Some points you could check:

1. :scriptnames shows plugin \\sqlcomplete.vim

But the link you provided points to .../vim/runtime/ autoload /sqlcomplete.vim, there is no .../vim/runtime/ plugin /sqlcomplete.vim, and the version at vim.org also doesn't contains a /plugin file:

install details
Copy sqlcomplete.vim to:
.vim/autoload/sqlcomplete.vim (Unix)
vimfiles\autoload\sqlcomplete.vim (Windows)

For documentation:
:h sql.txt 

Maybe you have installed it incorrectly.

2. The file on your link has version 12 at its header, while the latest version is 15. Try updating to the latest version

3. Note that this plugin does not define the SQLSetType command.

You could check that by simple searching the file the on link. And on its header:

" Vim OMNI completion script for SQL
" Language: SQL
" Maintainer: David Fishburn <dfishburn dot vim at gmail dot com>
" Version: 15.0
" Last Change: 2013 May 13
" Homepage: http://www.vim.org/scripts/script.php?script_id=1572
" Usage: For detailed help
" ":help sql.txt"
" or ":help ft-sql-omni"
" or read $VIMRUNTIME/doc/sql.txt

Following :help sql.txt :

2.1 SQLSetType                  *sqlsettype* *SQLSetType*
--------------
For the people that work with many different databases, it is nice to be
able to flip between the various vendors rules (indent, syntax) on a per
buffer basis, at any time.  The ftplugin/sql.vim file defines this function: >
    SQLSetType

And scriptnames is not listing ftplugin/sql.vim
