NVIDIA Nsight Systems data exported in SQLite format.</p>
<div class="section" id="general-notes">
<h2>General notes<a class="headerlink" href="#general-notes" title="Permalink to this headline">¶</a></h2>
<p>The data exported into SQLite database don’t contain any indexes by default and
are as close to the contents of the report as possible. Therefore, for better
readability and speed of execution, queries below will alter tables.</p>
</div>
<div class="section" id="common-helper-commands">
<h2>Common helper commands<a class="headerlink" href="#common-helper-commands" title="Permalink to this headline">¶</a></h2>
<p>When utilizing <cite>sqlite3</cite> commandline tool, it’s helpful to have data printed
as named columns, this can be done with:</p>
<div class="highlight-default"><div class="highlight"><pre><span></span><span class="o">.</span><span class="n">mode</span> <span class="n">column</span>
<span class="o">.</span><span class="n">headers</span> <span class="n">on</span>
</pre></div>
</div>
<p>Default column width is determined by the data in the first row of results. If
this doesn’t work out well, you can specify widths manually:</p>
<div class="highlight-default"><div class="highlight"><pre><span></span><span class="o">.</span><span class="n">width</span> <span class="mi">10</span> <span class="mi">20</span> <span class="mi">50</span>
