We have a bunch of sql files with no extension on the file name. I'd like to open them as sql files for syntax highlighting, custom indentation depth, etc., but I don't want to have to rename the files to add the extension every time I want to edit them (and let's just say that they have to stay extensionless).

Is this possible?

Yes. This is described in :help section usr_06.txt on syntax highlighting.

You can turn syntax highlighting on and set the filetype this way:

:syntax enable
:set filetype=sql

Is there a way to put this in an rc file and load using -u at vim launch? In my tests it gets overridden by the file type extension's syntax highlighting and only works for files without associated syntax. – Daniel Beck Nov 28 '12 at 19:46

Are they in an identified location? All in one directory? If so, you can do:

autocmd BufRead,BufEnter /path/to/directory/* set ft=sql

Otherwise you'll have to write your own file detection routine.

In this case they are, and this works very nicely, thanks! – Dean Nov 28 '12 at 22:00
