select * from test 数据: A B C 1 1 1 1 2 2 1 3 3 2 2 5 3 4 6 ---将B栏位值相同的对应的C 栏位值加总 select a,b,c, SUM(C) OVER (PARTITION BY B) C_Sum from test A B C C_SUM 1 1 1 1 1 2 2 7 2 2 5 7 1 3 3 3 3 4 6 6 ---如果不需要已某个栏位的值分割,那就要用 null eg: 就是将C的栏位值summary 放在每行后面 select a,b,c, SUM(C) OVER (PARTITION BY null) C_Sum from test A B C C_SUM 1 1 1 17 1 2 2 17 1 3 3 17 2 2 5 17 3 4 6 17 |

主要介绍了Oracle查询中OVER (PARTITION BY ..)用法,内容和代码大家参考一下。
Oracle 语法之 OVER (PARTITION BY ..) 及开窗函数(转载),这个命令很实用,对于分析人员经常用到。
1、 结构:聚合函数()over( partition by 字段1,字段2,字段3 order by 字段 desc/asc range between 数值/date preceding/flowing and 数值/date preceding/flowing) 聚合函数可以是:sum,count,avg,max,min,...
这些排列函数提供了定义一个集合(使用 PARTITION 子句),然后根据某种排序方式对这个集合内的元素进行排列的能力,下面以scott用户的emp表为例来说明rank over partition如何使用。 1)查询员工薪水并连续求和 ...
SELECT col, AVG(value) OVER(PARTITION BY col ORDER BY col) FROM tmp1 ORDER BY col; 2、SUM ( [ DISTINCT | ALL ] expr ) OVER ( analytic_clause ) 例如: --聚合函数 SELECT col, sum(value) FROM tmp1 ...
row_number()over(partition by col1 order by col2)表示根据col1分组,在分组内部根据col2排序,而此函数计算的值就表示每组内部排序后的顺序编号(组内连续的唯一的)。 与rownum的区别在于:使用rownum进行排序的...
sum(sal) over (partition by deptno order by ename) 按部门“连续”求总和 sum(sal) over (partition by deptno) 按部门求总和 sum(sal) over (order by deptno,ename) 不按部门“连续”求总和 sum(sal) over () ...
rank ( ) over ([partition by col] order by col ) dense_rank ( ) over ([partition by col] order by col ) rownumber ( ) over ( [partition by col] order by col ) rank() 是排名的函数,该函数组内...

介绍了 row_number() over(order by column asc) 函数和 row_number() over(partition by column1 order by column2 asc) 的使用实例和方法
第五篇 分析函数简述 ... Partition 子句:Partition by exp1[ ,exp2]... Partition没啥说的,功能强大参数少,主要用于分组,可以理解成select中的group by。不过它跟select语句后跟的group by 子句并不冲突。
oracle分组查询数据 select BFMBIGNAME,projectaddress,...from(select BFMBIGNAME,projectaddress,BFMSMALLNAME,row_number() over (partition by BFMBIGNAME order by REGISTERDATE) id from Projectinfo) where id;
代码如下:Sum() Over ([Partition by ] [Order by ]) Sum() Over ([Partition by ] [Order by ] Rows Between Preceding And Following) Sum() Over ([Partition by ] [Order by ] Rows Between ...
mysql代码-查询每天前三条数据 按照交易价格大到小排序 相当于模拟Oracle Row_Number() OVER (partition by date ORDER BY pay desc)
1、CUME_DIST() OVER([partition_clause] order_by_clause) 返回该行在分组序列中的相对位置,返回值介于0到1之间。注意哟,如果order by的列是desc,则该分组内最大的行返回列值1,如果order by为asc,则该分组内...
For example, a query that requests data generated in the month of October 1994 can scan just the rows stored in the October 1994 partition, rather than rows generated over years of activity....
