我在Ruby中有下面的列表ID,投票
我目前正在尝试按照列值出现的顺序对in组中的列值进行排名。我的数据集当前如下所示: ID Value Date
1 1 a 1/1/2019
2 1 b 2/5/2018
3 1 a 3/3/2019
4 2 a 6/12/1975
5 2 b 5/4/2017
6 2 b 12/3/2016
7 3 c 1/3/2015
8 3 a 2/1/2015
9 4 a 1/1/1991 我想添加另一个列,使它看起来像这样: ID Value Date Occu
我有一个基于特定次数的“包排名”,一个唯一的客户id已经被发送了一个包。
row_number() over (partition by package.customer_id
order by ship_date.shipped_date) as package_rank
返回的输出如下所示:
+------------+-----------+-----+
|customer_id | ship_date | rank|
+------------+-----------+-----+
| sam | 8/20/2019 | 1 |
我有一个包含以下数据的表格: Action Code Place Date
Remove A Place 1 2019-03-15
Install A Place 2 2019-10-01
Remove A Place 2 2022-07-12
Install A Place 3 2023-01-01 有两种可能的操作。‘'Remove’和'Install‘。我如何在给定的日期找到代码A的位置?例如,2015年的排名为1,2020年的排名为2,2025的
我们有一台服务器,其中一位工程师配置了子网,现在我们被锁在这台服务器之外,我所知道的唯一的访问是IDC的串行控制台(这意味着请IDC工程师来帮助我们)。
被错误配置的东西:
address 192.168.1.9 # Original address there was
netmask 255.255.255.254 # Misconfigured, originally should've been .240
出于好奇-有什么方法可以避免调用IDC并通过SSH连接到这个主机(然后我们可以修复配置)?
我写这个SQL:
INSERT INTO registered (`idc`, `idp`, `date`)
SELECT 'idc'
FROM course,registered
INNER JOIN course c ON c.idc=registered.idc
WHERE course.title='aaa',
(SELECT `idp` FROM participant,registered
INNER JOIN participant ON participant.idp=registered.idp WHERE
我正在为Ida编写一个插件(在python中),它使用Etcd远程密钥值存储系统。我的问题是当我试图获得服务器上的锁时
lock = etcd.Lock(self.client, 'ida_lock')
Should timeout after 30 seconds. Hopefully that is enough.
lock.acquire(blocking=True,lock_ttl=None,timeout=30)
if lock.is_acquired:
data,idc_fil

我有一张表,上面列着多年来的产品销售情况。有一项指标给出了客户每年的总收入,而忽略了销售的产品:
totalRevenueMeasure =
CALCULATE (
SUM ( test[Revenue] ),
ALLEXCEPT ( test, test[company], test[year] )
)
Year company Product revenue totalRevenueMeasure rankx (revenue in year)
