mysql,
Add a grouping clause to that query, ie
SELECT
packageItemID,
SUM(packageItemPrice),
( SELECT SUM(c.packageCreditAmount)
FROM packageCredit c
WHERE c.packageCreditItemID = packageItemID
) AS CreditSum,
( SELECT SUM(t.packageItemTaxAmount)
FROM packageItemTax t
WHERE t.pac
mysql,
My Left Joins are Doubling the SUM()
SELECT packageItemID, packageItemName,packageItemPrice
,SUM(packageItemTaxAmount) as packageItemTaxAmount
,SUM(packageCreditAmount) as packageCreditAmount
FROM packageItem
LEFT JOIN packageCredit ON packageItemID=packageCreditItemID
LEFT JOIN
