Cross tabbing in SELECT statement??

Question

Hi,
The following SQL statement:
SELECT
T.LASTFIRST, C.COURSE_NAME, CC.COURSE_NUMBER, CC.SECTION_NUMBER, CC.EXPRESSION, ST.GENDER, COUNT(CC.STUDENTID) STUDENTCOUNT
FROM TEACHERS T
JOIN CC
ON CC.TEACHERID = T.DCID
JOIN COURSES C
ON C.COURSE_NUMBER=CC.COURSE_NUMBER
JOIN STUDENTS ST
ON CC.STUDENTID=ST.ID
WHERE CC.SCHOOLID = 100 AND TERMID>=1900
GROUP BY T.LASTFIRST, C.COURSE_NAME, CC.COURSE_NUMBER, CC.SECTION_NUMBER, CC.EXPRESSION, ST.GENDER
ORDER BY T.LASTFIRST, CC.COURSE_NUMBER, CC.SECTION_NUMBER, CC.EXPRESSION, ST.GENDER
returns the following dataset:
Abram, Michael     U.S. History     SOC1000     2     1(A)     F     7
Abram, Michael     U.S. History     SOC1000     2     1(A)     M     12
Is there a way to make the gender count for each sex show up as an individual column in the SELECT statement so that their is only ONE row returned per Course Number with column headings like FEMALECOUNT and MALECOUNT??
I've tried using a nested select count statement inside the original SELECT statement but with no luck.

Won't work for the OP's requirement. As i specified in my post, if you keep the GENDER column you'll continue to get 2 rows.
