-- 1. 创建广场作品表
-- ============================================================

CREATE TABLE IF NOT EXISTS `plaza_work` (
  `id` BIGINT NOT NULL AUTO_INCREMENT COMMENT '主键ID',
  `work_no` VARCHAR(50) NOT NULL COMMENT '作品编号（唯一标识）',
  `user_id` BIGINT NOT NULL COMMENT '发布者用户ID',

) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci COMMENT='广场作品表';

-- ============================================================
-- 2. 创建点赞表
-- ============================================================

CREATE TABLE IF NOT EXISTS `plaza_work_like` (
  `id` BIGINT NOT NULL AUTO_INCREMENT COMMENT '主键ID',
  `work_id` BIGINT NOT NULL COMMENT '作品ID',
  `user_id` BIGINT NOT NULL COMMENT '点赞用户ID',

  KEY `idx_create_time` (`create_time`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci COMMENT='广场作品点赞表';

-- ============================================================
-- 3. 创建浏览记录表（可选，用于统计）
-- ============================================================

CREATE TABLE IF NOT EXISTS `plaza_work_view` (
  `id` BIGINT NOT NULL AUTO_INCREMENT COMMENT '主键ID',
  `work_id` BIGINT NOT NULL COMMENT '作品ID',
  `user_id` BIGINT DEFAULT NULL COMMENT '浏览用户ID（可为空，支持匿名浏览）',

  KEY `idx_view_time` (`view_time`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci COMMENT='广场作品浏览记录表';

-- ============================================================
-- 4. 插入示例数据（可选）
-- ============================================================

-- 假设用户ID 17563793187762127 发布了几个作品
-- INSERT INTO `plaza_work` (`work_no`, `user_id`, `task_no`, `task_type`, `model_name`, `prompt`, `result_url`, `title`, `tags`, `is_public`) VALUES
-- ('WORK-20251026-001', 17563793187762127, 'TASK-20251026183750127-8554', 'image_to_video', 'sc_sora2_img_landscape_15s_small', '根据参考图生成战场短视频', 'https://oss-1818ai-user-img.oss-cn-hangzhou.aliyuncs.com/result.mp4', '战场气氛短视频', '["视频","战争","特效"]', 1),
-- ('WORK-20251026-002', 17563793187762127, 'TASK-20251026120000000-0001', 'text_to_image', 'sc_soraimg_text_1x1', '一只可爱的橘猫在窗台晒太阳', 'https://oss-1818ai-user-img.oss-cn-hangzhou.aliyuncs.com/cat.png', '窗台上的橘猫', '["猫咪","温馨","治愈"]', 1);

-- ============================================================
-- 5. 添加索引优化查询性能
-- ============================================================

-- 复合索引：按任务类型和创建时间查询热门作品
CREATE INDEX `idx_type_like_time` ON `plaza_work`(`task_type`, `like_count` DESC, `create_time` DESC);

-- 复合索引：按状态和公开性查询
CREATE INDEX `idx_status_public_time` ON `plaza_work`(`status`, `is_public`, `create_time` DESC);

-- ============================================================
-- 6. 创建视图：热门作品
-- ============================================================

CREATE OR REPLACE VIEW `v_plaza_hot_works` AS
SELECT 
    pw.id,
    pw.work_no,
    pw.user_id,
    pw.task_type,
    pw.model_name,
    pw.title,
    pw.result_url,
    pw.like_count,
    pw.view_count,
    pw.create_time,
    u.nickname AS user_nickname,
    u.avatar_url AS user_avatar
FROM plaza_work pw
LEFT JOIN user u ON pw.user_id = u.id
WHERE pw.status = 'published' 
  AND pw.is_public = 1 
  AND pw.is_deleted = 0
ORDER BY pw.like_count DESC, pw.create_time DESC;

-- ============================================================
-- 7. 创建视图：最新作品
-- ============================================================

CREATE OR REPLACE VIEW `v_plaza_latest_works` AS
SELECT 
    pw.id,
    pw.work_no,
    pw.user_id,
    pw.task_type,
    pw.model_name,
    pw.title,
    pw.result_url,
    pw.like_count,
    pw.view_count,
    pw.create_time,
    u.nickname AS user_nickname,
    u.avatar_url AS user_avatar
FROM plaza_work pw
LEFT JOIN user u ON pw.user_id = u.id
WHERE pw.status = 'published' 
  AND pw.is_public = 1 
  AND pw.is_deleted = 0
ORDER BY pw.create_time DESC;

-- ============================================================
-- 验证表结构
-- ============================================================

SHOW CREATE TABLE plaza_work;
SHOW CREATE TABLE plaza_work_like;
SHOW CREATE TABLE plaza_work_view;
