Answer 1

这个答案解决了

SELECT student.StudentID, student.Name,

IF ( ( SELECT DISTINCT 1 FROM attendance WHERE attendance.StudentID = student.StudentID AND date = '2015-09-07' ) = 1, 'Present', 'Absent' ) AS 2015-09-07,

IF ( ( SELECT DISTINCT 1 FROM attendance WHERE attendance.StudentID = student.StudentID AND date = '2015-09-14' ) = 1, 'Present', 'Absent' ) AS 2015-09-14,

student.WorkshopID FROM student
