Condition LIKE with or for autocomplete


#1

Hello!

I need some help. I am doing an auto complete that hast to find result
from
a mysql database of some people if the text written in the text box
matches
the name or last name. It works if i only want to find matches with the
name
or indepently the secon name but not with a or of both.
I have this

@inscritos = Inscrito.find(:all,
:conditions => [“LOWER(nombre) LIKE ?”,
‘%’ + params[:familiar][“0”].downcase + ‘%’ ],
:order => ‘apellido ASC’,
:limit => 8)

this works fine but then i want something like this

@inscritos = Inscrito.find(:all,
:conditions => [“LOWER(nombre) OR LOWER(apellido) LIKE ?”,
‘%’ + params[:familiar][“0”].downcase + ‘%’ ],
:order => ‘apellido ASC’,
:limit => 8)

Shouldn’t it be

@inscritos = Inscrito.find(:all,
:conditions => [“LOWER(nombre) LIKE ? OR LOWER(apellido) LIKE
?”,
‘%’ + params[:familiar][“0”].downcase + ‘%’ ],
‘%’ + params[:familiar][“0”].downcase + ‘%’ ],
:order => ‘apellido ASC’,
:limit => 8)

otherwise you are saying ‘LOWER(nombre) is true or LOWER(apellido) LIKE
blah’

Cheers

I would think that would work if you enclosed your arguments in
parens, e.g.

(LOWER(nombre) OR LOWER(apellido)) LIKE ?

or alternatively

LOWER(nombre) LIKE ? OR LOWER(apellido) LIKE ?

FWIW,

I made a concatenation of nombre apellido and then made the search that
worked great.
Thank for your help
