Hello Monks,

I'm having some trouble building an SQL statement from a
web form. I'm using Class::DBI's set_sql method to create and new method
that changes everytime through a loop. 
my $tables = [ qw/ starting_point_topics related_topics other_topics /
+ ];
my $results = {};
foreach my $table (@{$tables}) {

    my $query = qq{ SELECT res.* FROM res,$table,topics WHERE $query_t
+emp ORDER BY `rank` DESC };
    Library::Data::Res->set_sql(full_text => $query);
    $results->{$table} = Library::Data::Res->search_full_text;
}

A full SQL statement would look like this: 
 SELECT 
    res.* 
FROM 
    res,starting_point_topics,topics 
WHERE
    ((starting_point_topics.res = res.id)
AND
    (starting_point_topics.topic = topics.id)
AND
    (topics.name LIKE '%'))

The starting_point_topics would change as it loops and WHERE statement will change also but this is the one i'm testing right now. The error i'm getting is: 
search_full_text() already exists at /data/web/perl/lib/Library/Result
+s.pm line 95
                                 ORDER BY `rank` DESC SELECT res.* FRO
+M res,related_topics,topics WHERE
                                        ((starting_point_topics.res = 
+res.id)
                                        AND
                                        (starting_point_topics.topic =
+ topics.id)
                                        AND
                                        (topics.name LIKE '%'))
                                 AND
                                        ((related_topics.res = res.id)
                                        AND
                                        (related_topics.topic = topics
+.id)
                                        AND
                                        (topics.name LIKE '%'))

I 'm not sure why the table names in the where statement are not changing.
