i am new to database. i need help in solving the OLAP query syntax problem below;

1. find the number of publication for different types of publication (journal, conference, book) for each faculty in the university, for the last five years.

below is my solution but not sure is right

SELECT facultyNo,publicationType,yearmonth,COUNT(*) AS pubcount
FROM faculty,publishedpapers,publicationlist
WHERE faculty.facultyNo = publicationlist.facultyNo
AND publishedpapers.publicationnNo = publicationtlist.publicationNo
AND publishedpapers.publicationtype = ('journal','conference','book')
AND publicationlist.yearmonth BETWEEN ('1-JAN-2005' AND '31-DEC-2009')
GROUP BY ROLLUP(facultyNo,publicationtype,yearmonth,pubcount);
