I have tried the following code in my batch file but it is not working
mysql\bin\mysqld.exe --defaults-file=mysql\bin\my.ini --standalone --console
Did you maybe just forget to specify the absolute path. This works fine for me.
set root=c:\xampp\
%root%mysql\bin\mysqld.exe --defaults-file=%root%mysql\bin\my.ini --standalone --console
pause
if its not,what is the errormessage you get calling your file
