How to get date_diff from previous rows in Presto?
<p>I'm trying to get a <code>diff_date</code> from Presto from this data. </p>

<pre><code>timespent | 2016-04-09T00:09:07.232Z | 1000          | general
timespent | 2016-04-09T00:09:17.217Z | 10000         | general
timespent | 2016-04-09T00:13:27.123Z | 250000        | general
timespent | 2016-04-09T00:44:21.166Z | 1144020654000 | general
</code></pre>

<p>This is my query</p>

<pre><code>select _t, date_diff('second', from_iso8601_timestamp(_ts), SELECT from_iso8601_timestamp(f._ts) from logs f 
              where f._t = 'timespent'
               and f.dt = '2016-04-09'
               and f.uid = 'd2de01a1-8f78-49ce-a065-276c0c24661b'
               order by _ts)
from logs d
where _t = 'timespent'
and dt = '2016-04-09'
and uid = 'd2de01a1-8f78-49ce-a065-276c0c24661b'
order by _ts;
</code></pre>

<p>This is the error I get</p>

<pre><code>Query 20160411_150853_00318_fmb4r failed: line 1:61: no viable alternative at input 'SELECT'
