Question

以下のクエリを最適化してパフォーマンスを向上させていただけませんか? コストを下げることはできますか？

SELECT this_.id               AS id1_20_0_, 
       this_.version          AS version2_20_0_, 
       this_.domain           AS domain4_20_0_, 
       this_.createdate       AS createda5_20_0_, 
       this_.lastmodifydate   AS lastmodi6_20_0_, 
       this_.ownerid          AS ownerid7_20_0_, 
       this_.timeperiod       AS timeperi8_20_0_, 
       this_.type             AS type9_20_0_, 
       this_.capturesource    AS capture10_20_0_, 
       this_.value            AS value11_20_0_, 
       this_.siteid           AS siteid12_20_0_, 
       this_.lastmodifyuserid AS lastmod13_20_0_, 
       this_.classid          AS classId3_20_0_ 
FROM   dbo.pcwdepconstraints this_ 
WHERE  this_.classid = 65 
       AND this_.ownerid = 200000000001 
       AND ( this_.capturesource IS NULL 
              OR this_.capturesource IN ( 1073741826, 1073741827, 0, 1, 2 ) ) 

以下の列で ix2_pcwdepcons を再作成しましたが、それでも実行計画とそのコストに変更はありません。

( this_.id , 
       this_.version   , 
       this_.domain ,
       this_.createdate  ,
       this_.lastmodifydate,

       this_.timeperiod  ,
       this_.type  , 
        this_.value   ,       
       this_.siteid       
       this_.lastmodifyuserid )
