子查询返回超过 1 行

出现错误：#1242 -执行此操作时

SELECT `Index` , `FundName` ,Count(*), 
    (SELECT COALESCE(sum(b.PricePerWeek),0) 
     FROM tbl_FundSubscriptions
     WHERE DATE_SUB(CURDATE(),INTERVAL 7 DAY) <= SubscribeDt  
     GROUP BY FundIDSend)

FROM tbl_FundSubscriptions b, tbl_FundStatic a

WHERE a.FundID = b.FundIDSend

AND FundIDSend IN 
    (SELECT FundID
     FROM tbl_FundStatic
     WHERE UserID = '14')

GROUP BY a.FundName,a.Index

可能出了什么问题？

谢谢

What could be wrong?

这是您要查找的查询吗？不知道您的表结构，我们永远不会知道，但这会执行您的查询似乎已缩进的操作。（这有什么意义吗？）

SELECT `Index`, `FundName`, COUNT(*), 
    (SELECT SUM(`PricePerWeek`)
     FROM `tbl_FundSubscriptions`
     WHERE DATE_SUB(CURDATE(),INTERVAL 7 DAY) <= `SubscribeDt` 
           AND `FundIDSend` = `tbl_FundStatic`.`FundID`)

FROM `tbl_FundStatic`

WHERE `UserID` = '14'

Is this the query you're looking for? Not knowing your table structure, we'll never know, but this does what your query appears to have been indented to do. (Does that make any sense at all?)

SELECT `Index`, `FundName`, COUNT(*), 
    (SELECT SUM(`PricePerWeek`)
     FROM `tbl_FundSubscriptions`
     WHERE DATE_SUB(CURDATE(),INTERVAL 7 DAY) <= `SubscribeDt` 
           AND `FundIDSend` = `tbl_FundStatic`.`FundID`)

FROM `tbl_FundStatic`

WHERE `UserID` = '14'
