MS SQLすべてのテーブルが遅すぎるクエリ

Question

私のクエリに問題があります。私はMS SQLで、患者からすべての関連テーブルを取得しようとしています。ここからすべてがうまくいっています。まずクエリを構築してから実行します。私がそれを実行すると、2分以上かかります。それは長すぎるそして私はすべての私のテーブルにインデックスを持っています。ここで私が達成しようとするものです。

ここに私のクエリはビルドアップだ：

select * from (   
     select (STUFF((
    SELECT ' ' + AA.LEFTJOIN 
    FROM (Select 'LEFT OUTER JOIN ' + A.name + ' WITH (NOLOCK) on (tbpatient.Id = ' + (A.name + '.' + B.Name) + ')' AS LEFTJOIN 
      from sysobjects A Join SysColumns B on (A.id = B.id) 
      Where B.name in ('IdPatient','ImageIdPatient') 
      And not A.name in ('tbrv','tbPatient','tbRV_ToExport','tbRV_Archive','tbRV_LOG_Archives','tbPatients_ToExport', 
      'tbPatientLock','tbPatient_FusionToExport','tbRV_LOG','tbPatient_A1','tbPatient_A2','tbPatient_A3','tbPatient_QVCDetail') 
      And a.type = 'U' And a.Name LIKE 'tb%') AA 
    FOR XML PATH('') 
    ), 1, 2, '') 
) AS query 
union all 
select (STUFF((
    SELECT ' ' + AA.WHERECLAUSE 
    FROM (Select ' And ' + '(' + A.name + '.' + B.Name + ') IS NULL ' AS WHERECLAUSE from sysobjects A Join SysColumns B on (A.id = B.id) 
      Where B.name in ('IdPatient','ImageIdPatient') 
      And not A.name in ('tbrv','tbPatient','tbRV_ToExport','tbRV_Archive','tbRV_LOG_Archives','tbPatients_ToExport', 
      'tbPatientLock','tbPatient_FusionToExport','tbRV_LOG','tbPatient_A1','tbPatient_A2','tbPatient_A3','tbPatient_QVCDetail') 
      And a.type = 'U' And a.Name LIKE 'tb%') AA 
    FOR XML PATH('') 
    ), 1, 2, '') 
) AS query) as AA 

それは戻っています：

を、私は私のコードで最初にこれを追加します。

私は私のVBのコードでこの句を追加します。私は2つのフィールドを連結し、私のクエリを実行したとき

And (tbPatientLettres.IDPatient) IS NULL  
And (tbPatientprofessionnel.IDPatient) IS NULL  
And (tbDossierPatient.IDPatient) IS NULL

And (tbPatientContacts.IDPatient) IS NULL  
And (tbPatient_B1.IDPatient) IS NULL 

where tbpatient.idstatut = 1 And A.Id is NULL And B.Id is NULLが、その後、それは2つ以上の分を取る...誰かが助ける方法を知っています物事？長いポストに感謝して申し訳ありません。

Answer 1

は、私はあなたのクリニックに行っていない患者を取得するには、以下のコードで物事を単純化することができると思う、と私はそれが良い仕事かもしれないと思う：

SELECT Id 
FROM tbpatient 
EXCEPT 
(SELECT IDPatient 
FROM tbPatientLettres 
UNION 
SELECT IDPatient 
FROM tbPatientprofessionnel 
UNION 
SELECT IDPatient 
FROM tbDossierPatient 
... and so on until you get all your tables in here 
) 

また、万が一、あなたドンがある場合IDPatient列のいずれかまたは一部にクラスタ化されていないインデックスがあります。これはもっと速くなければなりません。
