Syntax highlighting for the MDX query language (OLAP).
If you don't have a preferred installation method, I recommend installing pathogen.vim, and then cloning the repo:
cd ~/.vim/bundle
git clone https://github.com/findango/vim-mdx.git
Or you can manually copy the files:
git clone https://github.com/findango/vim-mdx.git
cd vim-mdx
cp syntax/mdx.vim ~/.vim/syntax/
cp ftdetect/mdx.vim ~/.vim/ftdetect/
cp ftplugin/mdx.vim ~/.vim/ftplugin
On Windows, substitute ~/.vim/ with $HOME/vimfiles/ or $VIM/vimfiles/.
