field key1 key2 value
data k1 k11 v11
k1 k13 v12
k1 k13 v13
k2 k21 v21
k2 k22 v22
我想显示 group groupin value
1 1 v11
1 2 v12
1 3 v13
2 1 v21
2 2 v22
------解决方案--------------------
SELECT dense_rank() over(PARTITION BY KEY1 ORDER BY key1) AS
GROUP , row_number() over(PARTITION BY key1
ORDER BY key1) AS groupin, VALUE
FROM t
这样子试一下。
用dense_rank()这个分析函数来实现。
------解决方案--------------------
select dense_rank() over(PARTITION BY KEY1 ORDER BY key1) "group ",
row_number() over(partition by key1 ORDER BY key1) groupin, "VALUE "
from table1;
