I believe you can do at least one of these possibilities:

- SELECT <pattern> INTO <sth> FROM <table> to move sensitive data
  from some private table to publicly available tables used eg. for
  direct contents rendering,

- call WebDB output procedures to produce output (you can use full
  PL/SQL language syntax, including loops, declarations etc).
