Basic Python: Rank items in list
Let's come up with a more precise definition of what you are after: Given a list L of numbers, create a list M that contains the valid indices of L, such that M[i] is the index at which the ith element of L occurs, when sorted. Present M as if...
Creating a queue from timestamps SQL
If I understand correctly, you want to assign rank based on the order of the timestamp. The older the timestamp, the higher is the rank in the queue. I would suggest ANALYTIC function. To keep it simple, you could use ROW_NUMBER. For example, SELECT code, cid, ROW_NUMBER() OVER(ORDER BY timestamp_column)...
Creating unique identifier column(1 or zero) Rank () SQL SERVER
declare @test table ( CustNumber int ) insert into @test values (25122134), (25122134), (25122134), (25122136), (25122136) select * , // each CustNumber in partition has the same rank, but different row_number case when (row_number() over (partition by CustNumber order by CustNumber)) = 1 then 1 else 0 end as [Unique]...
SQL: Ranking Sections seperately of a Rollup over multiple columns
I think this will produce what you want: SELECT r.*, row_number() over (partition by (case when colb is null and colc is null and cola is not null then 1 else 0 end), (case when colb is null and colc is null and cola is not null then NULL else...
express percent as a percentage of the total volume rather than ranked volume
Then you want to use a window function to calculate the total volume. I think the logic is: select sum(volume) / sum(sum(volume)) over (partition by EffectiveDate) If volume is an integer, you should convert it to a non-integer number. Otherwise, the division will return an integer -- and be either...
How to rank values in different columns based on a criteria in Python (transferring Excel calculations to Python)?
Usually when working with tabular data in Python, the pandas library is a good tool to reach for. There are lots of ways to do what you want, IIUC, but here's one which shouldn't be too hard to follow. It's mostly to give you a sense for the kinds of...
How to Dense Rank Sets of data
Using the MODEL clause Behold for you are pushing your requirements beyond the limits of what is easy to express in "ordinary" SQL. But luckily, you're using Oracle, which features the MODEL clause, a device whose mystery is only exceeded by its power (excellent whitepaper here). You shall write: SELECT...
partition by values from another related row
sql-server,tsql,partitioning,rank
You can use the following query: SELECT merge_tx_id, merge_from_id, merge_to_id FROM ( SELECT merge_tx_id, merge_from_id, merge_to_id, ROW_NUMBER() OVER (PARTITION BY x.merge1, y.merge2 ORDER BY merge_tx_id DESC) AS rn FROM merge_grp CROSS APPLY (SELECT CASE WHEN merge_from_id < merge_to_id THEN merge_from_id ELSE merge_to_id END AS merge1) AS x CROSS APPLY (SELECT...
Rank by groups sql server
sql,sql-server,group,rank,partition
This is a bit tricky. You can get the grouping for the ids with a trick -- a difference of row numbers. Then you need to get the minimum id for each group, to ensure that the final rank is in the right order. Then you can use then you...
Using Rank or OVER() to create 1 or zero column SQL SERVER
The following does what you want for all films: select r.*, (case when row_number() over (partition by filmname order by date) = 1 then 1 else 0 end) as IsWatchedFirstAndGladiator from results r; For just Gladiator: select r.*, (case when filmname = 'Gladiator' and row_number() over (partition by filmname order...
R data frame rank by groups (group by rank) with package dplyr
Had a similar issue, my answer was sorting on groups and the relevant ranked variable(s) in order to then use row_number() when using group_by. # Sample dataset df <- data.frame(group=rep(c("GROUP 1", "GROUP 2"),10), value=as.integer(rnorm(20, mean=1000, sd=500))) require(dplyr) print.data.frame(df[0:10,]) group value 1 GROUP 1 1273 2 GROUP 2 1261 3 GROUP...
Keep the 2 highest values of each row in a list of matrices r

DELETE FROM Table WHERE 'RANK' > 1
sql,sql-server,delete,conditional,rank

Sorting and ranking a dataframe by date and time in r
I do not share your aversion to datetime objects, which makes this all much simpler: dataf$ts <- strptime(as.character(dataf$Timestamp),'%m/%d/%Y %H:%M') dataf <- dataf[order(dataf$ts),] dataf$ts_rank <- rank(dataf$ts,ties.method = "min") dataf ## hours mins date time Timestamp Actor ts ts_rank ## 19 9 04 4/28/2014 9:04 4/28/2014 9:04 7 2014-04-28 09:04:00 1 ##...
Find top deciles from dataframe by group
r,data.frame,rank,quantile,split-apply-combine
The idiomatic way to do this kind of thing in R would be to use a combination of split and lapply. You're halfway there with your use of lapply; you just need to use split as well. lapply(split(data, data$v1), function(df) { cutoff <- quantile(df$v2, c(0.8, 0.9)) top_pct <- ifelse(df$v2 >...

Selecting SQL TOP N rows from group, row_number, rank not working

I am assuming that you want to get the TOP N result for the sitecode partition with total_cpu_time as order. You can put the Where clause inside if you need to filter data afterwords just filter in inner query. You can use the Row_Number() instead of the rank(), SELECT rs.RunID,rs.SiteCode,rs.procedure_name,rs.total_cpu_time,...

Pandas rank by column value [duplicate]

r rank value in vector
what about creating a new vector with the value appended and rank that ? so creating a loop that for each element of vectora does: rankVector=rank(append(c(a),c1)) And then retrieve the first value of rankVector. The full loop would look like: for (i in seq_along(a) ){ rankVector[i]=rank(append(c(a[i]),c1)) } Cheers !...

Would this work for you? =MAX(0,RANK(O22,$O$9:$O$58, 1)-COUNTIF(O:O,0)) It'll prevent the "0s" from going negative, and leave them displayed as 0's. You could leave the MAX off, however, they'll display as negatives then. Either way .. Alternately, if you can not show "0", but leave the cell blank, it won't consider...
