comma

问题 I have a gzip file with data field separated by commas. I am currently using PigStorage to load the file as shown below: A = load 'myfile.gz' USING PigStorage(',') AS (id,date,text); The data in the gzip file has embedded characters - embedded newlines and commas. These characters exist in all the three fields - id, date and text. The embedded characters are always within the "" quotes. I would like to replace or remove these characters using Pig before doing any further processing. I think I

问题 When I used Loadrunner, it can read data from a csv file. As we know , csv file is separated by a comma. The question is, if the parameter in csv has comma itself, the string will be separated to several segments. That is not I want to get. How can we get the original data with comma in it? 回答1: When data has a comma, use an escape character to store the data in the parameter. For example, if the name is 'Smith, John', it can be stored as Smith\, John in the Loadrunner data file. 回答2: When

问题 I have imported a csv file using pandas. My dataframe has multiple columns titled "Farm", "Total Apples" and "Good Apples". The numerical data imported for "Total Apples" and "Good Apples" contains commas to indicate thousands e.g. 1,200 etc. I want to remove the comma so the data looks like 1200 etc. The variable type for the "Total Apples" and "Good Apples" columns comes up as object. I tried using df.str.replace and df.strip but have not been successful. Also tried to change the variable

问题 I am having an issue with Excel not saving my files properly. I have a list of data which is organized into three columns: String String INt. I want to read this file into a Java program to perform some calculations. Excel exporting as a .csv file causes me to lose significant data as a result of the native UTF-8 encoding. I can save it as a UTF-16 .txt file however, I get another annoying result. If i insert columns of commas between each field field it saves the commas with quotes around it

问题 I'm heaving trouble finding the right regex for decimal numbers which include the comma separator. I did find a few other questions regarding this issue in general but none of the answers really worked when I tested them The best I got so far is: [0-9]{1,3}(,([0-9]{3}))*(.[0-9]+)? 2 main problems so far: 1) It records numbers with spaces between them "3001 1" instead of splitting them to 2 matches "3001" "1" - I don't really see where I allowed space in the regex. 2) I have a general problem

问题 i am trying develop a code to restrict TextBox using C# to only allow numbers entry + comma(",") or dot(".") + only 2 numbers after dot or comma So this way see possible numbers that can entry: 3213,04 = OK 3211,664 = Not 32.31 = OK 32.3214 = Not 334,,00 = Not 3247,.00 = Not 214.,00 = Not 32.. = Not 8465,0 = Ok 654.0 = Ok Understood My goal ? I developed code bellow private void txtValormetrocubico_KeyPress(object sender, KeyPressEventArgs e) { if (txtValormetrocubico.TextLength >= 0 && (e

问题 This question already has answers here : Closed 7 years ago . Possible Duplicate: C++ Comma Operator I came across unexpected (to me at least) C++ behavior today, shown by the following snippit: #include <iostream> int main() { std::cout << ("1", "2") << std::endl; return 0; } Output: 2 This works with any number of strings between the parentheses. Tested on the visual studio 2010 compiler as well as on codepad. I'm wondering why this compiles in the first place, what is the use of this

问题 Suppose we have a simple query like this: SELECT x FROM t WHERE t.y = z If we have one record in the result set, I want to set variable @v to that one value. If we have two or more records, I'd like the results to be separated by a comma and a space. What is the best way to write this T-SQL code? Example: result set of 1 record: Value1 result set of 2 records: Value1, Value2 result set of 3 records: Value1, Value2, Value3 回答1: this will give you the list of values in a comma separated list

问题 I'm not new to R but I am relative new to regular expression. A similar question can be found in here. An example is if I use > strsplit("UK, USA, Germany", ", ") [[1]] [1] "UK" "USA" "Germany" but I want to get [[1]] [1] "UK, USA" "Germany" Another example is > strsplit("London, Washington, D.C., Berlin", ", ") [[1]] [1] "London" "Washington" "D.C." "Berlin" and I want to get [[1]] [1] "London, Washington, D.C." "Berlin" Definitely Washington, D.C. should not be not divided into two parts,
