+-- 素材列表布局重构迁移脚本
+-- Change ID: refactor-material-list-layout
+-- Date: 2025-12-28
+-- Description: 添加分组分类功能，支持混剪素材和数字人素材
+
+-- =====================================
+-- 1. 为tik_file_group表添加category字段
+-- =====================================
+
+ALTER TABLE tik_file_group
+ADD COLUMN category VARCHAR(20) NOT NULL DEFAULT 'MIX'
+COMMENT '分组分类: MIX(混剪素材), DIGITAL_HUMAN(数字人素材)'
+AFTER description;
+
+-- =====================================
+-- 2. 创建索引优化查询性能
+-- =====================================
+
+CREATE INDEX idx_file_group_user_category
+ON tik_file_group (user_id, category, deleted);
+
+-- =====================================
+-- 3. 为tik_user_file表的groupId字段添加注释
+-- =====================================
+
+ALTER TABLE tik_user_file
+MODIFY COLUMN group_id BIGINT NULL
+COMMENT '关联素材分组编号（关联tik_file_group.id）';
+
+-- =====================================
+-- 4. 迁移现有数据（将所有现有分组设置为MIX分类）
+-- =====================================
+
+UPDATE tik_file_group SET category = 'MIX' WHERE category IS NULL OR category = '';
+
+-- =====================================
+-- 5. 验证迁移结果
+-- =====================================
+
+SELECT category, COUNT(*) as group_count
+FROM tik_file_group
+WHERE deleted = FALSE
+GROUP BY category;
+
+-- =====================================
+-- 6. 创建统计视图（可选，用于性能优化）
+-- =====================================
+
+CREATE OR REPLACE VIEW v_file_group_stats AS
+SELECT
+    g.id,
+    g.user_id,
+    g.name,
+    g.category,
+    g.sort,
+    COUNT(f.id) as file_count
+FROM tik_file_group g
+LEFT JOIN tik_user_file f ON g.id = f.group_id AND f.deleted = FALSE
+WHERE g.deleted = FALSE
+GROUP BY g.id, g.user_id, g.name, g.category, g.sort;
+
+-- =====================================
+-- 7. 按分类统计文件数量
+-- =====================================
+
+SELECT
+    g.category,
+    COUNT(DISTINCT g.id) as group_count,
+    COUNT(f.id) as file_count
+FROM tik_file_group g
+LEFT JOIN tik_user_file f ON g.id = f.group_id AND f.deleted = FALSE
+WHERE g.deleted = FALSE
+GROUP BY g.category
+ORDER BY g.category;
