+### Description
+The `DROP FUNCTION` statement drops a temporary or user defined function (UDF). An exception will
+ be thrown if the function does not exist.
+
+### Syntax
+{% highlight sql %}
+DROP [TEMPORARY] FUNCTION [IF EXISTS] [db_name.]function_name;
+{% endhighlight %}
+
+
+### Parameters
+
+
+ function_name
+ - The name of an existing function.
+
+
+
+ TEMPORARY
+ - Should be used to delete the `temporary` function.
+
+
+
+ IF EXISTS
+ - If specified, no exception is thrown when the function does not exist.
+
+
+### Example
+{% highlight sql %}
+-- Create a permanent function `test_avg`
+CREATE FUNCTION test_avg as 'org.apache.hadoop.hive.ql.udf.generic.GenericUDAFAverage';
+
+-- List user functions
+SHOW USER FUNCTIONS;
+ +-------------------+
+ | function |
+ +-------------------+
+ | default.test_avg |
+ +-------------------+
+
+-- Create Temporary function `test_avg`
+CREATE TEMPORARY FUNCTION test_avg as 'org.apache.hadoop.hive.ql.udf.generic.GenericUDAFAverage';
+
+-- List user functions
+SHOW USER FUNCTIONS;
+ +-------------------+
+ | function |
