+-- Migration Script: Fix Database Field Name Inconsistencies
+-- Created: 2025-06-18
+-- Purpose: Standardize field names and remove duplicate columns
+
+-- =====================================================
+-- STEP 1: Create backup of affected data
+-- =====================================================
+
+-- Create backup table for sessions data
+CREATE TABLE IF NOT EXISTS sessions_backup_20250618 AS 
+SELECT * FROM sessions;
+
+-- =====================================================
+-- STEP 2: Create compatibility views (temporary)
+-- =====================================================
+
+-- Drop existing view if exists
+DROP VIEW IF EXISTS sessions_compat;
+
+-- Create compatibility view for smooth transition
+CREATE VIEW sessions_compat AS
+SELECT 
+    id,
+    license_id,
+    license_key,
+    session_id,
+    username,
+    computer_name,
+    hardware_id,
+    hardware_id as device_id,  -- Compatibility alias
+    ip_address,
+    user_agent,
+    app_version,
+    started_at,
+    started_at as login_time,  -- Compatibility alias
+    last_heartbeat,
+    last_heartbeat as last_activity,  -- Compatibility alias
+    ended_at,
+    ended_at as logout_time,  -- Compatibility alias
+    is_active,
+    is_active as active  -- Compatibility alias
+FROM sessions;
+
+-- =====================================================
+-- STEP 3: Update data in duplicate columns
+-- =====================================================
+
+-- Sync data from primary columns to alias columns (safety measure)
+UPDATE sessions SET 
+    login_time = COALESCE(login_time, started_at),
+    last_activity = COALESCE(last_activity, last_heartbeat),
+    logout_time = COALESCE(logout_time, ended_at),
+    active = COALESCE(active, is_active)
+WHERE login_time IS NULL 
+   OR last_activity IS NULL 
+   OR logout_time IS NULL 
+   OR active IS NULL;
+
+-- Sync data from alias columns to primary columns (if primary is null)
+UPDATE sessions SET 
+    started_at = COALESCE(started_at, login_time),
+    last_heartbeat = COALESCE(last_heartbeat, last_activity),
+    ended_at = COALESCE(ended_at, logout_time),
+    is_active = COALESCE(is_active, active)
+WHERE started_at IS NULL 
+   OR last_heartbeat IS NULL 
+   OR ended_at IS NULL 
+   OR is_active IS NULL;
+
+-- =====================================================
+-- STEP 4: Create function to check code dependencies
+-- =====================================================
+
+CREATE OR REPLACE FUNCTION check_field_usage()
+RETURNS TABLE (
+    query_count INTEGER,
+    field_name TEXT,
+    usage_type TEXT
+) AS $$
+BEGIN
+    -- Check for references to old field names
+    RETURN QUERY
+    SELECT 
+        COUNT(*)::INTEGER,
+        'device_id'::TEXT,
+        'Should use hardware_id'::TEXT
+    FROM pg_stat_statements
+    WHERE query ILIKE '%device_id%'
+    
+    UNION ALL
+    
+    SELECT 
+        COUNT(*)::INTEGER,
+        'active'::TEXT,
+        'Should use is_active'::TEXT
+    FROM pg_stat_statements
+    WHERE query ILIKE '%active%' 
+      AND query NOT ILIKE '%is_active%'
+    
+    UNION ALL
+    
+    SELECT 
+        COUNT(*)::INTEGER,
+        'login_time'::TEXT,
+        'Should use started_at'::TEXT
+    FROM pg_stat_statements
+    WHERE query ILIKE '%login_time%';
+END;
+$$ LANGUAGE plpgsql;
+
+-- =====================================================
+-- STEP 5: Migration queries for code updates
+-- =====================================================
+
+-- These queries help identify code that needs updating:
+
+-- Find sessions queries using old field names
+COMMENT ON VIEW sessions_compat IS 
+'Compatibility view for sessions table during field name migration.
+Old fields mapped:
+- device_id → hardware_id
+- active → is_active  
+- login_time → started_at
+- last_activity → last_heartbeat
+- logout_time → ended_at';
+
+-- =====================================================
+-- STEP 6: Final cleanup (run after code is updated)
+-- =====================================================
+
+-- DO NOT RUN THIS UNTIL ALL CODE IS UPDATED!
