大部分查询都放在变量中，但出于这个问题的目的，我将它们包含在查询中。Margin 是它上面的所有别名查询的总和 ($margin)。
我收到错误消息：
SQLSTATE[HY000]：一般错误：1111 在第 117 行的 company-performance-control.php 中使用组函数无效
这是我的查询：
$margin = $invoicesOut.'-'.$costs.'+'.$creditsIn.'-'.$creditsOut ;
$result = $dbh->query("SELECT CONCAT(MONTH(invoices_out.date), '/', YEAR(invoices_out.date)) AS theDate,
SUM(COALESCE(

0)) AS invoiced,

我把它缩小到这些：
SUM($creditsIn) AS creditsIn
SUM($creditsOut) AS creditsOut
其中定义为：
$creditsIn = 'COALESCE(
(SELECT SUM(net)
FROM credit_notes_supplier, parts_trading_buying
WHERE credit_notes_supplier.partRef = parts_trading_buying.id
AND parts_trading_buying.enquiryRef = enquiries.id)
,0
)' ;
$creditsOut = 'COALESCE(
(SELECT SUM(net)
FROM credit_notes_customer, parts_trading
WHERE credit_notes_customer.partRef = parts_trading.id
AND parts_trading.enquiryRef = enquiries.id)
,0
)' ;
