帮助向我的 sql 过程结果添加一个字段

Question

我有下面的 SQL 过程，我正在尝试将 SRS 开始日期字段添加到下面的过程的结果集中。我想为 SRS_StartDate 添加一个字段。该字段应定义为：coalesce(projectMilestone.startDate,releaseschedual.startDate) as SRS_StartDate - 但仅适用于 CID=37，因为这是 SRS 的 cid

我在下面附上我的示例 sql 代码我当前的进程和还有表结构和数据的文件。

您可以使用这些项目 ID 进行测试，因为 Excel 文件有数据支持它们。

exec rainbows '66,97,25'   --testing
