# Overview

> DuneSQL supports a wide range of built-in functions and operators.

This chapter describes the built-in 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.

Table procedures such as Datashare syncs are documented under [Supported SQL Operations](/api-reference/connectors/sql-operations), not in this functions reference.

Using `SHOW FUNCTIONS` in the query editor returns a list of all available functions, including custom functions, with all supported arguments and a short description.
