Add database view consolidation and migrate legacy tables
- Drop 27 unused views, create 24 new purpose-built views - New views cover: equipment, PCs, printers, notifications, applications, knowledge base, USB history, subnets, maps, and reports/charts - Migration scripts for legacy network device tables (servers, cameras, switches, accesspoints, idfs) to unified machines table - Migration scripts for legacy tables (machineoverrides, dualpathassignments, networkinterfaces) - Update displaydevice.asp and displaylocationdevice.asp to use machines table - Fix deviceserver.asp type mismatch error with HTMLEncode - Hide Applications tab for equipment in displaymachine.asp 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

-- Migration: Drop Legacy Network Device Tables
|
||||
--
|
||||
-- This script removes the old network device tables (accesspoints, cameras,
|
||||
-- idfs, servers, switches) after migrating all data and dependencies to use
|
||||
-- the unified machines table.
|
||||
--
|
||||
-- IMPORTANT: Run this on DEV first and test thoroughly before production!
|
||||
--
|
||||
-- Prerequisites:
|
||||
-- - All network devices should already be in machines table with appropriate
|
||||
-- machinetypeid values (16=Access Point, 17=Camera, 18=IDF, 19=Switch, 20=Server)
|
||||
-- - displaydevice.asp and displaylocationdevice.asp should be updated to
|
||||
-- use machines table instead of legacy tables
|
||||
-- - networkdevices.asp already uses vw_network_devices (no changes needed)
|
||||
-- - deviceserver.asp already uses machines table (no changes needed)
