'Month'::text) AS mes,
count(t2.fecha_analista) AS a,
count(t2.fecha_exp) AS r
FROM tb_analistas t1
JOIN tb_ingreso_siabc t2 ON t1.id_an = t2.analista
WHERE t1.id_an = param::double precision AND
date_part('year'::text, t2.fecha_analista) = periodo::double precision AND
t2.tipo_ccmm = 1
GROUP BY (to_char(t2.fecha_analista::timestamp with time zone,
'Month'::text))
