ORA-00907:缺少右括号

Question

SELECT * FROM (
SELECT SUM(A.Precio)AS "Total gastado", B.email FROM ARTICULO_EVENTO A
    JOIN (C.email FROM PEDIDO_ARTICULO_EVENTO C)B
    ON(B.email=A.email)
WHERE B.FechaHora > TO_DATE('20-08-2012', 'MM-DD-YYYY')
GROUP BY (B.email)
ORDER BY SUM(A.Precio) DESC
)
WHERE ROWNUM <=5;

ORA-00907:缺少右括号。在第三行。

？为什么会出现这个错误？

Answer 1

试一下这个，您在子查询中忘记了select关键字，并留下了一个";"：

SELECT * FROM (
SELECT SUM(A.Precio)AS "Total gastado", B.email FROM ARTICULO_EVENTO A
    JOIN (select C.email FROM PEDIDO_ARTICULO_EVENTO C)B
    ON(B.email=A.email)
WHERE B.FechaHora > TO_DATE('20-08-2012', 'MM-DD-YYYY')
GROUP BY (B.email)
ORDER BY SUM(A.Precio) DESC
)
WHERE ROWNUM <=5;
