如果批处理（.bat）文件中存在错误级别

我试图对SQL命令的结果运行删除命令，但前提是它返回的错误代码为0.下面是我的代码：如果批处理（.bat）文件中存在错误级别

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，我收到一个语法错误，但我看不到我要去哪里错了。任何帮助将是有用的，因为我是批量新手，谢谢！

括号需要一个空间： “d：\ TEMP \ database.bak（” 及其他子句必须和括号在同一行：“）else（”。 –

'如果errorlevel 0'意味着：“如果errorlevel大于或等于0”，即所有的值！用法：'if if not errorlevel 1 '，即：“如果错误级别小于1” – Aacini

试试这个：

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，也许你可以使用一些GOTO语句尝试：

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%
