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:
| D code |
|---|
derive type:single value: HOST('http://www.example.com' ) as: 'myHost' |
Output: Generates a column containing the value www.example.com.
Column reference example:
| D code |
|---|
derive type:single value: HOST(myURLs) as: 'myHost' |
Output: Generates the new myHost column containing the host values extracted from the myURLs column.
| D code |
|---|
derive type:single value: HOST(column_url) |
