        ];
    }
    
    // 高级连接选项
    public function getAdvancedOptions() {
        return [
            '连接超时' => 'connect_timeout=10',
            '保持连接' => 'keepalive=1',
            '字符集' => 'charset=utf8',
            '时区设置' => 'timezone=Asia/Shanghai'
        ];
    }
}

// 实际连接示例
$connectionConfigs = [

        ]
    ]
];
?>

3.2 连接池与高可用配置

连接池管理类

<?php
class KingbaseConnectionPool {
    private $pool;
    private $config;
    private $maxSize;
    private $currentSize = 0;
    
    public function __construct($config, $maxSize = 20) {
        $this->config = $config;
        $this->maxSize = $maxSize;
        $this->pool = new SplQueue();
    }
    
    public function getConnection() {
        if (!$this->pool->isEmpty()) {
            return $this->pool->dequeue();
        }
        
        if ($this->currentSize < $this->maxSize) {
            $this->currentSize++;
            return $this->createConnection();
        }
        
        // 等待连接释放
        return $this->waitForConnection();
    }
    
    public function releaseConnection($connection) {
        if ($this->pool->count() < $this->maxSize) {
            $this->pool->enqueue($connection);
        } else {
            // 关闭超额连接
            $connection = null;
            $this->currentSize--;
        }
    }
    
    private function createConnection() {
        try {
            return new PDO(
                $this->config['dsn'],
                $this->config['username'],
                $this->config['password'],
                $this->config['options']
            );
        } catch (PDOException $e) {
            throw new Exception("连接创建失败: " . $e->getMessage());
        }
    }
}

// 使用示例
$pool = new KingbaseConnectionPool($connectionConfigs['production']);
$dbh = $pool->getConnection();
try {
    // 执行数据库操作
    $stmt = $dbh->query("SELECT * FROM users");
    $results = $stmt->fetchAll(PDO::FETCH_ASSOC);

    private $pdo;
    
    public function __construct($pdo) {
        $this->pdo = $pdo;
    }
    
    // 创建数据
    public function createUser($userData) {
        $sql = "INSERT INTO users (username, email, created_at) VALUES (?, ?, NOW())";
        $stmt = $this->pdo->prepare($sql);
        
        return $stmt->execute([
            $userData['username'],
            $userData['email']
        ]);

        $stmt = $this->pdo->prepare($sql);
        $stmt->execute([$userId]);
        
        return $stmt->fetch(PDO::FETCH_ASSOC);
    }
    
    // 更新数据
    public function updateUser($userId, $updateData) {
        $sql = "UPDATE users SET username = ?, email = ? WHERE id = ?";
        $stmt = $this->pdo->prepare($sql);
        
        return $stmt->execute([
            $updateData['username'],
            $updateData['email'],
            $userId
        ]);
    }
    
    // 删除数据（软删除）
    public function deleteUser($userId) {
        $sql = "UPDATE users SET status = 'deleted', deleted_at = NOW() WHERE id = ?";
        $stmt = $this->pdo->prepare($sql);
        
        return $stmt->execute([$userId]);
    }
    
    // 批量插入
    public function batchInsertUsers($users) {

            $values[] = $user['username'];
            $values[] = $user['email'];
        }
        
        $sql .= implode(',', $placeholders);
        $stmt = $this->pdo->prepare($sql);
        
        return $stmt->execute($values);
    }
}
?>

4.2 高级查询与性能优化

查询优化技巧

<?php
class KingbaseQueryOptimizer {
    private $pdo;
    
    public function __construct($pdo) {
        $this->pdo = $pdo;
    }
    
    // 分页查询优化
    public function getUsersWithPagination($page = 1, $pageSize = 20) {
        $offset = ($page - 1) * $pageSize;
        
        // 使用游标分页提高性能
        $sql = "SELECT * FROM users 
                WHERE id > ? AND status = 'active' 
                ORDER BY id 
                LIMIT ?";
        
        $stmt = $this->pdo->prepare($sql);
        $stmt->bindValue(1, $this->getLastPageMaxId($page), PDO::PARAM_INT);
        $stmt->bindValue(2, $pageSize, PDO::PARAM_INT);
        $stmt->execute();
        
        return $stmt->fetchAll(PDO::FETCH_ASSOC);
    }
    
    // 联合查询优化
    public function getUserWithProfile($userId) {
        $sql = "SELECT u.*, p.* 
                FROM users u 
                LEFT JOIN user_profiles p ON u.id = p.user_id 
                WHERE u.id = ?";
        
        $stmt = $this->pdo->prepare($sql);
        $stmt->execute([$userId]);
        
        return $stmt->fetch(PDO::FETCH_ASSOC);
    }
    
    // 使用EXPLAIN分析查询性能
    public function explainQuery($sql, $params = []) {
        $explainSql = "EXPLAIN (ANALYZE, BUFFERS) " . $sql;
        $stmt = $this->pdo->prepare($explainSql);
        $stmt->execute($params);
        
        return $stmt->fetchAll(PDO::FETCH_ASSOC);
    }
}
?>

    private $pdo;
    
    public function __construct($pdo) {
        $this->pdo = $pdo;
    }
    
    // 参数化查询示例
    public function safeQuery($userId, $searchTerm) {
        // 不安全的方式（绝对禁止！）
        // $sql = "SELECT * FROM users WHERE id = $userId AND name LIKE '%$searchTerm%'";
        
        // 安全的方式：参数化查询
        $sql = "SELECT * FROM users WHERE id = ? AND name LIKE ?";
        $stmt = $this->pdo->prepare($sql);
        
        // 正确绑定参数
        $stmt->bindValue(1, $userId, PDO::PARAM_INT);
        $stmt->bindValue(2, "%$searchTerm%", PDO::PARAM_STR);
        
        $stmt->execute();

    private $writePdo;
    private $readPdos = [];
    private $currentReadIndex = 0;
    
    public function __construct($writeConfig, $readConfigs) {
        // 写连接
        $this->writePdo = new PDO(
            $writeConfig['dsn'],
            $writeConfig['username'],
            $writeConfig['password'],
            $writeConfig['options']
        );
        
        // 读连接池
        foreach ($readConfigs as $config) {

        if ($isWrite) {
            return $this->writePdo;
        }
        
        // 轮询选择读库
        $pdo = $this->readPdos[$this->currentReadIndex];
        $this->currentReadIndex = ($this->currentReadIndex + 1) % count($this->readPdos);
        
        return $pdo;
    }
    
    public function executeQuery($sql, $params = [], $isWrite = false) {

    }
    
    // 数据库性能指标
    public function getPerformanceMetrics() {
        $metrics = [];
        
        // 连接数监控
        $metrics['connections'] = $this->pdo->query(
            "SELECT count(*) FROM sys_stat_activity"
        )->fetchColumn();
        
        // 缓存命中率
        $metrics['cache_hit_ratio'] = $this->pdo->query(
            "SELECT round(blks_hit*100/(blks_hit+blks_read), 2) 
             FROM sys_stat_database WHERE datname = current_database()"
        )->fetchColumn();
        
        // 锁等待监控
        $metrics['lock_wait'] = $this->pdo->query(
            "SELECT count(*) FROM sys_locks WHERE granted = false"
        )->fetchColumn();
        
        return $metrics;
    }
    
    // 慢查询日志
    public function getSlowQueries($threshold = 1000) {
        $sql = "SELECT query, duration 
                FROM sys_stat_statements 
                WHERE duration > ? 
                ORDER BY duration DESC 
                LIMIT 10";
        
        $stmt = $this->pdo->prepare($sql);

        try {
            $this->pdo->beginTransaction();
            
            // 使用SELECT FOR UPDATE悲观锁
            $sql = "SELECT stock FROM products WHERE id = ? FOR UPDATE";
            $stmt = $this->pdo->prepare($sql);
            $stmt->execute([$productId]);
            $product = $stmt->fetch(PDO::FETCH_ASSOC);
            
            if ($product['stock'] <= 0) {
                $this->pdo->rollBack();
                return false;
            }
            
            // 扣减库存
            $updateSql = "UPDATE products SET stock = stock - 1 WHERE id = ?";
            $updateStmt = $this->pdo->prepare($updateSql);
            $updateStmt->execute([$productId]);
            
            // 创建订单
            $orderSql = "INSERT INTO orders (user_id, product_id, status) VALUES (?, ?, 'created')";
            $orderStmt = $this->pdo->prepare($orderSql);
            $orderStmt->execute([$userId, $productId]);
            
            $this->pdo->commit();
            return true;
            
        } catch (Exception $e) {
            $this->pdo->rollBack();
            error_log("秒杀失败: " . $e->getMessage());
            return false;
        }
    }
