-- Schema Fix Script for Server Database
-- This script migrates auction_id and lot_id from BIGINT to TEXT to match scraper format
-- The scraper uses TEXT IDs like "A7-40063-2" but DatabaseService.java was creating BIGINT columns

-- Step 1: Backup existing data
CREATE TABLE IF NOT EXISTS auctions_backup AS SELECT * FROM auctions;
CREATE TABLE IF NOT EXISTS lots_backup AS SELECT * FROM lots;
CREATE TABLE IF NOT EXISTS images_backup AS SELECT * FROM images;

-- Step 2: Drop existing tables (CASCADE would drop foreign keys)
DROP TABLE IF EXISTS images;
DROP TABLE IF EXISTS lots;
DROP TABLE IF EXISTS auctions;

-- Step 3: Recreate auctions table with TEXT primary key (matching scraper format)
CREATE TABLE auctions (
    auction_id TEXT PRIMARY KEY,
    title TEXT NOT NULL,
    location TEXT,
    city TEXT,
    country TEXT,
    url TEXT NOT NULL UNIQUE,
    type TEXT,
    lot_count INTEGER DEFAULT 0,
    closing_time TEXT,
    discovered_at INTEGER
);

-- Step 4: Recreate lots table with TEXT primary key (matching scraper format)
CREATE TABLE lots (
    lot_id TEXT PRIMARY KEY,
    sale_id TEXT,
    auction_id TEXT,
    title TEXT,
    description TEXT,
    manufacturer TEXT,
    type TEXT,
    year INTEGER,
    category TEXT,
    current_bid REAL,
    currency TEXT DEFAULT 'EUR',
    url TEXT UNIQUE,
    closing_time TEXT,
    closing_notified INTEGER DEFAULT 0,
    starting_bid REAL,
    minimum_bid REAL,
    status TEXT,
    brand TEXT,
    model TEXT,
    attributes_json TEXT,
    first_bid_time TEXT,
    last_bid_time TEXT,
    bid_velocity REAL,
    bid_increment REAL,
    year_manufactured INTEGER,
    condition_score REAL,
    condition_description TEXT,
    serial_number TEXT,
    damage_description TEXT,
    followers_count INTEGER DEFAULT 0,
    estimated_min_price REAL,
    estimated_max_price REAL,
    lot_condition TEXT,
    appearance TEXT,
    estimated_min REAL,
    estimated_max REAL,
    next_bid_step_cents INTEGER,
    condition TEXT,
    category_path TEXT,
    city_location TEXT,
    country_code TEXT,
    bidding_status TEXT,
    packaging TEXT,
    quantity INTEGER,
    vat REAL,
    buyer_premium_percentage REAL,
    remarks TEXT,
    reserve_price REAL,
    reserve_met INTEGER,
    view_count INTEGER,
    bid_count INTEGER,
    viewing_time TEXT,
    pickup_date TEXT,
    location TEXT,
    scraped_at TEXT,
    FOREIGN KEY (auction_id) REFERENCES auctions(auction_id),
    FOREIGN KEY (sale_id) REFERENCES auctions(auction_id)
);

-- Step 5: Recreate images table
CREATE TABLE images (
    id INTEGER PRIMARY KEY AUTOINCREMENT,
    lot_id TEXT,
    url TEXT,
    local_path TEXT,
    labels TEXT,
    processed_at INTEGER,
    downloaded INTEGER DEFAULT 0,
    FOREIGN KEY (lot_id) REFERENCES lots(lot_id)
);

-- Step 6: Create bid_history table if it doesn't exist
CREATE TABLE IF NOT EXISTS bid_history (
    id INTEGER PRIMARY KEY AUTOINCREMENT,
    lot_id TEXT,
    bid_amount REAL,
    bid_time TEXT,
    is_autobid INTEGER DEFAULT 0,
    bidder_id TEXT,
    bidder_number INTEGER,
    FOREIGN KEY (lot_id) REFERENCES lots(lot_id)
);

-- Step 7: Restore data from backup (converting BIGINT to TEXT if needed)
INSERT OR IGNORE INTO auctions SELECT * FROM auctions_backup;
INSERT OR IGNORE INTO lots SELECT * FROM lots_backup;
INSERT OR IGNORE INTO images SELECT * FROM images_backup;

-- Step 8: Create indexes for performance
CREATE INDEX IF NOT EXISTS idx_auctions_country ON auctions(country);
CREATE INDEX IF NOT EXISTS idx_lots_sale_id ON lots(sale_id);
CREATE INDEX IF NOT EXISTS idx_lots_auction_id ON lots(auction_id);
CREATE INDEX IF NOT EXISTS idx_images_lot_id ON images(lot_id);

-- Step 9: Clean up backup tables (optional - comment out if you want to keep backups)
-- DROP TABLE auctions_backup;
-- DROP TABLE lots_backup;
-- DROP TABLE images_backup;
