    CONCAT_WS(' ', es.Student_FName, es.Student_LName) AS Full_Name, 
    sa.Attendance_Date , 
    sa.Attendance_Status 
    FROM student_attendance sa 
    INNER JOIN courses c 
    ON c.Course_Id = sa.Course_Id 
    INNER JOIN campus ca 
    ON ca.Campus_Id = c.Campus_Id 
    INNER JOIN students es 
    ON es.Student_Id = sa.Student_Id 
    WHERE sa.Course_Id = 1 
    ORDER BY sa.Attendance_Date DESC;

尝试这样

SET @sql = NULL; 
SELECT 
    GROUP_CONCAT(DISTINCT 
    CONCAT(
    'MAX(IF(a.attendance_status = ''', 
     attendance_status, 
     ''', IF(a.attendance_status = "1","P","X"), NULL)) AS "', 
     attendance_date,'"' 
    ) 
    ) INTO @sql 
FROM student_attendance; 


SET @sql = CONCAT('SELECT a.Student_ID,a.student_name,', @sql, ' 
       FROM student_attendance a 
       LEFT JOIN student_attendance AS b 
       ON a.Student_ID=b.Student_ID GROUP BY a.Student_ID,b.Student_ID'); 

PREPARE stmt FROM @sql; 
EXECUTE stmt; 
DEALLOCATE PREPARE stmt;
