问题 How to format dates during the process of creating Hive tables? I've currently been dumping some data into a discovery environment at work and storing dates as string, because if I format them as a DATE or TIMESTAMP the values are null. Here's what the raw data looks like: 12/07/2016 05:07:28 PM My understanding is that Hive accepts dates in this format yyyy-mm-dd hh:mm:ss I can format these using a select statement: select id, receipt_dt, from_unixtime(unix_timestamp(receipt_dt ,'MM/dd/yyyy'

问题 dear as you can see in uploaded picture it is an excel sheet downloaded from data logger to record in wind speed every hour the problem that time sequence not change () in row 87 to 108 it is data from 12/November/2014 2:00 Am to 12/November/2014 11:pm the row 109 suppose to be 13/November/2014 12:00 AM (13/11/2014 12:00 AM )but it is change to 11/13/2014 12:00 AM so any have solution to this matter 回答1: "no the data is downloaded not imported" <--- what they mean is.. when you have the

问题 When you write a number of doubles to a file, in which format are they stored? Is it in byte format or string format? E.g. given 0.00083231. Is it stored with 10 bytes, where each byte represents one digit? Or is it stored as only 8 bytes, since the size of a double is 8 bytes? Assume that the language used is C++. 回答1: If you choose to write text, e.g. with formatted output like file << x , you get text. If you choose to write bytes, e.g. with unformatted output like file.write(&x, sizeof x)

问题 I need to call Format function to return the following strings: 1.0 -> "1 or 1.0" 1.01 - > "1.01" 1.001 - > "1.001" 1.0000001 -> "1.0000001" It it possible? The standard format string %0:f returns only two digits after the point (for example, "1.01" ). 回答1: Use the %g general format string: {$APPTYPE CONSOLE} uses System.SysUtils; begin Writeln(Format('%g', [1.0])); Writeln(Format('%g', [1.01])); Writeln(Format('%g', [1.001])); Writeln(Format('%g', [1.0000001])); end. Output 1 1.01 1.001 1

问题 I am struggeling in writing the output of my code to a txt file while keeping the format. Here is the code: import os # Compute matrix titles = ['Filename', 'Date'] matrix = [titles] for directory, __, files in os.walk('MY_DIRECTORY'): # replace with actual directory path for filename in files: with open(os.path.join(directory, filename)) as f: name, date = f.readline().strip().split() print(name) row = [name, date.split('.')[-1]] for line in f: header, value = line.strip().split(':') if len

问题 I would like to know how to conditionally control formats as below: Cell "A" can have several different inputs. Depending on what, it gets colored formatted. Cell "B" can have a value or not. If it doesn't have it it should stay unformatted. If it has a value it should have the same color format as cell "A". If cell "A" changes it should change the color format in cell "B" also, without changing the value in cell "B". Can someone help me? 回答1: I'm not entirely sure I understand your question

问题 I can't seem to find any texture format with more than 32 bit (GL.RGBA). Is this not supported by WebGL ? 回答1: By 32bit you mean where each element is 32bit itself or each element is 8bits and in sum they are 32 bits (8 bits of red, 8 bits of green, 8 bits of blue, 8 bits of alpha)? In any case there are extensions for 32bit float formats in WebGL so 32bits of red, 32bits of green, 32bits of blue, 32bits of alpha which is 128bit texture format. Those extensions are OES_texture_float. Let's

问题 This question already has answers here : Determine if uploaded file is image (any format) on MVC (10 answers) Closed 3 years ago . I work with c# and asp.net I created a webpage with a web form where you enter your information in order to submit it.

问题 I'm writing a code using python to generate a point shapefile within ArcMAP. I have a 1000 random possibilities (in FileA), and I need to try all of them. The FileA is the index of the position of FileB. In addition, for each sequence generated I'm looking at the evolution of the area of the Voronoi polygon from 3 points to 50 points in each sequence that contains a total of 50 points. When I run the code, I have this message which confuse me: tempXYFile.writerow('{0},{1}'.format(coordinates
