+# Xinhan 数据表结构说明
+
+本文档提供针对 xinhan 表的 SQL 创建语句与示例查询。注意：以下 SQL 仅用于创建结构；本任务仅生成 MD 文档，不执行 SQL。
+
+## 数据字段与含义
+- recipient: 收件人，为文本类型，必填
+- content: 内容物，文本型，可包含多行描述
+- sent_date: 寄出日期，时间戳（timestamptz/ TIMESTAMP），必填
+- destination: 寄达地，文本
+- arrival_date: 寄达日期，时间戳
+
+## 建表 SQL（PostgreSQL，Supabase/ Postgres 兼容）
+```sql
+CREATE TABLE xinhan (
+  id SERIAL PRIMARY KEY,
+  recipient TEXT NOT NULL,
+  content TEXT,
+  sent_date TIMESTAMP WITHOUT TIME ZONE NOT NULL,
+  destination TEXT,
+  arrival_date TIMESTAMP WITHOUT TIME ZONE
+);
+
+-- 索引，提升按收件人、寄出日期/寄达日期的查询性能
+CREATE INDEX IF NOT EXISTS idx_xinhan_recipient ON xinhan (recipient);
+CREATE INDEX IF NOT EXISTS idx_xinhan_sent_date ON xinhan (sent_date);
+CREATE INDEX IF NOT EXISTS idx_xinhan_arrival_date ON xinhan (arrival_date);
+```
+
+## 示例查询
+```sql
+-- 查询某个收件人相关信函的简单示例
+SELECT * FROM xinhan
+WHERE recipient ILIKE '%张三%'
+ORDER BY sent_date DESC
+LIMIT 100;
+
+-- 根据日期范围查询示例
+SELECT * FROM xinhan
+WHERE sent_date BETWEEN '2024-01-01' AND '2026-12-31'
+ORDER BY sent_date DESC;
+```
+
+> 说明：此文件仅用于记录数据库结构与查询示例，实际部署请在你的数据库实例中执行上述 SQL。
