SQLCMD with 1 return value - batch-file

Question

I am trying to return a single value from a sqlcmd query used in a bat file.
It seems that i have some errors with the syntax used in my sqlcmd query. I am very new to coding in cmd, any guidance would help. I am using this query on a server.
#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
}
My code just closes after it reaches the sqlcmd portion.
Revised code in light of comments:
(does not solve problem)
#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
)
)

Answer 1

I didnt manage to find a solution that allows me to set a value to a variable from a sql query. Instead, i have output the results to a file and read the results from there and then delete the file. Here goes the code:
#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
Since the output file would contain empty i have included a function taken from
https://www.dostips.com/DtTipsStringOperations.php
That would eliminate the empty spaces when reading the file.
I have an extra test.sql which contains the following code:
SET NOCOUNT ON;
select configvalue FROM Service.dbo.Configuration WHERE ConfigOption = '$(type)'
