions and David Rodriguez: a few nice posts on SQL (via: Google+)), that does not provide database access, but allows you to fire SQL statements onto these architectures:

  • MySQL 5.6
  • Oracle 11g R2
  • PostgreSQL 9.6
  • PostgreSQL 9.3
  • SQLite (WebSQL)
  • SQLite (SQL.js)
  • MS SQL Server 2017

I get the thing (it is very hard to secure an “over the internet” connection to a database server; do NOT do this: [WayBack] connectivity – Connect to SQL Server over Internet – Database Administrators Stack Exchange), so the alternative is to run locally.

If you run locally, there are plenty of example/demo database, like:

SQL Fiddle | A tool for easy online testing and sharing of database problems and their solutions.

Posted by jpluimers on 2019/08/29

Via [WayBack] SQL select only rows with max value on a column, I bumped into http://sqlfiddle.com/#!9/a6c585/1:

Application for testing and sharing SQL queries.

Source: [WayBackSQL Fiddle | A tool for easy online testing and sharing of database problems and their solutions.

It is a cool site, currently supporting these SQL back-ends:

  • MySQL 5.6
  • Oracle 11g R2
  • PostgreSQL 9.6
  • PostgreSQL 9.3
  • SQLite (WebSQL)
  • SQLite (SQL.js)
  • MS SQL Server 2014

You can host it yourself using [WayBack] GitHub – zzzprojects/sqlfiddle2: New version of SQL Fiddle based on OpenIDM (in the past it was [WayBack] GitHub – zzzprojects/sqlfiddle)

Other resources for learning and playing around with SQL:
