I try to do:
SELECT DISTINCT ?genotypingstudy_id_gs ?germplasm_name WHERE {
FILTER (?genotypingstudy_id_gs = "^.*$").
?genotypingstudy_id_genotypingstudy
vocab:genotypingstudy_id_genotypingstudy ?genotypingstudy_id_gs.
?genotypingstudy_id_genotypingstudy vocab:genotypingstudy_id_germplasm
?genotypingstudy_id_germplasm.
?genotypingstudy_id_germplasm vocab:germplasm_name ?germplasm_name.
}
and it doesn't work :-(

I guess you just have to write
FILTER ( ?whateverpropertytheprimarykeyismappedinto = yourvaluehere )
or maybe I didn't understand well what you're after.

Hi,
I have a D2RQ mapping file annotated with ontological concepts. I
use this mapping file to start a D2R-Server and I create SPARQL
queries to interrogate my database.
I have a problem to create my SPARQL queries and more precisely I
have a problem to deal with primary key values.
When I filter the value of an attribut, I use the FILTER option of
SPARQL. But I can't use this FILTER option to filter a primary key
value.
*_Example:
_*_Query with a filter option_
SELECT DISTINCT ?genotypingstudy_id_gs ?germplasm_name WHERE {
FILTER regex(?genotypingstudy_id_gs,"^.*$").
?genotypingstudy_id_genotypingstudy
vocab:genotypingstudy_id_genotypingstudy ?genotypingstudy_id_gs.
?genotypingstudy_id_genotypingstudy
vocab:genotypingstudy_id_germplasm ?genotypingstudy_id_germplasm.
?genotypingstudy_id_germplasm vocab:germplasm_name ?germplasm_name.
}
_SQL model_
genotypingstudy(_id_genotypingstudy,_ #id_germplasm)
germplasm(_id_germplasm_, name)
Do you have any idea how to filter value of a primary key into a
SPARQL query?
Regards
