Mysql 有數據更新,無則插入

項目中需要去更新數據的版本號.

INSERT INTO Biz_CourseErrorBookDetail
            (CourseID,QuestionID,StudentID,ErrorCount,LastTime,CreateDTM)
             VALUES
            (#{emp.CourseID}, #{emp.QuestionID}, #{emp.StudentID}, 0, NOW(), NOW())
            ON DUPLICATE KEY UPDATE ErrorCount = ErrorCount + 1,LastTime = NOW(),UpdateDTM = NOW()
