Database fiddle sites

I knew there was JSFiddle for live playing around with JavaScript and more in your browser, so I wondered if there was a similar site for databases and SQL queries.

There are, so here are a few database fiddle sites: SQL playgrounds where you can live play with SQL queries (sometimes even without an underlying example database).

All via [Wayback/Archive.is] database fiddle – Google Search:

1. [Wayback/Archive.is] dbfiddle

   (

   • runs DB2, Firebird, MariaDB, MySQL, Oracle, Postgres, SQLite, SQL Server, Yugabyte, often even multiple versions;
   • fiddles with SQL Server 2019 can be created on top of the [Wayback/Archive.is] AdventureWorks sample database;
   • fiddles are automatically saved under a GUID URL on first run for easy sharing;
   • has a markdown export for embedding into for instance Stack Exchange questions/answers;
   • supplied by [Wayback/Archive.is] Expert DBA Help Now;
   • a very old version of the back-end source code is at [Wayback/Archive.is] jackdouglas/dbfiddle;
   • twitter account is [Wayback/Archive.is] db⟨⟩fiddle (@dbfiddleuk) | Twitter and still active

   ) which I  used for these examples to include in the post tomorrow:

   • [Wayback/Archive.is] SQL Server 2019 | dbfiddle: select a b, c from (values (9, 1, 2), (8, 3, 4), (7, 5, 6)) t(a, b, c) order by b
   • [Wayback/Archive.is] SQL Server 2019 | dbfiddle: select a, b, c from (values (9, 1, 2), (8, 3, 4), (7, 5, 6)) t(a, b, c) order by b

   Note the above code makes uses of a [Wayback/Archive.is] Table Value Constructor (Transact-SQL) – SQL Server | Microsoft Docs which has more examples in [Wayback/Archive.is] SQL SERVER – Creating Dataset Using VALUES Clause Without Creating A Table – SQL Authority with Pinal Dave.

2. [Wayback/Archive.is] DB Fiddle – SQL Database Playground

   (

   • supports MySQL, Postgres, SQLite
   • supplied by [Wayback/Archive.is] Status200 – Web Application and Digital Product Development (like dbfiddle: also from the UK);
   • twitter account is [Archive.is] DB Fiddle (@db_fiddle) | Twitter and is active a few times per year

   )

3. [Wayback/Archive.is] SQL Fiddle

   (

   • supports MySQL, Oracle, Postgres, SQLite, SQL Server, with Postgres in two versions;
   • requires to create a schema first, which makes it a lot harder to use than the other two;
   • runs on insecure http by default;
   • according to [Wayback/Archive.is] SQL Fiddle supplied by [Wayback/Archive.is] ZZZ Projects | Adding value to the .NET Community with source code at [Wayback/Archive.is] zzzprojects/sqlfiddle3: New version based on vert.x and docker;
   • twitter account is [Archive.is] sqlfiddle (@sqlfiddle) | Twitter, but has not been active since 2018
