出于示例目的，我在查询中仅选择了两个修复引用。输出显示每个修复引用的多个记录。对于每次修复，可以有多个序列，每个序列都有一个交易人员（如下所示）：
╔══════════════════╦══════════════╦══════════════╦════════════╦═══════════════╗

客户端只需要根据修复参考显示一条记录（示例如下所示） - 我可以使用Job_Sequence = 1执行此操作。如果每个Trade有多个Multi Trade类型，我遇到的问题是让Trade显示Repair Reference。这就是我所挣扎的。是否可以查看所有Trades per Repair Reference，如果有多种类型，则显示文本多重交易，否则只有一个Trade/Trade Code Repair Reference然后只使用交易：
╔══════════════════╦══════════════╦══════════════╦════════════╦══════════════╗
║ Repair Reference ║ Tenant Name ║ Job Sequence ║ Trade Code ║ Trade ║
╠══════════════════╬══════════════╬══════════════╬════════════╬══════════════╣
║ 57257795 ║ MISS L SMITH ║ 1 ║ 41 ║ Multi Trade ║
║ 57342819 ║ MISS A GREEN ║ 1 ║ 40 ║ Multi Trade ║

这是我目前获得的SQL：

我尝试使用row_number（）
import {BrandsService} from './brands.service';
export default [BrandsService];
export {BrandsService}
答案 1 :(得分：0)
这可能有用 - 基本上每行我都会询问是否存在更高的工作顺序：

我还评论了一个无用的条件。
