Fehlender Operator in SQL-Abfrage

Question

Ich versuche, eine Baseball-Datenbank von MS Access abzufragen, aber meine SQL-Anweisung bleibt auf einem fehlenden Operator stecken. Im Folgenden finden Sie die SQL-Abfrage, die ich vorbei:

SELECT 
    Master.nameFirst, Master.nameLast, 
    Master.nameFirst + ' ' + Master.nameLast as FULLNAME, 
    (SUM(Batting.H) + SUM(Batting.BB) + SUM(Batting.HBP))/(SUM(Batting.AB) + SUM(Batting.BB) + SUM(Batting.HBP)) as OBP, 
    SUM(Batting.H)/(SUM(Batting.H) + SUM(Batting.BB) + SUM(Batting.HBP)) as HitP, 
    (SUM(Batting.2B) + SUM(Batting.3B) + SUM(Batting.HR))/SUM(Batting.H) as ExtraP, 
    SUM(Batting.HR)/(SUM(Batting.2B) + SUM(Batting.3B) + SUM(Batting.HR)) as HRP, 
    SUM(Batting.3B)/(SUM(Batting.2B) + SUM(Batting.3B)) as TriplePerc, 
    SUM(Batting.HBP)/(SUM(Batting.BB) + SUM(Batting.HBP)) as HBPP 
FROM 
    Master 
INNER JOIN 
    Batting ON Master.playerID = Batting.playerID 
WHERE 
    (Batting.playerID IN (SELECT playerID 
          FROM Master 
          WHERE (nameFirst = 'Ryan' AND nameLast = 'Howard')) 

Der fehlende Bedienfehler scheint auf diesem einzigen Ausdruck zu konzentrieren:

(SUM(Batting.2B) + SUM(Batting.3B) + SUM(Batting.HR))/SUM(Batting.H) as ExtraP 

Aber ich etwas falsch mit ihm ehrlich gesagt nicht sehen. Was vermisse ich?

Answer 1

Auch nur einen Vorschlag zu machen, wenn Sie Aliase verwenden, und Ihre SQL-Format, können Sie Ihren Code leichter zu lesen, zu verstehen und zu debuggen finden:

SELECT m.nameFirst, m.nameLast, 
    m.nameFirst + ' ' + m.nameLast FULLNAME, 
    (SUM(b.H) + SUM(b.BB) + SUM(b.HBP))/
    (SUM(b.AB) + SUM(b.BB) + SUM(b.HBP)) OBP, 
    SUM(b.H)/(SUM(b.H) + SUM(b.BB) + SUM(b.HBP)) HitP, 
    (SUM(b.2B) + SUM(b.3B) + SUM(b.HR))/SUM(b.H) ExtraP, 
    SUM(b.HR)/(SUM(b.2B) + SUM(b.3B) + SUM(b.HR)) HRP, 
    SUM(b.3B)/(SUM(b.2B) + SUM(b.3B)) TriplePerc, 
    SUM(b.HBP)/(SUM(b.BB) + SUM(b.HBP)) HBPP 
FROM Master m JOIN Batting b 
    ON b.playerID = m.playerID 
    and b.playerId IN 
     (SELECT playerID FROM Master 
     WHERE(nameFirst = 'Ryan' 
      AND nameLast = 'Howard') 

Answer 2

Es sind die vier Zeilen wie:

SUM(Batting.H)/(SUM(Batting.H) + SUM(Batting.BB) + SUM(Batting.HBP)) as HitP, 

sollte sein:

SUM(Batting.H)/((SUM(Batting.H) + SUM(Batting.BB) + SUM(Batting.HBP)) as HitP, 

oder:

SUM(Batting.H)/(SUM(Batting.H) + SUM(Batting.BB) + SUM(Batting.HBP) as HitP,

Oh mein Gott, waren alle falsch. Es ist die schließende Klammer, die fehlt - oder lassen Sie die erste öffnende Klammer weg:

WHERE 
    (Batting.playerID IN (SELECT playerID 
          FROM Master 
          WHERE (nameFirst = 'Ryan' AND nameLast = 'Howard'))
