SQL错误消息语法错误在附近

Question

I was trying to write a query that sort out product that had a sale more than $30, but kept getting the error "Error 1: could not prepare statement (1 near "Where": syntax error)"

SELECT ProductID, ProductName,SUM(Amount) as SUM
From Products
Group by ProductID, ProductName
Where Sum>=30;

Answer 1

GROUP BY is supposed to come after WHERE .

SELECT ProductID, ProductName, SUM(Amount) as SUM 
FROM Products 
WHERE Sum >= 30 
GROUP BY ProductID, ProductName ;

Answer 2

从Product GROUP BY产品ID中选择ProductID，ProductName，SUM（Amount）作为总和，ProductName的sum（amount）> 30;

Answer 3

Use it like this:

SELECT ProductID, ProductName,SUM(Amount) as SUM
From Products Where SUM >= 30 Group by ProductID, ProductName;

Answer 4

Fixed, thanks everyone for help!

SELECT ProductID, ProductName, SUM(Price) FROM Products GROUP BY ProductID, ProductName Having Sum(Price) >= 30
