title: Prometheus QL get the first values from the query result
body: <p>I write the query below to get the up time for the microvices.</p>
  <p><code>base_jvm_uptime_seconds{kubernetes_name=&quot;namepspce1&quot;}</code></p>
  <p>However, it returns multiple values, so the grafana returns &quot;Only queries that return single series/table is supported&quot;. I am wondering how can I the first velus from the query result?</p>
  <p>I tried <code>base_jvm_uptime_seconds{kubernetes_name=&quot;namepspce1&quot;}[0]</code>, but it doesn't work..</p>
  <p>Thanks!</p>
