Question

我正在尝试从bat文件中使用的sqlcmd查询返回单个值。似乎我的sqlcmd查询中使用的语法有一些错误。我对cmd编码很新，任何指导都会有所帮助。我在服务器上使用此查询。

@ECHO off

echo _________________________________________________________

Echo The following inputs are required:
Echo    [1] Database Server Name
Echo    [2] Configuration Type

echo ---------------------------------------------------------
CD %~dp0

SET /p DBSERVER="Enter [1]: "
SET /p CFIGTYPE="Enter [2]: "


echo Deploying...
ECHO %CFIGTYPE%

::-----------------------------------------------TEST1----------------------------------------
IF (%CFIGTYPE% == 'TEST1' ){

for /f %%a in ('sqlcmd -S %DBServer% -v DBServer="%DBServer%" -Q "SET NOCOUNT ON; select ConfigValue FROM SERVICE.dbo.configuration WHERE ConfigOption = 'TEST1' "') 
    do set ColumnVar=%%a
echo %ColumnVar%
CMD \K  
    IF (%ColumnVar% == 'Y'){
        Echo WOHOOOO
        cmd /k
    }
    Else{
        ECHO NOOOOOO
        CMD /K
    }

我的代码在到达sqlcmd部分后才会关闭。

根据评论修改代码：

（不解决问题）

@ECHO off

echo _________________________________________________________

Echo The following inputs are required:
Echo    [1] Database Server Name
Echo    [2] Configuration Type

echo ---------------------------------------------------------

SET /p DBSERVER="Enter [1]: "
SET /p CFIGTYPE="Enter [2]: "


echo Deploying...
ECHO %CFIGTYPE%

::-----------------------------------------------TEST1----------------------------------------
IF "%CFIGTYPE%"=="TEST1" (

for /f %%a in ('sqlcmd -S %DBServer% -v DBServer="%DBServer%" -Q "SET NOCOUNT ON; select ConfigValue FROM SERVICE.dbo.configuration WHERE ConfigOption = 'TEST1' "') 
    do set ColumnVar=%%a
echo %ColumnVar%
    IF "%ColumnVar%"=="Y" (
        Echo WOHOOOO
        cmd /k
    )
    Else (
        ECHO NOOOOOO
        CMD /K
    )
)

新版本：

@ECHO off

echo _________________________________________________________

Echo The following inputs are required:
Echo    [1] Database Server Name
Echo    [2] Configuration Type

echo ---------------------------------------------------------

SET /p DBSERVER="Enter [1]: "
SET /p CFIGTYPE="Enter [2]: "


echo Deploying...
ECHO %CFIGTYPE%

::-----------------------------------------------TEST1----------------------------------------
IF "%CFIGTYPE%"=="TEST1" (

for /f %%a in ('sqlcmd -S %DBServer% -v DBServer="%DBServer%" -Q "SET NOCOUNT ON; select ConfigValue FROM SERVICE.dbo.configuration WHERE ConfigOption = 'TEST1' "')
    IF "%%a"=="Y" (
        Echo WOHOOOO
        PAUSE
    ) Else (
        ECHO NOOOOOO
        PAUSE
    )
)

我没有设法找到一个允许我从sql查询中为变量设置值的解决方案。相反，我已将结果输出到文件并从那里读取结果，然后删除该文件。这是代码：

@ECHO off    

echo _________________________________________________________

Echo The following inputs are required:
Echo    [1] Myserver


echo ---------------------------------------------------------
CD %~dp0

SET /p DBSERVER="Enter [1]: "


:: Get Configuration Type
sqlcmd -S %DBServer% -E  -i test.sql -b -v TYPE="CFIGTYPE" -h -1 >result.txt
set /p CFIGTYPE=<result.txt
call :Trimspaces CFIGTYPE %CFIGTYPE%
del "result.txt"


:: ------------------------------------------------ FUNCTIONS--------------------------------------------------------------------------------------------------------------
:trimSpaces2 retval string -- trims spaces around string and assigns result to variable
::                         -- retvar [out] variable name to store the result in
::                         -- string [in]  string to trim, must not be in quotes
for /f "tokens=1*" %%A in ("%*") do set "%%A=%%B"
EXIT /b

:trimSpaces varref -- trims spaces around string variable
::                 -- varref [in,out] - variable to be trimmed
call call:trimSpaces2 %~1 %%%~1%%
EXIT /b

由于输出文件将包含空，我已经包含了一个取自的函数 https://www.dostips.com/DtTipsStringOperations.php

这会在读取文件时消除空白区域。

我有一个额外的test.sql，其中包含以下代码：

SET NOCOUNT ON;
select configvalue FROM Service.dbo.Configuration WHERE ConfigOption = '$(type)'

SQLCMD具有1个返回值
