template:
  quot_rule: |
    <rule>
      必须对数据库名、表名、字段名、别名外层加方括号（[]）。
      <note>
        1. 点号（.）不能包含在方括号内，必须写成 [schema].[table]
        2. 当标识符为关键字、含特殊字符或需保留大小写时必须加方括号
        3. SQL Server 标识符默认不区分大小写
      </note>
    </rule>

  limit_rule: |
    <rule>
      当需要限制行数时，必须使用 Microsoft SQL Server 的SQL语法：
      <note>
        1. 标准写法：TOP [count]
        2. 分页写法：OFFSET [start] ROWS FETCH NEXT [count] ROWS ONLY
        3. 禁止使用 MySQL 的 LIMIT 语法
      </note>
    </rule>

  other_rule: |
    <rule>必须为每个表生成别名（不加AS）</rule>
    {multi_table_condition}
    <rule>禁止使用星号(*)，必须明确字段名</rule>
    <rule>中文/特殊字符字段需保留原名并添加英文别名</rule>
    <rule>函数字段必须加别名</rule>
    <rule>百分比显示为：CONVERT(VARCHAR, ROUND(x*100,2)) + '%'</rule>
    <rule>避免与SQL Server关键字冲突（如[user]/[order]/[desc]）</rule>

        📌 以下示例严格遵循<Rules>中的 Microsoft SQL Server 规范，展示符合要求的 SQL 写法与典型错误案例。
        ⚠️ 注意：示例中的表名、字段名均为演示虚构，实际使用时需替换为用户提供的真实标识符。
        🔍 重点观察：
          1. 双引号包裹所有数据库对象的规范用法
          2. 中英别名/百分比/函数等特殊字段的处理
          3. 关键字冲突的规避方式
      </intro>
      <example>
        <input>查询 Sales.Orders 表的前100条订单（含中文字段和百分比）</input>
        <output-bad>
          SELECT * FROM Sales.Orders  -- 错误：使用星号
          SELECT [订单ID], [金额] FROM [Sales].[Orders] [o]  -- 错误：缺少英文别名
          SELECT COUNT([订单ID]) FROM [Sales].[Orders] [o]  -- 错误：函数未加别名
        </output-bad>
        <output-good>
          SELECT TOP 100
            [o].[订单ID] AS [order_id],
            [o].[金额] AS [amount],
            COUNT([o].[订单ID]) AS [total_orders],
            CONVERT(VARCHAR, ROUND([o].[折扣率] * 100, 2)) + '%' AS [discount_percent]
          FROM [Sales].[Orders] [o]
        </output-good>
      </example>

      <example>
        <input>统计用户表 dbo.Users（含关键字字段user）的活跃占比</input>
        <output-bad>
          SELECT user, status FROM dbo.Users  -- 错误：未处理关键字
          SELECT [user], ROUND(active_ratio*100) FROM [dbo].[Users]  -- 错误：百分比格式错误
        </output-bad>
        <output-good>
          SELECT 
            [u].[user] AS [user_name],

          ORDER BY [u].[create_date]
