如何获取不同页码的记录

Question

如何获得以下输出：-

Table 包含：-

+--------+-------------+-----------+
|  word  |  unique id  |  page no  |
+--------+-------------+-----------+
|  tv    |    4444     |     1     |
+--------+-------------+-----------+
|  tv    |    4444     |     1     |
+--------+-------------+-----------+
|  tv    |    4444     |     2     |
+--------+-------------+-----------+
|CDPlayer|    8888     |     1     |
+--------+-------------+-----------+
|CDPlayer|    8888     |     1     |
+--------+-------------+-----------+
|  Watch |    1212     |     1     |
+--------+-------------+-----------+
|  Watch |    1212     |     2     |
+--------+-------------+-----------+

我想记录哪些重复页码不同，即如果单词具有相同的页码则忽略该记录，如果单词具有相同的页码以及不同的页码则收集该记录

输出：-

+--------+-------------+-----------+
|  word  |  unique id  |  page no  |
+--------+-------------+-----------+
|  tv    |    4444     |     1     |
+--------+-------------+-----------+
|  tv    |    4444     |     2     |
+--------+-------------+-----------+
|  Watch |    1212     |     1     |
+--------+-------------+-----------+
|  Watch |    1212     |     2     |
+--------+-------------+-----------+

任何想法或建议，怎么做？

Answer 1

这个可能有帮助：

SELECT DISTINCT m.* FROM mytable m 
QUALIFY COUNT(DISTINCT page_no) OVER (PARTITION BY word,unique_id ) > 1;

+-------+-----------+---------+
| WORD  | UNIQUE_ID | PAGE_NO |
+-------+-----------+---------+
| tv    |      4444 |       1 |
| tv    |      4444 |       2 |
| Watch |      1212 |       1 |
| Watch |      1212 |       2 |
+-------+-----------+---------+
