Hi <br />
I have the following query<br />

<pre><code class="code-1 nolinks" id="code-10-29078751-1"><span>select min(odometer) as odometer_min, max(odometer) as odometer_max</span>
<span>From dbo.MyTable</span>
<span>Where gpsDateTime &gt;= '2018-01-01' and gpsDateTime &lt; '2018-01-18' and eventID = 1</span>
</code></pre>
<br />
this returns 2 values<br />
<br />
What i actually need to do is return the difference between the min and max <br />
<br />
What would the sql be for this
