這個查詢需要永久運行，我該如何編寫它才能運行得更快？

您需要發佈查詢的執行計劃。否則，幾乎不可能獲得適當的幫助。 –

您是否設置了正確的索引並嘗試使用EXPLAIN？ –

你可能也想發佈這個問題http://codereview.stackexchange.com/questions/tagged/sql-server – scsimon

考慮使用Common Table Expressions, Temp Tables or Table Variables進行重複操作，並假設各種Guid是主鍵，請嘗試使用它們的值而不是顯示或過濾器名稱列進行選擇。

像這樣的東西可能：

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

也許不是完美的，但我希望你的想法

感謝您的想法，使用這種方法做了伎倆。非常感謝你！ – user3009669

@ user3009669如果這個答案有幫助，請把它標記爲已接受？ –

從查詢的結束
刪除訂單的，如果你在您的應用程序需要排序。
如果可以，則應該重寫此查詢，因爲它無法在您的連接上使用索引 - >當您使用像「USSF％」這樣的過濾器時，SQL引擎無法使用索引。
如果您沒有任何，請在FilterName上創建索引。
