<p>This chapter describes the SQL functions and operators supported by Trino. They
allow you to implement complex functionality and behavior of the SQL executed by
Trino operating on the underlying data sources.</p>
<p>If you are looking for a specific function or operator, see the <a class="reference internal" href="functions/list.html"><span class="doc">full
alphabetical list</span></a> or the <a class="reference internal" href="functions/list-by-topic.html"><span class="doc">full list by
topic</span></a>.</p>
<p>Also see the <a class="reference internal" href="language.html"><span class="doc">SQL data types</span></a>
and the <a class="reference internal" href="sql.html"><span class="doc">SQL statement and syntax reference</span></a>.</p>
