<p>First we want to create the database schema. For this application only a
single table is needed and we only want to support SQLite so that is quite
easy. Just put the following contents into a file named <cite>schema.sql</cite> in
the just created <cite>flaskr</cite> folder:</p>
<div class="highlight-sql"><div class="highlight"><pre><span class="k">drop</span> <span class="k">table</span> <span class="n">if</span> <span class="k">exists</span> <span class="n">entries</span><span class="p">;</span>
<span class="k">create</span> <span class="k">table</span> <span class="n">entries</span> <span class="p">(</span>
<span class="n">id</span> <span class="nb">integer</span> <span class="k">primary</span> <span class="k">key</span> <span class="n">autoincrement</span><span class="p">,</span>
<span class="n">title</span> <span class="n">string</span> <span class="k">not</span> <span class="k">null</span><span class="p">,</span>
<span class="nb">text</span> <span class="n">string</span> <span class="k">not</span> <span class="k">null</span>
<span class="p">);</span>
</pre></div>
</div>
<p>This schema consists of a single table called <cite>entries</cite> and each row in
this table has an <cite>id</cite>, a <cite>title</cite> and a <cite>text</cite>. The <cite>id</cite> is an
automatically incrementing integer and a primary key, the other two are
strings that must not be null.</p>
