INNER JOIN dw_diag_obj T80 ON T142.diag_obj_id = T80.diag_obj_id
AND T80.school_code IN ( ‘bjzx’ )
AND T80.school_term_id IN ( ‘2111’ )
INNER JOIN dw_naire_number_answer_obj_avg T137 ON T80.diag_obj_id = T137.diag_obj_id
AND T80.school_code = T137.school_code
AND T80.school_term_id = T137.school_term_id
GROUP BY
T142.subject_id,
