      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

      当需要限制行数时：
      1. 12c以下版本必须使用ROWNUM语法
      2. 12c+版本推荐使用FETCH FIRST语法
      <note>
        版本适配：
          - Oracle 12c以下：必须使用 WHERE ROWNUM <= N
          - Oracle 12c+：推荐使用 FETCH FIRST N ROWS ONLY
      </note>
      <note>
        <strong>重要：ROWNUM必须放在正确的位置，避免语法错误</strong>
          1. <strong>单层查询</strong>：ROWNUM直接跟在WHERE子句后
             <template>SELECT ... FROM table WHERE conditions AND ROWNUM <= N</template>
          2. <strong>多层查询</strong>：ROWNUM只能放在最外层
             <template>
             SELECT ... FROM (
               SELECT ... FROM table WHERE conditions GROUP BY ...
             ) WHERE ROWNUM <= N  -- 正确：在最外层
             </template>
          3. <strong>禁止的错误写法</strong>：
             <error-example>
             SELECT ... FROM table 
             WHERE conditions 
             GROUP BY ...
             ORDER BY ...
             WHERE ROWNUM <= N  -- 错误：不能有多个WHERE
             </error-example>
          4. <strong>正确顺序</strong>：WHERE → GROUP BY → HAVING → ORDER BY → ROWNUM
          5. <strong>括号位置</strong>：从内层SELECT开始到内层结束都要括起来
             <correct>
             SELECT ... FROM (
               -- 内层完整查询（包含自己的SELECT、FROM、WHERE、GROUP BY、ORDER BY）
               SELECT columns FROM table WHERE conditions GROUP BY ... ORDER BY ...
             ) alias WHERE ROWNUM <= N
             </correct>
      </note>
    </rule>

        📌 以下示例严格遵循<Rules>中的 Oracle 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
