Question

我在HAB附近的' - '处得到一个缺少的EOF，大部分查询看起来都是正确的。只是不确定如何在HIVE中实施减去。

SELECT
    a.playerID AS ID,
    a.yearID AS yearID,
    (b.HAB - a.EG) AS HAB-EG
FROM 
    (SELECT
        playerID,
        yearID,
        (E/G) AS EG
    FROM fielding
    WHERE (
            yearID > 2005
            AND yearID < 2009
            AND G > 20 
            )
    ) AS a
JOIN
    (SELECT
        id,
        year,
        (hits/ab) AS HAB
    FROM batting
    WHERE( 
            year > 2005
            AND year < 2009 
            AND ab > 40 
            )
    ) AS b ON a.playerID = b.id AND a.yearID = b.year;

Answer 1

当您包含任何其他字符（如空格或短划线）时，别名应使用backtick character (``)个字符引用。
所以使用以下内容：

SELECT
    a.playerID AS ID,
    a.yearID AS yearID,
    (b.HAB - a.EG) AS `HAB-EG`

hive错误，在减去查询时遇到EOF错误
