Question

select distinct v1.name 'Machine Name', v1.[user] 'Primary User', CASE

    When v1.Guid in (select distinct v1.guid from vComputer v1
inner join Inv_AddRemoveProgram t1 on v1.Guid = t1._ResourceGuid
inner join Inv_OfficeSuiteVersions3 t2 on v1.guid = t2._ResourceGuid
where t1.DisplayName = 'Microsoft Office Professional Plus 2007' and t1.InstallFlag = '1'
and t2.Outlook2007Ver <> 'Not Present')
    Then 'Microsoft Office Professional Plus 2007'
    When v1.Guid in (select distinct v1.guid from vComputer v1

and t2.Outlook2010Ver <> 'Not Present')
    Then 'Microsoft Office Professional Plus 2010'
    When v1.Guid in (select distinct v1.guid from vComputer v1

    End [Office Version], v2.[Location by Subnet] 'Location'

from vComputer v1

inner join vcomputerlocations v2 on v1.Guid = v2.Guid

and v1.Name like 'USSD%'

and v1.Guid not in (select Guid from CollectionMembership where FilterName = 'Software Delivery Exclusions')

or v1.Name like 'USSF%'

and v1.Guid not in (select Guid from CollectionMembership where FilterName = 'Software Delivery Exclusions')

or v1.Name like 'USSEA%'

and v1.Guid not in (select Guid from CollectionMembership where FilterName = 'Software Delivery Exclusions')

or v1.Name like 'USBES%'

and v1.Guid not in (select Guid from CollectionMembership where FilterName = 'Software Delivery Exclusions')

or v1.Name like 'USCAM%'

and v1.Guid not in (select Guid from CollectionMembership where FilterName = 'Software Delivery Exclusions')

order by 3,4,1

Answer 1

1. アプリケーションで必要な場合は、クエリの末尾から order by を削除して並べ替えます。

2. 結合でインデックスを使用できないため、可能であればこのクエリを書き直す必要があります -> 「USSF%」などのフィルタを使用する場合、SQL エンジンはインデックスを使用できません。

3. ない場合は、FilterName にインデックスを作成します。

Answer 2

繰り返し操作に共通テーブル式、一時テーブル、またはテーブル変数を使用することを検討し、さまざまな Guid が主キーであると想定して、表示またはフィルター名の列ではなく、それらの値を使用して選択してみてください。

おそらくこのようなもの：

WITH a AS
(
    SELECT v1.Guid, v1.Name, v1.[user], t1.DisplayName from vComputer v1
    INNER JOIN Inv_AddRemoveProgram t1 on v1.Guid = t1._ResourceGuid
    INNER JOIN Inv_OfficeSuiteVersions3 t2 on v1.Guid = t2._ResourceGuid
    WHERE t1.InstallFlag = '1' 
    AND
    (t1.PrimaryKey = '2007 PrimaryKey Value' AND t2.Outlook2007Ver <> 'Not Present')
    OR
    ((t1.PrimaryKey = '2010 PrimaryKey Value' AND t2.Outlook2010Ver <> 'Not Present') --etc etc
),

b AS
(
    SELECT Guid FROM CollectionMembership WHERE FilterName = 'Software Delivery Exclusions'
) -- would be better to search by primary key

SELECT  a.*, v2.[Location by Subnet] 
FROM a INNER JOIN vcomputerlocations v2 on a.Guid = v2.Guid  
LEFT JOIN b ON a.Guid = b.Guid 
WHERE b.Guid IS NULL 

完璧ではないかもしれませんが、理解していただければ幸いです
