问题 How to find 'last SUNDAY DATE' through batch command? what I was trying is echo %date:~4,2%%date:~7,2%%date:~10,4% this is good for current date but for last Sunday date... can anyone suggest any logic through batch. 回答1: Windows PowerShell: [DateTime]::Now.AddDays(-1 * [DateTime]::Now.DayOfWeek.value__) Sorry the environment variable %date% in Batch (.bat) files sounds uneasy to do calculations. 来源： https://stackoverflow.com/questions/33773683/how-to-find-last-sunday-date-through-batch

问题 I have a file (1.8 Mb) that has 1 single (very long) row of text. The values on that row are generally separated by 13 blank spaces.

问题 I have a problem with my BATCH file... Whatever is written on the first line, it says: [command] is not a command. Like so: @ECHO OFF I get this output: [C:\folder (path)]>´╗┐@ECHO OFF ´╗┐@ECHO is not a command It does the same even in a clear batch file(nothing except @ECHO OFF in it). Please help! 回答1: You are seeing the BOM (Byte Order Mark) of the file, probably utf-8 encoded. Open with an editor and save the file with ANSI encoding. 来源： https://stackoverflow.com/questions/28836113/not

问题 Is there any way to have a Windows batch file directly input SQL statements without calling a script? I want the batch file to login to SQL and then enter in the statements directly.
