Peter Eisentraut is right... The rewritten query I suggested is only derived from your original query and implicit data definitions (including constraints). I would like to point 2 things about that rewritten proposed query: - Column 'inserted' is likely missing in the 2nd subquery and in the global join condition; - Duplicity or even multiplicity of value s.name and/or p.name may result depending on the keys of tables (as implicitly mentioned by Peter Eisentraut).
