The following SQL pattern can be used to tranform a RefCursor query resultset into data in HTML table format by utilizing the XSLT functionality. The query can handle NULL in the data columns. The SQL input string should be based on the following format:

The following SQL pattern can be used to convert a RefCursor query result set into a CSV format. This query can handle NULL in the data columns. The SQL input string should be based on the following format:
SELECT Col AS name_x, Function() AS name_y, Analytical_function( ) AS name_z FROM (more...)
The following SQL pattern can be used to tranform the CSV file into a HTML table by utilizing the XQUERY functionality.
create or replace directory tmp as '/tmp';

First, every result of a function or query for which result cache is enabled has its own dependencies.
Second, all dependencies are tracked while the function/query is being executed.
Third, the PL/SQL function result cache and the SQL result cache internals are the same.
Fourth, if you have a function within a query, for which result cache hint is used, the dependencies for the query result will include the dependencies on the objects accessed by the function.
