如果批處理（.bat）文件中存在錯誤級別

我試圖對SQL命令的結果運行刪除命令，但前提是它返回的錯誤代碼爲0.下面是我的代碼：如果批處理（.bat）文件中存在錯誤級別

SqlCmd command... 

REM if SqlCmd command is successful run the below if exist statement 
if errorlevel 0 (

REM if the file exists then delete and exit: 
    if exist D:\Temp\database.bak(
     del "D:\Temp\database.bak" 
     exit /B 
    ) 
REM if the file doesn't exist, exit with error code 1: 
    else(
      echo The file does not exist 
      exit /B 1 
    ) 

) 
REM if SqlCmd is not successful, exit: 
if errorlevel 1 exit /B %errorlevel%

目前，我收到一個語法錯誤，但我看不到我要去哪裏錯了。任何幫助將是有用的，因爲我是批量新手，謝謝！

括號需要一個空間：「d：\ TEMP \ database.bak（」及其他子句必須和括號在同一行：「）else（」。 –

'如果errorlevel 0'意味着：「如果errorlevel大於或等於0」，即所有的值！用法：'if if not errorlevel 1 '，即：「如果錯誤級別小於1」 – Aacini

試試這個：

REM if SqlCmd command is successful run the below if exist statement 
if "%ERRORLEVEL%"=="0" (

REM if the file exists then delete and exit: 
    if exist "D:\Temp\database.bak" (
     del "D:\Temp\database.bak" 
     exit /B 
    ) else (
REM if the file doesn't exist, exit with error code 1:  
     echo The file does not exist 
     exit /B 1 
    ) 

) 
REM if SqlCmd is not successful, exit: 
if "%ERRORLEVEL%"=="1" exit /B %ERRORLEVEL%

或者，也許你可以使用一些GOTO語句嘗試：

REM if SqlCmd command is successful run the below if exist statement 
if NOT "%ERRORLEVEL%"=="0" GOTO next 

REM if the file exists then delete and exit: 
    if exist "D:\Temp\database.bak" (
     del "D:\Temp\database.bak" 
     exit /B 
    ) else (
REM if the file doesn't exist, exit with error code 1:  
     echo The file does not exist 
     exit /B 1 
    ) 


:next 
REM if SqlCmd is not successful, exit: 
if "%ERRORLEVEL%"=="1" exit /B %ERRORLEVEL%
