<p>This chapter describes the SQL functions and operators supported by Presto. They
allow you to implement complex functionality and behavior of the SQL executed by
Presto 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 list</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>
