问题 I have a pandas dataframe and I need to add a new column, which would be based on calculation of specific columns,indicated by a column 'site'. I have found a way to do this with resort to numpy, but always it gives warning about chained index. I am sure there should be better solution, please help if you know. df_num_bin1['Chip_id_3']=np.where(df_num_bin1[key_site_num]==1,df_num_bin1[WB_89_S1]*0x100+df_num_bin1[WB_78_S1],df_num_bin1[WB_89_S2]*0x100+df_num_bin1[WB_78_S2]) df_num_bin1['Chip_id

问题 Never heard of computed column until I needed to set one up today so excuse the stupidity. Here is my create table statement CREATE TABLE [Match]( [Match Org] [nvarchar](10) NULL, [Bypass] [nvarchar](10) NULL, [win] as case when [Match Org] == 'yes' or [Bypass] == 'yes' then 'yes' else 'no' ) ON [PRIMARY] GO I want the win column to automatically compute to yes if either match org or bypass have yes in them... thanks 回答1: CREATE TABLE [Match]( [Match Org] [nvarchar](10) NULL, [Bypass]

问题 I got this pattern: ...,432,3333333,607,5500,617,5000,... ...,66,88,432,22625,607,45330,617,5000,... ...,432,3600000,607,87,617,5000,... From a multi columned csv file delimited by comma, The data should be, the first column should be the key, the second column should be the value, so what I was asked to do is to set all specific keys to zero, and delete the key I need to delete all "607" keys to the csv hence, the above should result to: ...,432,3333333,0,0,617,5000,... ...,66,88,432,22625,0

问题 I have a file with a table like this: I have done that my program returns me the values (max, min and mean) from the line of the gene that I'm looking for. Now my goal is the same, but instead of words, the user will print the number of the column. Ego to obtain these values but only from one column. Here there is my code: #!/bin/bash FICHERO="affy.txt" function OPTIONS { echo "_____________OPTIONS_____________" echo "" echo " 1. Select one gene and its test results" echo " 2. Select one

问题 I have a column in datatable having dates with format dd/MM/yyyy HH:mm . I fill the datatable using the code below which is common for more than 1 select statements so i cannot specify column and their datatype before filling the datatable. Any manipulation after filling the data is acceptable to me. data_adapt = New OracleDataAdapter(query, OraConn) dt = New DataTable data_adapt.Fill(dt) For paging i create a copy of the datatable using skip and take as below dtLineupCopy = New DataTable

问题 I need to create a calculated column that looks at the Field called Forecast Multiplier and if it is 1 use the number in field fp.month1 then if it is 1.5 use fp.month1 and 1/2 of fp.month2 and so on up to 12 months. So I figured I would create a function and then base the calculated column on the function. Here is the function: BEGIN DECLARE @MinInventory as int; DECLARE @MyDate DATETIME = GETDATE() DECLARE @WeekNumber as int = DATEDIFF(WEEK, DATEADD(MONTH, DATEDIFF(MONTH, 0, @MyDate), 0),

问题 I have a table for Library Circulation that have a column named "Delay". This column is a computed column, but it should be changed until the "IsReturned" (another column in this table which is bit) is equal to 0. This means that the delay value should changed and be higher until the member return the book into the library. How can i make this computed column formula ? I try this but it is not a valid formula : dbo.CalculateDelay(Id,IsReturned,Delay) and the function was like that : CREATE

问题 I have a gridview (Order) with three columns: Price Quantity Total I want to multiply Price with Quantity and show the result in Total column of dataGridview. Remember: my dataGridview isn't bind with any table. I am trying this code to achieve my goal but this isn't working means value isn't being returned: private void totalcal() { // is the foreach condition true? Remember my gridview isn't bound to any tbl foreach (DataGridViewRow row in gvSale.Rows) { int a = Convert.ToInt32(row.Cells[3]

问题 How can I define a view that has two calculated fields, for instance... ('TableName'.'BlueSquares' + 'TableName'.'RedSquares') AS TotalSquares, ('TableName'.'BlueCirles' + 'TableName'.'RedCircles') AS TotalCircles ... and create a third calculated field that's based on the first two calculated fields, as in... ('ViewName'.'TotalSquares' + 'ViewName'.'TotalCircles') AS TotalShapes ...? When I reference the first two calculated fields by name, I get a message that the fields are unknown. Thanks
