NEW QUESTION 566
How is unstructured data retrieved from data storage?

SQL functions like the GET command can be used to copy the unstructured data to a location on the client.

SQL functions can be used to create different types of URLs pointing to the unstructured data. These URLs can be used to download the data to a client.

SQL functions can be used to retrieve the data from the query results cache. When the query results are output to a client, the unstructured data will be output to the client as files.

SQL functions can call on different web extensions designed to display different types of files as a web page. The web extensions will allow the files to be downloaded to the client.
