选择具有至少1个匹配列值的行与特定行

Question

我一直在尝试编写一个Hive查询，它允许我选择具有至少1个匹配特定列值的所有行，即一行。，

---

City     |   Mon  |  Tue  |  Wed  |  Thu  |  Fri  |  Sat  |  Sun
-----------------------------------------------------------------
Houston  |  Rain  |  Fog  |  Sun  |  Fog  |  Rain |  Sun  |  Sun
Denver   |  Sun   |  Sun  |  Sun  |  Sun  |  Fog  |  Sun  |  Sun
Seattle  |  Rain  |  Sun  |  Sun  |  Rain |  Rain |  Sun  |  Rain
Boston   |  Snow  |  Sun  |  Sun  |  Snow |  Snow |  Fog  |  Rain
Dallas   |  Sun   |  Sun  |  Sun  |  Sun  |  Sun  |  Rain |  Sun
StLouis  |  Rain  |  Sun  |  Fog  |  Rain |  Sun  |  Sun  |  Sun

现在我想在“西雅图”的同一天选择所有有“雨”的城市 结果就是，

City     |   Mon  |  Tue  |  Wed  |  Thu  |  Fri  |  Sat  |  Sun
-----------------------------------------------------------------
Houston  |  Rain  |  Fog  |  Sun  |  Fog  |  Rain |  Sun  |  Sun
Seattle  |  Rain  |  Sun  |  Sun  |  Rain |  Rain |  Sun  |  Rain
Boston   |  Snow  |  Sun  |  Sun  |  Snow |  Snow |  Fog  |  Rain
StLouis  |  Rain  |  Sun  |  Fog  |  Rain |  Sun  |  Sun  |  Sun

感谢任何帮助。感谢

如果您将Seattle行加入到每一行，那么您可以逐列进行比较，以确定是否应该在结果中保留每一行：

SELECT
    t.*
FROM
    table t
INNER JOIN
    (SELECT * FROM table WHERE City = 'Seattle') s
WHERE
    (s.Mon = 'Rain' AND t.Mon = 'Rain') OR
    (s.Tue = 'Rain' AND t.Tue = 'Rain') OR
    (s.Wed = 'Rain' AND t.Wed = 'Rain') OR
    (s.Thu = 'Rain' AND t.Thu = 'Rain') OR
    (s.Fri = 'Rain' AND t.Fri = 'Rain') OR
    (s.Sat = 'Rain' AND t.Sat = 'Rain') OR
    (s.Sun = 'Rain' AND t.Sun = 'Rain')
;
