+Spark SQL defines built-in functions to use, a complete list of which can be
found [here](api/sql/). Among them, Spark SQL has several special categories of
built-in functions: [Aggregate
Functions](sql-ref-functions-builtin-aggregate.html) to operate on a group of
rows, [Array Functions](sql-ref-functions-builtin-array.html) to operate on
Array columns, and [Date and Time
Functions](sql-ref-functions-builtin-date-time.html) to operate on Date and

-Spark SQL is Apache Spark's module for working with structured data.
-This guide is a reference for Structured Query Language (SQL) for Apache
-Spark. This document describes the SQL constructs supported by Spark in detail
-along with usage examples when applicable.
+User-Defined Functions (UDFs) are a feature of Spark SQL that allows users to
define their own functions when the system's built-in functions are not enough
to perform the desired task. To use UDFs in Spark SQL, users must first define
the function, then register the function with Spark, and finally call the
registered function. The User-Defined Functions can act on a single row or act
on multiple rows at once. Spark SQL also supports integration of existing Hive
implementations of UDFs, [...]
