问题 I need to convert a folder with around 4,000 .txt files into a single .csv with two columns: (1) Column 1: 'File Name' (as specified in the original folder); (2) Column 2: 'Content' (which should contain all text present in the corresponding .txt file). Here you can see some of the files I am working with. The most similar question to mine here is this one (Combine a folder of text files into a CSV with each content in a cell) but I could not implement any of the solutions presented there.

问题 I have a SQL query I'm running in SSMS that generates about 8 different resulting datasets (all with different columns). Is there a way to have each of the result sets get out output to a separate tab in Excel without having to copy/paste and result set table individually from SSMS. I know one approach would be to UNION all the results and patch with fake columns (so that the columns line up) and then generate a single output set. But that would then require manually filtering and separating

问题 I'm having troubles with CSV conversion, I'm not that sure on how to do this (not that familiar with CSV conversion, testing this out as a side project) I have a nested dictionary that I want to create into a CSV: I want to set STRONG_AXE and FAST_AXE under the column ITEM_ID Make another column called base which contains the attack values, 10 and 1 , same with attack speed.

问题 I want to save the result of a psql query as an Excel file. ie, I have a table named company with 5 column. I want to execute the query, SELECT column_1, column_2, FROM company; And I just want to save the result of this query as a Excel file. Is it possible in PostgreSQL? If yes then please explain it.

问题 I want to create an csv file using c++, using Qt for application and UI framework. Is there's library for csv file. 回答1: You could basically look into libqxt. Using QxtCsvModel The QxtCsvModel [libqxt.bitbucket.org] class provides a QAbstractTableModel [qt-project.org] for CSV Files. This is perhaps the easiest way possible to read and write csv files without having to parse the csv format to something qt can understand. It’s as simple as using one line of code, for example the following
