我是sql方面的新手，我正在尝试创建一个相当复杂的存储过程，用于在Visual Studio的Business Intelligence中使用sql reporting services创建的报表

我有一个主“Project”表，它通过使用链接表（我的存储过程中感兴趣的是“Status”、“Facility”和“Branch”）链接其他各种表。申请所做的是研究人员提交一个项目，并通过以下审批流程：

专业健康经理>分公司负责人>健康管理团队

为了简化此审批流程，另一名团队成员开发了一个自定义工作流解决方案，该解决方案利用了“WorkflowHistory”表。此表中的内容（除其他外）包括ProjectId、WorkflowStep和执行工作流步骤的日期，以及执行该步骤的人员发布的注释。我想在我的报告中包括以下内容：

我在报告中需要的信息如下：

“ProjectId”和“Title”来自“Project”表。“设施”、“分支机构”和“状态”从链接到“项目”的表中删除Received'需要为项目执行初始工作流步骤的日期。“结束”需要是为项目执行最终工作流步骤的日期。“注释”必须是留给最后一个工作流步骤的注释

因此，报告中每一行的数据来自以下位置：

  • “项目”中的一行
  • “分行”的一行
  • “状态”中的一行
  • 来自“Facility”的多行（在下面的运行尝试中，我仅返回子查询中的第一个Facility，但我希望所有分配给项目的Facility都以逗号分隔）
  • “WorkflowHistory”中的两行不同
用户传递以下参数以筛选报告：

  • 起始日期-获取特定日期后收到的所有报告（这将是“WorkflowHistory”中第一个工作流步骤的“ActionOn”）
  • 截止日期-获取特定日期之前收到的所有报告（这将是“WorkflowHistory”中最后一个工作流步骤的“ActionOn”）
  • 状态-筛选具有特定状态的项目
  • 分支-筛选指定给特定分支的项目

我已经尝试使用下面的存储过程来完成所有这一切。这是我的跑步尝试，我一直在努力。我仍然面临的问题包括：

  • 日期范围筛选不起作用
  • I只能返回子查询中的第一个工具 （以下是评论整个WHERE部分时仍然存在的问题）
  • 项目的最后一个工作流步骤可能是2到5之间的任何一个步骤，这取决于它是否被批准以及何时被拒绝。我需要弄清楚如何获得“结束”日期以及在这一步上留下的评论
  • 我在参数中传递“状态”。我需要弄清楚如何按一种状态或所有状态（实际上不是所有状态，但最后3种状态是“批准”、“拒绝”和“结束”）提交文件。分支机构也一样
编辑：现在是什么，5小时后，我已经更新了下面的存储过程。通过使用临时表变量，我已经解决了大多数问题
