students choose to take several courses (100,200) at the same time, and some students choose only one course (300,400,500 ). If you are a student of multiple courses, You must select a course as your major. The major is flag, which is written into Y. Students who only select one course, whose major is flag is N (in fact, if I write Y, there will be no troubles below. For example, please include more ).Now we need to query the table according to the following two conditions:The person who takes

returns the ID of the course. Returns the ID of the selected primary course.The simple idea is to execute two different SQL statements for query.Condition 1 -- Condition 1: only students who have selected one course Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/-->SELECT std_id, MAX(class_id) AS main_classFROM StudentclassGROUP BY std_idHAVING COUNT(*) = 1;Execution result 1 Code highlighting produced by Actipro Code
