如何在sqlcmd中使用IF语句

Question

如果在运行过程中出现错误 then echo 'error' else 'success'

sqlcmd -S DANAA-LAPTOP -d NewsWebsite -q "SP_DictionaryMain 'NewsWebsite','NEW'"  
       -o C:\logFile\ReportExE-%date:~-4,4%%date:~-10,2%%date:~-7,2%.txt

Answer 1

try cmd && 和 || 运算符，其中 && 表示前一个命令成功，|| 表示前一个命令失败。

如

mycommand && echo success || echo error

你也可以在括号内编写复合命令

mycommand && (set "somevar=ok" & echo success) || (set "somevar=ko" & echo error)

或者，如果您是运行批处理脚本

mycommand && (
  set "somevar=ok" 
  echo success
) || (
  set "somevar=ko" 
  echo error
)

Also, you need to use the -b switch to force sqlcmd return an ERRORLEVEL that may be captured within batch or command line. This switch also forces sqlcmd to close when an error occurs.

所以，在你的情况下

sqlcmd -b -S DANAA-LAPTOP -d NewsWebsite -q "SP_DictionaryMain 'NewsWebsite','NEW'"  -o C:\logFile\ReportExE-%date:~-4,4%%date:~-10,2%%date:~-7,2%.txt 2>NUL && echo success || echo error

如你所愿echo，错误输出被2>NUL抑制。删除它以查看来自 sqlcmd

的错误消息
