    <p>I'm looking for recommendations of a good, free tool for generating sample data for the purpose of loading into test databases. By analogy, something that produces "<a href="http://en.wikipedia.org/wiki/Lorem_ipsum" rel="noreferrer">lorem ipsum</a>" text for any RDBMS. Features I'm looking for include:</p> <ul> <li>Flexibility to generate data for an existing table definition.</li> <li>Ability to generate small and large data sets (> 1 million rows or more).</li> <li>Generate in SQL script format (<code>INSERT</code> statements) or else in a flat file format suitable for bulk import (which is usually faster).</li> <li>A command-line interface for easy scripting.</li> <li>Extensible, open source, written in a dynamic language (these are nice-to-haves, not strong requirements).</li> </ul> <p>PS: I did search for a duplicate question on StackOverflow, but I didn't find one. If there is one, I'll be grateful to get a pointer to it.</p> <hr> <p>Thanks for the great responses everyone! I should amend my requirements that I use Mac OS X as my primary development environment, not Windows (though I did say command-line interface is desirable, and that <em>practically</em> rules out Windows). The Windows-specific suggestions will no doubt be useful to other readers of this question, though, so thanks.</p> <hr> <p>Here is my conclusion:</p> <ul> <li>GenerateData: <ul> <li>PHP web app interface, not command line</li> <li>limited to generating 200 records (or pay $20 for license to generating 5,000 records)</li> </ul></li> <li>RedGate SQL Data Generator <ul> <li>not free, price $295</li> <li>requires Windows, .NET, SQL Server</li> </ul></li> <li>Visual Studio 2008 Database Edition <ul> <li>requires Windows</li> <li>requires costly MSDN or ISV subscription</li> </ul></li> <li>Banner Datadect <ul> <li>not free, price $595</li> <li>requires Windows (?)</li> <li>no support for MySQL (?)</li> <li>GUI, not command line or scriptable</li> </ul></li> <li>Ruby Faker gem <ul> <li>way too slow to use ActiveRecord for bulk data load</li> </ul></li> <li>Super Smack <ul> <li>chiefly a load-testing tool, with a random data generator built in</li> <li>pretty simple to use nevertheless</li> <li>overall a good runner-up tool</li> </ul></li> <li>Databene Benerator <ul> <li>best solution for my needs</li> <li>XML scripts, compatible with DbUnit</li> <li>open source (GPL) Java code</li> <li>command-line usage</li> <li>access many databases directly via JDBC</li> </ul></li> </ul>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
