Export one or more queries as csv data within a zip file:

DECLARE
  l_file plex.file;
BEGIN

  --fill the queries array
  plex.add_query(
    p_query       => 'select * from user_tables',
    p_file_name   => 'user_tables'

  plex.add_query(
    p_query       => 'select * from user_tab_columns',
    p_file_name   => 'user_tab_columns',
    p_max_rows    => 10000
  );

  -- get the zip file
  l_file.file_name := 'user-tables';
  plex.queries_to_csv(p_file => l_file);

  -- do something with the file...

  -- free the temp space, which was created by plex for the blob_content column
  dbms_lob.freetemporary(l_file.blob_content);

END;
