How do I get the field "count (t2.id_atend) TOTAL_ATENDIMENTO "and calculate the mean of it in PHP?
SELECT t3.desc_serv,
t3.nm_serv,
t1.nm_usu,
count(t2.id_atend) TOTAL_ATENDIMENTO
FROM usuarios t1
INNER JOIN historico_atendimentos t2 ON t1.id_usu = t2.id_usu
INNER JOIN servicos t3 ON t2.id_serv = t3.id_serv
WHERE t3.id_serv = 9 AND t2.dt_fim LIKE '%2013-10%'
GROUP BY t3.id_serv, t1.id_usu
output print:
