.bat文件中的有限循环

Question

我正在使用Notepad ++并尝试在.bat中创建一个有限循环，而不必一遍又一遍地编写相同的命令。我正在研究一个公式

set x=0 
:A 
set y=1 

echo %random% %random%%random% %random% %random% %random% %random% %random% %random% %random% %random%

set Z=%x%+%y% 
goto :A until %Z% = 50  

...但每次它回到:A时，Z都不会保持它已经获得的值。有没有办法可以使线性增长直到Z=50 1}}？

Answer 1

我相信这是你要做的事。

@Echo off

set Z=1 
:A 

echo %random% %random%%random% %random% %random% %random% %random% %random% %random% %random% %random%

set /A Z+=1 
IF NOT "%Z%"=="50" goto :A
pause

Answer 2

...并使用评论中提到的DECLARE @T TABLE ( AccountId INT, UpdateDate DATETIME ) INSERT INTO @T VALUES (123,'11/1/2017 08:00:00:000'), (123,'11/1/2017 20:00:00:000'), (123,'11/2/2017 08:00:00:000'), (456,'11/1/2017 08:00:00:000'), (456,'11/1/2017 14:00:00:000'), (456,'11/1/2017 20:00:00:000'), (789,'11/1/2017 08:00:00:000'), (789,'11/2/2017 08:00:00:000') ;WITH CTE AS ( SELECT SeqNo = ROW_NUMBER() OVER(PARTITION BY AccountId,CAST(UpdateDate AS DATE) ORDER BY UpdateDate), * FROM @T ) SELECT * FROM CTE C1 WHERE EXISTS ( SELECT 1 FROM CTE WHERE AccountId = C1.AccountId AND SeqNo > 1 AND CAST(UpdateDate AS DATE) = CAST(c1.UpdateDate AS DATE) ) ：
