Andy,
just to double-check: GROUP_CONCAT is supposed to take potentially
multiple expressions as arguments, but ARQ seems to be incomplete here?
Example?
CONCAT != GROUP_CONCAT
'GROUP_CONCAT' '(' 'DISTINCT'? Expression ( ';' 'SEPARATOR' '=' String
)? ')'
So no, exactly one expression and at most one separator.
Also, could you please make AggGroupConcat/Distinct.getSeparator()
public? I need this for the ARQ->SPIN RDF syntax conversion.
Done - you get back the separator as seen (so it may be null), not the
effective separator (defaults to space).
Thanks
