所选记录的百分比-SQL

我试图编写SQL来确定两个百分比。问题是我的百分比是根据运行表中的所有表项计算的。我希望我的百分比基于所选记录的“总和”和“计数”。我希望这是有道理的

SELECT
      TEST.TS_NAME /*Test.Test Name*/ AS "Test Name" ,
      Count(TEST.TS_NAME)   As "Executions" ,
      SUM(RUN.RN_DURATION) AS "Durtion Summary"  ,
      Round(((count(RUN.RN_TEST_ID)/(SELECT count(RUN.RN_TEST_ID) FROM RUN  )))*100,2)as "Execution Percentage" ,
      Round(((SUM(RUN.RN_DURATION)/(SELECT SUM(RUN.RN_DURATION) FROM RUN)))*100,2)as "Duration Percentage"
FROM
      RUN INNER JOIN  TEST ON RUN.RN_TEST_ID =  TEST.TS_TEST_ID
WHERE
       TEST.TS_TYPE = 'QUICKTEST_TEST' AND  (TEST.TS_NAME Not Like 'FIN - Revenue Consignment%' AND  TEST.TS_NAME NOT LIKE 'WMIM - 053 ZIGO POSTO - Type UB, ZUS, ZM, ZP ZS - Test Case 49')

group by  TEST.TS_NAME
having count(TEST.TS_NAME) > 1
Order by "Duration Percentage" DESC, "Execution Percentage" DESC

考虑提供样本数据和期望的输出，基于它来说明你的问题地点，计数和总和从内部，并使用它们为中心计算，谢谢，我能够解决这个问题，使用“过（）”在我的百分比计算中。
