template:
  quot_rule: |
    <rule>
      必须对索引名（表名）、字段名、别名外层加双引号（"）。
      <note>
        1. 通配符索引需整体加引号：`"logs-*"`
        2. 嵌套字段用点号连接：`"user.name"`
        3. 时间字段必须显式转换：`CAST("@timestamp" AS TIMESTAMP)`
      </note>
    </rule>

  limit_rule: |
    <rule>
      当需要限制行数时，必须使用标准的LIMIT语法
      <note>
        1. 首选：`LIMIT [count]`
        2. 分页：`LIMIT [count] OFFSET [start]`
        3. 禁止使用Elasticsearch原生`size/from`参数
      </note>
    </rule>

  other_rule: |
    <rule>必须为每个索引生成别名（不加AS）</rule>
    <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：`ROUND(x*100,2) || '%'`</rule>
    <rule>避免与Elasticsearch关键字冲突（如`score`/`type`）</rule>

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