Detailed Description

This class implements a view onto a complete database. The view names correspond to the names of all existing tables. Optionally, the views can be restricted to subsets of the tables. All constructed views are standard views.

Constructor & Destructor Documentation

viewdbase::viewdbase (    )  [inline]

standard constructor Definition at line 203 of file vdbl_viewdbase.h.

viewdbase::viewdbase (  const database &    db, const userid &    uid, const context &    c )  [inline]

constructor which builds a view to the database from db -- the database c -- the evaluation context for all views Definition at line 210 of file vdbl_viewdbase.h.

template<template< class _C, class _A > class _SqCtr, class _Al> viewdbase::viewdbase (  const database &    db, const userid &    uid, const context &    c, const _SqCtr< std::pair< tableid, rowid >, _Al > &    __an )  [inline]

constructor which builds a view to the database from db -- the database c -- the evaluation context for all views uid -- the user id of the user who owns the view The fourth argument is any sequential container of table,row pairs to which the view shall be restricted.
