mysql 查询考试总人数，请我下我的错在哪里，代码如下

#参加考试的总人数#
SELECT COUNT (writtenExam)AS 考试总人数 FROM stuMarks

错误代码： 1630
FUNCTION studb.count does not exist. Check the 'Function Name Parsing and Resolution' section in the Reference Manual

SELECT COUNT(writtenExam) AS 考试总人数 FROM stuMarks
count后面多个空格，as 前面少个空格

select count(*) from stuMarks
