Question

我正在尝试这个查询我的Android应用程序，这与mysql工作正常，但没有给sqlite正确的结果

SELECT cust.Name,cust.ID,billNo,billTime,
(SELECT SUM(b.qty*b.Price*(SELECT (1+(s.tax/100))FROM tbl_stock s 
WHERE b.itemCode=s.itemCode)) 
FROM tbl_billitems b WHERE a.billNo=b.billNo AND a.terminal=b.terminal)AS total ,
(SELECT COUNT(*) FROM tbl_billitems c WHERE a.billNo=c.billNo 
AND a.terminal=c.terminal),terminal FROM tbl_bills a, tbl_customers cust 
WHERE a.ID=cust.ID AND a.billNo IN (SELECT billNo from tbl_billitems)

它使用mysql给出正确的值，但在sqlite中只给出（b.qty * b.Price）的总和

请指导我。提前谢谢

这是我的应用程序代码..希望你有一些想法..

 SELECT t.*, ((summeJ-summeVJ)/summeVJ*100) AS variance
 FROM (SELECT k.ZKUNDENNR, k.ZNAME1,
         (SELECT SUM(vk.ZNETTO) FROM ZPBSROW r LEFT JOIN ZWARENGRUPPEVK vk ON vk.ZPBSROW=r.Z_PK WHERE r.ZKUNDE=k.Z_PK AND ZJAHR=2013 AND ZMONAT>=1 AND ZMONAT<=6) AS summeJ,
         (SELECT SUM(vk.ZNETTO) FROM ZPBSROW r LEFT JOIN ZWARENGRUPPEVK vk ON vk.ZPBSROW=r.Z_PK WHERE r.ZKUNDE=k.Z_PK AND ZJAHR=2012 AND ZMONAT>=1 AND ZMONAT<=6) as summeVJ,
         (SELECT SUM(vk.ZDB_BASIS) FROM ZPBSROW r LEFT JOIN ZWARENGRUPPEVK vk ON vk.ZPBSROW=r.Z_PK WHERE r.ZKUNDE=k.Z_PK AND ZJAHR=2012 AND ZMONAT>=1 AND ZMONAT<=6) as summeDBVJ,
         (SELECT SUM(vk.ZDB_BASIS) FROM ZPBSROW r LEFT JOIN ZWARENGRUPPEVK vk ON vk.ZPBSROW=r.Z_PK WHERE r.ZKUNDE=k.Z_PK AND ZJAHR=2013 AND ZMONAT>=1 AND ZMONAT<=6) as summeDBJ
  FROM ZKUNDE k
 ) t
WHERE summeJ>0
ORDER BY summeJ DESC
LIMIT 0,10
