<h1>About SQLite Fiddle <button id='btn-about-close'>close</button></h1>
|
|
|
|
<p>Fiddle is a JavaScript application wrapping a <a href='https://webassembly.org'>WebAssembly</a>
|
|
build of <a href="https://sqlite.org/cli.html">the SQLite CLI shell</a>, slightly
|
|
modified to account for browser-based user input. Aside from the different layout,
|
|
it works just like the CLI shell. This copy was built with SQLite version
|
|
<a id='sqlite-version-link'></a>.
|
|
</p>
|
|
|
|
<p>This app is provided in the hope that it may prove interesting or useful
|
|
but it is not an officially-supported deliverable of the SQLite project.
|
|
It is subject to any number of changes or outright removal at any time.
|
|
That said, for as long as it's online we do respond to support requests
|
|
in <a href="https://sqlite.org/forum">the SQLite forum</a>.
|
|
</p>
|
|
|
|
<p>This app runs on your device. After loading, it does not interact
|
|
with the remote server at all. Similarly, this app does not use any
|
|
HTTP cookies.</p>
|
|
|
|
<p>Fiddle databases are transient in-memory databases unless they
|
|
specifically use a persistent storage option (if available, help
|
|
text in the SQL result output area will indicate how to use
|
|
persistent storage when this app starts up).
|
|
</p>
|

<h1>Usage Summary</h1>
|
|
|
|
<ul>
|
|
<li class='hidden unhide-if-terminal-available'>In "terminal
|
|
mode" it accepts input just like the CLI shell does.</li>
|
|
<li>In split-view mode:
|
|
<ul>
|
|
<li>Input can be executed with either the Run
|
|
button or tapping one of Ctrl-enter or Shift-enter from within
|
|
the text input field. If a portion of the input field is
|
|
selected, only that portion will be run.
|
|
</li>
|
|
<li>The various toggle checkboxes can be used to tweak the layout
|
|
and behaviors. Those toggles are persistent if the JS environment
|
|
allows it.
|
|
</li>
|
|
</ul>
|
|
</li>
|
|
<li class='remove-if-terminal-available'>"Terminal mode" is
|
|
not available in this deployment.
|
|
</li>
|
|
<li>Databases can be imported and exported using the buttons in
|
|
the Options toolbar. No specific limit for imported database
|
|
sizes is imposed, but large databases may cause it to fail with
|
|
an out-of-memory error.</li>
