I want to script a query to a SphinxQL server (via the MySQL 4.1 transport protocol). I can query the server properly via the command line mysql client, but am unable to via luasql. Can someone point me to a working example of how to use luasql to query a sphinxql server?

The following works:
$ mysql -P9306 --protocol=tcp --prompt='sphinxQL> '

The following does not:
$ lua5.1
Lua 5.1.5  Copyright (C) 1994-2012 Lua.org, PUC-Rio
> mysql = require "luasql.mysql"
> env  = mysql.mysql()
> = env:connect('localhost','9306')
nil    LuaSQL: error connecting to database. MySQL: Access denied for user '9306'@'localhost' (using password: NO)
> return  env:connect('user','pass','localhost','9306')
nil    LuaSQL: error connecting to database. MySQL: Can't connect to MySQL server on '9306' (22)

thanks!
