[Bioperl-l] Question on seqfeature mapping

[Lajus Florian]

Never mind. It works much better if write: 
"Bio::Annotation::SimpleValue<=>Bio::SeqFeatureI instead.

The problem is if we also want to find by primary_tag:
my $query = Bio::DB::Query::BioQuery->new(
-datacollections => ["Bio::Annotation::SimpleValue<=>Bio::SeqFeatureI qv"],
-where => ["Bio::Annotation::SimpleValue::tagname = \'$tag\'","qv.value 
= \'$value\'","Bio::SeqFeatureI.primary_tag = ".$term_primary_key]);

The slot type_term_id is not mapped to column for table seqfeature
