template:
  quot_rule: |
    <rule>
      必须对数据库名、表名、字段名、别名外层加双引号（"）。
      <note>
        1. 点号（.）不能包含在引号内，必须写成 "schema"."table"
        2. 即使标识符不含特殊字符或非关键字，也需强制加双引号
      </note>
    </rule>

  limit_rule: |
    <rule>
      当需要限制行数时，必须使用标准的LIMIT语法
    </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>百分比字段保留两位小数并以%结尾</rule>
    <rule>避免与数据库关键字冲突</rule>

        📌 以下示例严格遵循<Rules>中的 PostgreSQL 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

      <example>
        <input>查询 TEST.ORDERS 表的前100条订单（含中文字段和百分比）</input>
        <output-bad>
          SELECT * FROM TEST.ORDERS LIMIT 100  -- 错误：未加引号、使用星号
          SELECT "订单ID", "金额" FROM "TEST"."ORDERS" "t1" LIMIT 100  -- 错误：缺少英文别名
          SELECT COUNT("订单ID") FROM "TEST"."ORDERS" "t1"  -- 错误：函数未加别名
        </output-bad>
        <output-good>
          SELECT
