限制mysql中特定列中的重复行

我有这样一个问题：

select testset,
count(distinct results.TestCase) as runs,
Sum(case when Verdict = "PASS" then 1 else 0 end) as pass,
Sum(case when Verdict <> "PASS" then 1 else 0 end) as fails,
Sum(case when latest_issue <> "NULL" then 1 else 0 end) as issues,
Sum(case when latest_issue <> "NULL" and issue_type = "TC" then 1 else 0 end) as TC_issues
from results 
 join testcases on results.TestCase = testcases.TestCase
where platform = "T1_PLATFORM" AND testcases.CaseType = "M2"
and testcases.dummy <> "flag_1"
group by testset 
order by results.TestCase

我的问题是，这是一个结果表，其中包含多次运行的测试用例。所以 我可以使用不同的测试用例来限制运行，但是当我想要通过并且失败时，因为我使用的是用例，所以我无法消除重复

有什么方法可以实现我想要的吗

需要帮忙吗

谢谢

更新：

TestCases Table : 

ID TestCase CaseType dummy
1  101      M1       flag_0
2  102      M2       flag_1


Results table :

ID TestCase TestSet Verdict latest_issue Platform 
1  101      T1      PASS    NONE         T1_PLATFORM
2  102      T2      FAIL    YES          T2_PLATFORM
3  101      T1      FAIL    YES          T1_PLATFORM

我相信你在追求这样的东西：

select
  testset,
  count(*) as runs,
  sum(passed) as pass,
  count(*) - sum(passed) as fails,
  sum(issues) as issues,
  sum(tc_issues) as tc_issues
from
  ( select 
      r.testset, 
      r.testcase, 
      max(if(r.verdict = 'PASS', 1, 0)) as passed
      max(if(r.latest_issue <> 'NULL', 1, 0)) as issues,
      max(if(r.latest_issue <> 'NULL' and issue_type = 'TC', 1, 0)) as tc_issues,
    from results r
      inner join testcases t on (r.testcase = t.testcase)
    where 
      r.platform = 'T1_PLATFORM' 
      and t.casetype = 'M2'
      and t.dummy <> 'flag_1'
    group by 
      r.testset, 
      r.testcase
  ) as t
group by
  testset
order by 1

注意：我使用了mysql函数，因为它比case语法更简洁。如果你喜欢相反的方式，它应该仍然有效。

如果一个测试用例有一个通过记录和一个失败记录，你想计算哪一个？还是每个人都要1分？请提供一个数据样本和期望的输出。如果一个TestCase2都通过和失败，我想把TestCask当作PASS，不管TestCases有多少个条目，如FAILCan，您可以为结果和测试用例提供表描述。目前尚不清楚哪些数据来自何处。
