ms sql server 2008

SELECT Action.* 
FROM   Mailing 
       INNER JOIN ActionCategoryMailingBunch 
         ON Mailing.MailingID = ActionCategoryMailingBunch.MailingID 
       INNER JOIN ActionCategory 
         ON ActionCategoryMailingBunch.ActionCategoryID = 
            ActionCategory.ActionCategoryID 
       INNER JOIN Action 
         ON ActionCategory.ActionCategoryID = Action.ActionCategoryID 
WHERE  ( Mailing.MailingID = 7 ) 
       AND ( Mailing.MailingID NOT IN (SELECT MailingID 
                                       FROM   MailingReport) ) 
       AND ( Action.ActionID NOT IN (SELECT ActionID 
                                     FROM   MailingReport) ) 
       AND ( ActionCategoryMailingBunch.MailingBunchStatusID = 4 )  

especially this block

(Mailing.MailingID NOT IN (SELECT MailingID FROM  MailingReport)) 
AND (Action.ActionID NOT IN (SELECT ActionID FROM  MailingReport))

Answer 1

Add the below code in the select statement

Left Join MailingReport MR on MR.ActionID = Mailing.MailingID

Add the below code in Where clause

(MR.ActionID is null)

Performance upgrade due to following block

(Mailing.MailingID NOT IN (SELECT MailingID FROM  MailingReport)) 

Final Query

SELECT Action.* 
FROM   Mailing 
       INNER JOIN ActionCategoryMailingBunch 
         ON Mailing.MailingID = ActionCategoryMailingBunch.MailingID 
       INNER JOIN ActionCategory 
         ON ActionCategoryMailingBunch.ActionCategoryID = 
            ActionCategory.ActionCategoryID 
       INNER JOIN Action 
         ON ActionCategory.ActionCategoryID = Action.ActionCategoryID 
         Left Join MailingReport MR on MR.ActionID = Mailing.MailingID
WHERE  ( Mailing.MailingID = 7 ) 
       --AND ( Mailing.MailingID NOT IN (SELECT MailingID 
       --                                FROM   MailingReport) ) 
       AND
       (MR.ActionID is null)
       AND ( Action.ActionID NOT IN (SELECT ActionID 
                                     FROM   MailingReport) ) 
       AND ( ActionCategoryMailingBunch.MailingBunchStatusID = 4 ) 

Similarly you can do for the second block
Performance due to second block

AND (Action.ActionID NOT IN (SELECT ActionID FROM  MailingReport))

Final Query for both blocks

SELECT Action.* 
FROM   Mailing 
       INNER JOIN ActionCategoryMailingBunch 
         ON Mailing.MailingID = ActionCategoryMailingBunch.MailingID 
       INNER JOIN ActionCategory 
         ON ActionCategoryMailingBunch.ActionCategoryID = 
            ActionCategory.ActionCategoryID 
       INNER JOIN Action 
         ON ActionCategory.ActionCategoryID = Action.ActionCategoryID 
         Left Join MailingReport MR on MR.ActionID = Mailing.MailingID
         Left Join MailingReport MRA on MRA.ActionID = Action.ActionID
WHERE  ( Mailing.MailingID = 7 ) 
       AND
       (MR.ActionID is null)
       AND
       (MRA.ActionID is null)
       AND ( ActionCategoryMailingBunch.MailingBunchStatusID = 4 )
