Hi All, I am using testlink tool with mysql ( teamst.org/phpBB2/viewtopic.php?t=1938 ). I have found that this query takes 54 secs to fetch data..which is not acceptable.. I am not conversant with mysql tuning... SELECT NHB.parent_id AS testsuite_id, NHA.parent_id AS tc_id, NHB.node_order AS z, T.tcversion_id AS tcversion_id, T.id AS feature_id, TCV.active, E.id AS exec_id, E.tcversion_id AS executed, E.testplan_id AS exec_on_tplan, UA.user_id,UA.type, UA.status, UA.assigner_id, COALESCE(E.status,'n') AS exec_status FROM nodes_hierarchy NHA JOIN nodes_hierarchy NHB ON NHA.parent_id = NHB.id JOIN testplan_tcversions T ON NHA.id = T.tcversion_id JOIN tcversions TCV ON NHA.id = TCV.id JOIN executions E ON (NHA.id = E.tcversion_id AND E.testplan_id=T.testplan_id AND E.build_id=21 ) LEFT OUTER JOIN user_assignments UA ON UA.feature_id = T.id WHERE T.testplan_id=30397 AND (UA.type=1 OR UA.type IS NULL) AND E.status='p' AND E.id IN ( SELECT MAX(id) FROM executions WHERE testplan_id=30397 GROUP BY tcversion_id,testplan_id ) ORDER BY testsuite_id,NHB.node_order,tc_id,E.id ASC; Any help to bring down the sql execution time would be highly appreciated.
