Sphinx setup

Hehe, don't laugh at me just trying to set up the Sphinx on my local WAMP, I haven't done that before, so I'm probably doing something stupid.

This is my sphinx.conf file:

source code
{
    type = mysql
    sql_host = localhost
    sql_user = root
    sql_pass =
    sql_db = ****
    sql_port = 3306
    sql_query = SELECT id, language_id, category_id, title, description, UNIX_TIMESTAMP(time_posted) AS time_posted FROM codes
    sql_attr_uint = language_id
    sql_attr_uint = category_id
    sql_attr_timestamp = time_posted
    sql_query_info = SELECT id FROM codes WHERE id=$id
}

index code
{
    source = code
    path = C:/Program Files/Wampserver 2/sphinx/var/data/sphinx/code
    morphology = stem_en
    min_word_len = 3
    min_prefix_len = 0
}

searchd
{
    port = 3312
    log = C:/Program Files/Wampserver 2/sphinx/var/log/searchd/searchd.log
    query_log = C:/Program Files/Wampserver 2/sphinx/var/log/searchd/query.log
    pid_file = C:/Program Files/Wampserver 2/sphinx/var/log/searchd/searchd.pid
}

      

        
        
        
      

    

When I try to index, I get this error:

ERROR: index 'code': column number 1 has no name.

      

        
        
        
      

    

What could be causing this problem? Thank.
