Explain what you mean by "correlated subquery." Like I said in the original post, I need help to modify this exact query: SELECT qi,ri,(drl- (qi - :qi) ) as drl,MAX(score - ((ri - :ri) * :match)) AS scr FROM results_1 WHERE (qi - ri) = (:qi - :ri) AND (qi >= :qi) AND (ri >= :ri) AND (qi < :qi + 256) AND (ri < :ri + 256) AND (drl > qi - :qi) to make it such that I get the max of the above scr over :qi to bounds.upperQi and :ri to bounds.upperRi
