Sphinx query column attribute problem?

source tags
{
    type                            = mysql
    sql_host                        = lo开发者_StackOverflowcalhost
    sql_user                        = abc
    sql_pass                        = 123456
    sql_db                          = company
    sql_sock                        =  /var/lib/mysql/mysql.sock
    sql_port                        = 3306

     sql_query_pre = SET NAMES utf8
     sql_query_range        = SELECT 1,max(id) FROM companies

sql_query                       = \
        SELECT a1,a2,a3,a4.....................,a64 FROM companies;
;

}

IN my query more 32 columns is there . in my linux server i am getting error more then 32 columns not available. How can i extend this columns size.

maybe you can concatenate some of your text data so it's presented as single column to sphinx?

change

SELECT a1,a2,a3,a4.....................,a64 FROM companies

into

SELECT concat(a1,a2,a3,a17,a62,a63,a64),a4..........a60 FROM companies
