Joindre deux requêtes ou une union/union tous

Question

J'ai créé une union tout à partir du code ci-dessous. Je ne suis pas sûr que ce soit ce que je veux. La partie supérieure dans est le groupe dans les plus petits détails. Il compte le nombre d'élèves, par l'école, la note, les résultats des tests par engProf et ethniques. la deuxième requête donne un total d'étudiants ventilés par étudiant, école, niveau et test. Le retour du nombre total d'élèves de deuxième année à l'école x a été soumis au test de mathématiques et x élèves ont passé le test de lecture. L'un sera un résumé de niveau supérieur de l'autre. Je veux les joindre ensemble pour qu'un jeu de données soit utilisé dans un rapport. Aucune suggestion. J'ai essayé un syndicat, je ne sais pas si c'est la meilleure solution.

Answer 1

Ceci est une pratique assez courante avec un tour ... Ajouter dans une colonne d'ordre ou niveau pour obtenir les résultats dans le bon ordre. N'avez pas de valeur Null pour les éléments que vous regroupez car vous ne pouvez pas le commander correctement. Voici un exemple où je fais une liste d'un étudiants de classe et le nombre total:

SELECT class, student_name, count 
    FROM 
    (
    SELECT class, student_name, 0 as count, 1 as ord 
    FROM classlist 
    UNION ALL 
    SELECT class, '' as student_name, count() as count, 2 as ord 
    FROM classlist 
    GROUP BY class 
    ) T 
    ORDER BY class, ord, student_name 

Answer 2

Ne voulez-vous pas juste à gauche rejoindre le 2? Où la table de gauche a le grain le plus fin (plus de détails).

Vous pouvez utiliser un CTE.

With 
Group1 
AS 
(SELECT 
track, 
schoolc, 
schname AS[school], 
grade, 
subtestc AS[ELA/Math], 
EngProf, 
SUM(CASE WHEN (subtestc) IN ('ela','Math') AND tscrtypc ='A'THEN 1 ELSE 0 END) AS [total Students], 
SUM(CASE WHEN (testscore)IN ('A','P') AND subtestc IN ('ela','Math') AND tscrtypc ='A'THEN 1 ELSE 0 END) AS [At/Above], 
SUM(CASE WHEN (testscore)IN ('B','BB','FBB') AND subtestc IN ('ela','Math') AND tscrtypc ='A'THEN 1 ELSE 0 END) AS [Below], 
SUM(CASE WHEN (subtestc) IN ('ela','Math') AND tscrtypc ='A' AND(ethnic)='White (not Hispanic)' THEN 1 ELSE 0 END) AS [Total White(not Hispanic)], 
SUM(CASE WHEN (testscore)IN ('A','P') AND subtestc IN ('ela','Math') AND tscrtypc ='A' AND(ethnic)='White (not Hispanic)'THEN 1 ELSE 0 END) AS [White (Total not Hispanic) At/Above], 
SUM(CASE WHEN (testscore)IN ('B','BB','FBB') AND subtestc IN ('ela','Math') AND tscrtypc ='A' AND(ethnic)='White (not Hispanic)'THEN 1 ELSE 0 END) AS [ Total White (not Hispanic)], 
SUM(CASE WHEN (subtestc) IN ('ela','Math') AND tscrtypc ='A' AND(ethnic) <>'White (not Hispanic)' THEN 1 ELSE 0 END) AS [ Total Other Nonwhite students],

Select group1.track,

From Group1 
Left outer join Group2
