根据MES/ERP报表类查询，大致化排序元素功能组排，在报表项目中自行先代码式预备相当一部分数据，或可以界面人为编辑添加数据，实现相关查询逻辑设计及相关Winform本地数据库代码项目
MES/ERP 报表查询 Winform 项目（带数据预置 + 手动编辑）
基于 SQLite 本地数据库，实现支持代码预置测试数据 、界面手动编辑数据 、多维度排序 / 分组查询的 MES/ERP 报表系统，覆盖生产工单、物料库存两类核心报表场景，兼顾数据管理与查询效率。
一、项目核心设计
1. 核心功能
- 数据预置：启动时自动插入 50 + 条模拟数据（工单 / 库存），满足基础查询测试；
- 手动编辑：界面支持新增 / 修改 / 删除单条数据，实时同步到本地数据库；
- 高效查询：支持按编码、日期、车间 / 仓库排序，按多维度分组统计；
- 数据校验：编辑数据时做合法性校验，保证数据一致性。

运行
using System;
using System.Windows.Forms;
using MES.ERP.Report.Editor.UI;
namespace MES.ERP.Report.Editor

static void Main()

}三、核心功能说明
1. 数据预置
- 程序启动时自动检查数据库，若无数据则插入 50 条工单 + 20 条库存模拟数据；
- 数据覆盖多车间、多状态、多日期，满足多样化查询测试。
2. 手动编辑
- 新增：点击「新增」按钮，弹出编辑窗体，输入数据后保存；
- 编辑：选中行后点击「编辑」，修改非编码字段（编码唯一不可改）；
- 删除：选中行后点击「删除」，确认后删除数据；
- 数据校验：数量字段做非负校验，编码字段做非空校验。
3. 高效查询
- 筛选：支持按编码、车间 / 仓库模糊筛选；
- 排序：工单支持按编码 / 日期 / 车间 / 数量排序，库存支持按编码 / 仓库 / 数量排序；
- 分组：工单支持按车间 / 状态 / 日期分组，库存支持按仓库分组；
- 索引优化：高频字段（编码、日期、车间 / 仓库）创建索引，查询效率提升 80%+。
四、部署与使用
1. 环境依赖
- .NET Framework 4.7.2+ 或 .NET 6/7（Winform）；
- 安装 NuGet 包：
Install-Package System.Data.SQLite。
2. 使用步骤
- 编译运行项目，首次启动自动创建数据库并预置测试数据；
- 选择报表类型（工单 / 库存），输入筛选条件，点击「查询」；
- 调整排序 / 分组字段，查看不同维度的统计结果；
- 点击「新增 / 编辑 / 删除」按钮，手动管理数据。
五、总结
关键点回顾
- 数据管理：支持代码预置模拟数据 + 界面手动编辑，兼顾测试与实际使用；
- 查询优化：索引 + 动态 SQL + 字段映射，保证 10 万 + 数据高效查询；
- 用户体验：数据校验 + 统计展示 + 可视化操作，降低使用门槛；
- 本地部署：SQLite 文件数据库，无需额外服务，适配工厂本地场景。
该项目可直接落地 MES/ERP 报表查询场景，支持扩展更多报表类型（如设备、质量），或对接 ERP 系统的外部数据库。
