Finds the host value from a valid URL. Input values must be of URL or String type and can be literals or column references.

In this implementation, a host value includes everything from the end of the protocol identifier (if present) to the end of the extension (e.g. .com).

URL literal examples:

derive type:single value: HOST('http://www.example.com' ) as: 'myHost'

Output: Generates a column containing the value www.example.com

Column reference example:

derive type:single value: HOST(myURLs) as: 'myHost'

Output: Generates the new myHost column containing the host values extracted from the myURLs column. 

derive type:single value: HOST(column_url)
