通过SQL查询获取百分比

Question

下面是我为从SCCM数据库获取数据而创建的查询。为了获得更多的细节，我遇到了一点麻烦。

select UI.ArticleID ,ui.DateLastModified, 
SUM (CaSe WHEN (AAA.StateID = '2') Then 1 else 0
END) As Install_Count,
sum ( CASE 
WHEN ((AAA.StateID = '2') and  ( OPSYS.Caption0 like 'Microsoft Windows%10%')) THEN  1 else 0
END  ) As 'W10',
sum ( CASE 
WHEN  ((AAA.StateID = '2') and (OPSYS.Caption0 = 'Microsoft Windows 7 Enterprise' or OPSYS.Caption0 = 'Microsoft Windows 7 Entreprise')) THEN  1 else 0
END  ) As 'W7',
sum ( CASE 
WHEN  ((AAA.StateID != '2') and ((OPSYS.Caption0 not like 'Microsoft Windows%10%') and (OPSYS.Caption0 != 'Microsoft Windows 7 Enterprise') and (OPSYS.Caption0 != 'Microsoft Windows 7 Entreprise'))) THEN  1 else 0
END  ) As 'Other',
count(AAA.ResourceID) As 'Total Machines'
FROM v_UpdateInfo UI 
INNER JOIN v_CIAssignmentToCI CIA ON UI.CI_ID = CIA.CI_ID 
INNER JOIN v_CIAssignment ON CIA.AssignmentID = v_CIAssignment.AssignmentID 
Inner Join v_AssignmentStatePerTopic AAA on AAA.AssignmentID = CIA.AssignmentID
inner join v_GS_OPERATING_SYSTEM  OPSYS  on OPSYS.ResourceID=AAA.ResourceID 
where     CIA.AssignmentID = '1234567' and aaa.TopicType = '302'
Group By ui.Title, UI.ArticleID ,ui.DateLastModified

上述查询的输出。

ArticleID   DateLastModified          Install_Count W10 W7  Other   Total Machines
4519998      2019-10-09 02:19:43.000    26          23  3    0         28
4520010      2019-10-09 02:18:04.000    26          23  3    0         28
4520004      2019-10-09 02:20:05.000    26          23  3    0         28

正如您在输出中看到的，Other显示为0。由于Total machines是28，所以我希望Other部分有2台机器。我稍后会调查。

我想从Total Machines中获取Install_Count的百分比(以十进制表示(。

尝试以下片段：

((Install_Count * 100) /  Total Machines) AS Total_Percentage

代码实现：

select UI.ArticleID ,ui.DateLastModified, 
SUM (CaSe WHEN (AAA.StateID = '2') Then 1 else 0
END) As Install_Count,
sum ( CASE 
WHEN ((AAA.StateID = '2') and  ( OPSYS.Caption0 like 'Microsoft Windows%10%')) THEN  1 else 0
END  ) As 'W10',
sum ( CASE 
WHEN  ((AAA.StateID = '2') and (OPSYS.Caption0 = 'Microsoft Windows 7 Enterprise' or OPSYS.Caption0 = 'Microsoft Windows 7 Entreprise')) THEN  1 else 0
END  ) As 'W7',
sum ( CASE 
WHEN  ((AAA.StateID != '2') and ((OPSYS.Caption0 not like 'Microsoft Windows%10%') and (OPSYS.Caption0 != 'Microsoft Windows 7 Enterprise') and (OPSYS.Caption0 != 'Microsoft Windows 7 Entreprise'))) THEN  1 else 0
END  ) As 'Other',
count(AAA.ResourceID) As 'Total Machines',
((SUM (CaSe WHEN (AAA.StateID = '2') Then 1 else 0
END) *100)/count(AAA.ResourceID)) AS Total_percentage
FROM v_UpdateInfo UI 
INNER JOIN v_CIAssignmentToCI CIA ON UI.CI_ID = CIA.CI_ID 
INNER JOIN v_CIAssignment ON CIA.AssignmentID = v_CIAssignment.AssignmentID 
Inner Join v_AssignmentStatePerTopic AAA on AAA.AssignmentID = CIA.AssignmentID
inner join v_GS_OPERATING_SYSTEM  OPSYS  on OPSYS.ResourceID=AAA.ResourceID 
where     CIA.AssignmentID = '1234567' and aaa.TopicType = '302'
Group By ui.Title, UI.ArticleID ,ui.DateLastModified

编辑：

select UI.ArticleID ,ui.DateLastModified, 
SUM (CaSe WHEN (AAA.StateID = '2') Then 1 else 0
END) As Install_Count,
sum ( CASE 
WHEN ((AAA.StateID = '2') and  ( OPSYS.Caption0 like 'Microsoft Windows%10%')) THEN  1 else 0
END  ) As 'W10',
sum ( CASE 
WHEN  ((AAA.StateID = '2') and (OPSYS.Caption0 = 'Microsoft Windows 7 Enterprise' or OPSYS.Caption0 = 'Microsoft Windows 7 Entreprise')) THEN  1 else 0
END  ) As 'W7',
sum ( CASE 
WHEN  ((AAA.StateID != '2') and ((OPSYS.Caption0 not like 'Microsoft Windows%10%') and (OPSYS.Caption0 != 'Microsoft Windows 7 Enterprise') and (OPSYS.Caption0 != 'Microsoft Windows 7 Entreprise'))) THEN  1 else 0
END  ) As 'Other',
count(AAA.ResourceID) As 'Total Machines',
cast(((SUM (CaSe WHEN (AAA.StateID = '2') Then 1 else 0
END) *100)/count(AAA.ResourceID))as decimal(10,2)) AS Total_percentage
FROM v_UpdateInfo UI 
INNER JOIN v_CIAssignmentToCI CIA ON UI.CI_ID = CIA.CI_ID 
INNER JOIN v_CIAssignment ON CIA.AssignmentID = v_CIAssignment.AssignmentID 
Inner Join v_AssignmentStatePerTopic AAA on AAA.AssignmentID = CIA.AssignmentID
inner join v_GS_OPERATING_SYSTEM  OPSYS  on OPSYS.ResourceID=AAA.ResourceID 
where     CIA.AssignmentID = '1234567' and aaa.TopicType = '302'
Group By ui.Title, UI.ArticleID ,ui.DateLastModified
