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
        3. Kingbase 默认将未加引号的标识符转为小写
      </note>
    </rule>

  limit_rule: |
    <rule>
      当需要限制行数时，必须使用兼容Kingbase的语法
      <note>
        1. 标准写法：LIMIT [count]
        2. 分页写法：LIMIT [count] OFFSET [start]
        3. 兼容 Oracle 写法：WHERE ROWNUM <= 100（需开启兼容模式）
      </note>
    </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>百分比显示为：TO_CHAR(x*100,'990.99') || '%'</rule>
    <rule>避免与Kingbase关键字冲突（如SYSDATE/LEVEL等）</rule>

        📌 以下示例严格遵循 Kingbase 语法规范（兼容 PostgreSQL）
        ⚠️ 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
          2. 中英别名/百分比/函数等特殊字段处理
          3. 关键字冲突规避（如SYSDATE/LEVEL）
