Asumiendo que su fecha es una datetime real columna:
SELECT MONTH(date), YEAR(date), id_publisher, COUNT(*)
FROM raw_occurrence_record
GROUP BY MONTH(date), YEAR(date), id_publisher
Puede concatenar su mes y año así:
SELECT CONCAT(MONTH(date), '/', YEAR(date)) AS Month, id_publisher, COUNT(*)
FROM raw_occurrence_record
GROUP BY MONTH(date), YEAR(date), id_publisher
Para encontrar meses en los que no hay registros, necesitará una tabla de fechas. Si no puede crear uno, puede UNION ALL una tabla de calendario así:
SELECT a.year, a.month, b.id_publisher, COUNT(b.id_publisher) AS num
FROM
(SELECT 11 AS month, 2012 AS year
UNION ALL
SELECT 12, 2012
UNION ALL
SELECT 1, 2013
UNION ALL
SELECT 2, 2013) a
LEFT JOIN raw_occurence_record b
ON YEAR(b.date) = a.year AND MONTH(b.date) = a.month
GROUP BY a.year, a.month, b.id_publisher
