+
+-- 执行主要的数据库架构创建
+-- 这里会包含 schema.sql 的内容
+
+-- 1. 文件表 - 存储文件元数据
+CREATE TABLE IF NOT EXISTS files (
+    id TEXT PRIMARY KEY,
+    value TEXT,
+    metadata TEXT NOT NULL,
+    file_name TEXT,
+    file_type TEXT,
+    file_size TEXT,
+    upload_ip TEXT,
+    upload_address TEXT,
+    list_type TEXT,
+    timestamp INTEGER,
+    label TEXT,
+    directory TEXT,
+    channel TEXT,
+    channel_name TEXT,
+    tg_file_id TEXT,
+    tg_chat_id TEXT,
+    tg_bot_token TEXT,
+    is_chunked BOOLEAN DEFAULT FALSE,
+    created_at DATETIME DEFAULT CURRENT_TIMESTAMP,
+    updated_at DATETIME DEFAULT CURRENT_TIMESTAMP
+);
+
+-- 2. 系统配置表
+CREATE TABLE IF NOT EXISTS settings (
+    key TEXT PRIMARY KEY,
+    value TEXT NOT NULL,
+    category TEXT,
+    description TEXT,
+    created_at DATETIME DEFAULT CURRENT_TIMESTAMP,
+    updated_at DATETIME DEFAULT CURRENT_TIMESTAMP
+);
+
+-- 3. 索引操作表
+CREATE TABLE IF NOT EXISTS index_operations (
+    id TEXT PRIMARY KEY,
+    type TEXT NOT NULL,
+    timestamp INTEGER NOT NULL,
+    data TEXT NOT NULL,
+    processed BOOLEAN DEFAULT FALSE,
+    created_at DATETIME DEFAULT CURRENT_TIMESTAMP
+);
+
+-- 4. 索引元数据表
+CREATE TABLE IF NOT EXISTS index_metadata (
+    key TEXT PRIMARY KEY,
+    last_updated INTEGER,
+    total_count INTEGER DEFAULT 0,
+    last_operation_id TEXT,
+    chunk_count INTEGER DEFAULT 0,
+    chunk_size INTEGER DEFAULT 0,
+    created_at DATETIME DEFAULT CURRENT_TIMESTAMP,
+    updated_at DATETIME DEFAULT CURRENT_TIMESTAMP
+);
+
+-- 5. 其他数据表
+CREATE TABLE IF NOT EXISTS other_data (
+    key TEXT PRIMARY KEY,
+    value TEXT NOT NULL,
+    type TEXT,
+    description TEXT,
+    created_at DATETIME DEFAULT CURRENT_TIMESTAMP,
+    updated_at DATETIME DEFAULT CURRENT_TIMESTAMP
+);
+
+-- 创建索引
+CREATE INDEX IF NOT EXISTS idx_files_timestamp ON files(timestamp DESC);

+CREATE INDEX IF NOT EXISTS idx_index_operations_type ON index_operations(type);
+
+CREATE INDEX IF NOT EXISTS idx_other_data_type ON other_data(type);
+
+-- 创建触发器
+CREATE TRIGGER IF NOT EXISTS update_files_updated_at 
+    AFTER UPDATE ON files
+    BEGIN
+        UPDATE files SET updated_at = CURRENT_TIMESTAMP WHERE id = NEW.id;
+    END;
+
+CREATE TRIGGER IF NOT EXISTS update_settings_updated_at 
+    AFTER UPDATE ON settings
+    BEGIN
+        UPDATE settings SET updated_at = CURRENT_TIMESTAMP WHERE key = NEW.key;
+    END;
+
+CREATE TRIGGER IF NOT EXISTS update_index_metadata_updated_at 
+    AFTER UPDATE ON index_metadata
+    BEGIN
+        UPDATE index_metadata SET updated_at = CURRENT_TIMESTAMP WHERE key = NEW.key;
+    END;
+
+CREATE TRIGGER IF NOT EXISTS update_other_data_updated_at 
+    AFTER UPDATE ON other_data
+    BEGIN
+        UPDATE other_data SET updated_at = CURRENT_TIMESTAMP WHERE key = NEW.key;
+    END;
+
+-- 插入初始的索引元数据
+INSERT OR REPLACE INTO index_metadata (key, last_updated, total_count, last_operation_id)
+VALUES ('main_index', 0, 0, NULL);
+
+-- 初始化完成
+-- 数据库已准备就绪，可以开始迁移数据
