quot_rule: |
|
||
<rule>
|
||
必须对数据库名、表名、字段名、别名外层加反引号（`）。
|
||
<note>
|
||
1. 点号（.）不能包含在反引号内，必须写成 `database`.`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反引号
|
||
3. Doris 标识符默认不区分大小写，但建议统一使用反引号
|

||
limit_rule: |
|
||
<rule>
|
||
当需要限制行数时，必须使用标准的LIMIT语法
|
||
<note>
|
||
1. 标准写法：LIMIT [count]
|
||
2. 分页写法：LIMIT [count] OFFSET [start]
|
||
3. 支持 MySQL 兼容写法：LIMIT [offset], [count]

other_rule: |
|
||
<rule>必须为每个表生成别名（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：CONCAT(ROUND(x*100,2),'%')</rule>
|
||
<rule>避免与Doris关键字冲突（如`rank`/`partition`/`values`）</rule>
|
||
<rule>分区查询需使用PARTITION语句明确指定</rule>

📌 以下示例严格遵循<Rules>中的 Doris 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
