Mysql 有数据更新,无则插入

项目中须要去更新数据的版本号.

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()
