title: Regex (All after first match (without the first match))
body: <p>I am struggling with the easy Regex expression. Basically I want everything after the first match of "_" without the "_".</p>
  
  <p>My current expression is like this: <code>_(.*)</code></p>
  
  <p>When I give input: <code>AAA_BBB_CCC</code></p>
  
  <p>The output is: <code>_BBB_CCC</code></p>
  
  <p>My ideal output would be: <code>BBB_CCC</code></p>
  
  <p>I am using a snowflake database with their build-in regex function. </p>
  
  <p>Unfortunately, I can not use <code>(?&lt;=_).*</code> as it does not support this format of "?&lt;=". Is there some other way how can I modify <code>_(.*)</code> to get the right output?</p>
  
  <p>Thank you. </p>
