如何逐个运行bcp命令

Question

我想在一个批处理文件/脚本中逐个执行15个“bcp命令”。每个命令只有在上一个命令成功执行后才能处理或执行..如果在任何情况下命令都无法执行...脚本应该停止执行......

我试过这个..但我没有得到足够的输出我需要的..

bcp.exe "select * from OrderXpress.dbo.Customers where CustId < 1000" queryout "D:\Customer.dat" -S localhost -U sa -P Sa12345 -E -n  

IF %ERRORLEVEL% > 0 ( PAUSE )

bcp.exe OrderXpress.dbo.Customers out "D:\Customer2.dat" -S localhost -U sa -P Sa12345 -E -n 

IF %ERRORLEVEL% > 0 ( PAUSE )

bcp.exe OrderXpress.dbo.Orders out "D:\Orders.dat" -S localhost -U sa -P Sa12345 -E -n 

IF %ERRORLEVEL% > 0 ( PAUSE )

我相信你缺少的是总脚本停止。您的pause命令暂时保存脚本，但不保存完整脚本。

您应该使用标签来跳转。在下面的脚本中，我添加了标签:error_happened以在出错时跳转到。如果没有错误，那么命令goto :EOF将跳过:error_happened标签。

bcp.exe "select * from OrderXpress.dbo.Customers where CustId < 1000" queryout "D:\Customer.dat" -S localhost -U sa -P Sa12345 -E -n  
IF ERRORLEVEL 1 GOTO error_happened

bcp.exe OrderXpress.dbo.Customers out "D:\Customer2.dat" -S localhost -U sa -P Sa12345 -E -n 
IF ERRORLEVEL 1 GOTO error_happened

bcp.exe OrderXpress.dbo.Orders out "D:\Orders.dat" -S localhost -U sa -P Sa12345 -E -n 
IF ERRORLEVEL 1 GOTO error_happened

goto :EOF

:error_happened
echo,
echo An error has occurred. Script stopped
echo
pause

但是，必须对BCP出现的错误级别进行评论。如果没有正确导出数据行，那么我不确定errorlevel会发生什么。我知道在导入行错误不会导致问题。另见：https://groups.google.com/forum/#!topic/microsoft.public.sqlserver.tools/qzpWuZzJnr4

我有一个解决方法使用-e参数来检查错误。该脚本将是：

bcp.exe "select * from OrderXpress.dbo.Customers where CustId < 1000" queryout "D:\Customer.dat" -e errors.txt -S localhost -U sa -P Sa12345 -E -n  
IF ERRORLEVEL 1 GOTO error_happened
call :check_errorfile

bcp.exe OrderXpress.dbo.Customers out "D:\Customer2.dat" -e errors.txt -S localhost -U sa -P Sa12345 -E -n 
IF ERRORLEVEL 1 GOTO error_happened
call :check_errorfile

bcp.exe OrderXpress.dbo.Orders out "D:\Orders.dat" -e errors.txt -S localhost -U sa -P Sa12345 -E -n 
IF ERRORLEVEL 1 GOTO error_happened
call :check_errorfile

goto :EOF

:check_errorfile
if exist errors.txt (
    FOR %%A IN (errors.txt) DO (
        if %%~zA GTR 0 (
        goto error_happened
        ) else (
        del errors.txt
        )
    )
)
exit /b

:error_happened
echo,
echo An error has occurred. Script stopped
echo
pause

请试试这个......

BEGIN尝试bcp.exe“select * from OrderXpress.dbo.Customers where CustId <1000”queryout“D：\ Customer.dat”-S localhost -U sa -P Sa12345 -E -n

结束

开始捕捉

DECLARE @msg VARCHAR(1000)

SET @msg = ERROR_MESSAGE()

RAISERROR(@msg,16,0)

结束捕捉
