  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
        3. Oracle 对象名默认大写，如需小写必须加双引号

        ⚠️ 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
