【帆软FineReport】 聚焦企业级数据可视化与报表开发。本专栏深入解析 FineReport 与 FineBI 核心技巧，涵盖复杂报表设计、参数联动、填报功能及大屏可视化（决策平台）。
拒绝空谈理论，专注解决数据孤岛、报表自动化及性能优化等企业痛点。我将分享多年沉淀的帆软开发套路与 SQL 优化经验，助你快速从"取数工具人"进阶为"数据架构师"。关注我，用报表驱动业务增长！
一、需求描述
分类汇总报表，计算复卷率。
二、技术要点
${cboMachineId}：输入框传参
COALESCE：SQL 中用于处理 NULL 值 的核心函数，它返回参数列表中第一个非空（NOT NULL）的值。如果所有参数都为 NULL，则返回 NULL。
三、解决方案
数据集脚本：
sql
WITH
-- 淋膜产出

select tax0009.C_GROUP_LINE,top3230.*
