Hi Daniel,
Do you have a complete, minimal example? This needs a JIRA ticket
because it should work and I think details are going to matter.
"SELECT *" -- if there are no other SELECT level clauses (e.g. LIMIT) is
a no-op as a projection.
Maybe try with named variables.

Hi,
I’m trying to create a CONSTRUCT query using the Jena query builder and I
couldn’t figure out how to correctly add a subquery. I’ve tried to create code
similar to the following but in the end the expected “Select *” clause is
missing, only the where parts are present.
constructBuilder
.addConstruct(construct-clauses)
.addWhere(
whereBuilder
.addSubquery(
SelectBuilder
.addVar(“*”)
.addWhere(sub-where)
)
.addWhere(outer-where)
)
What I’m trying to get is
CONSTRUCT {
construct-clauses
}
WHERE {
SELECT * WHERE { sub-where}
outer-where
}
But what I’m really getting is
CONSTRUCT {
construct-clauses
}
WHERE {
WHERE { sub-where}
outer-where
}
The “Select *” is missing. Am I doing something wrong with my query builder
usage?
Any help is appreciated! Thanks in advance.
Daniel
