限制 SSRS SQL 查询中的结果
Limiting results in SSRS SQL query
我正在尝试使用 SSRS 在我们的票务系统上生成报告。我正在从 "incident body" table 和 "incident details" table 中引入字段。我正在寻找的是工单是否已通过 SLA 以响应客户。
我正在通过两种方式检查通过 SLA 的票证：
1) 工单已过 SLA 日期，没有与预定类型匹配的详细记录
2) 工单有匹配预定类型的详细记录，但它在 SLA 日期之后
我能够构建下面的 CTE 部分，但我正在努力解决如何将结果减少到最旧的匹配 row/record。一张票应该只在报告中出现一次。
例如：
Johnny Blogs 在 2016 年 1 月 1 日使用 CONTACTED_TM 记录类型更新了工单。 SLA 是 2015 年 12 月 31 日。第二天 (1/2/2016) 他还使用 EMAILOUT 记录类型向 TM 发送电子邮件。 CTE return 都是这两个 rows/records。我只想要第一个结果。
我的查询代码如下。我曾尝试在 CTE 中使用 SELECT TOP 1，但它只会导致 return 没有结果。
