在Python中变量student和Student是同一个变量。()

select count（*） from student和select count（id） from student之间的区别是什么？ 这段代码的意思是创建一个Student对象，并保存到本地线程变量中（） 若对STUDENT表执行DELETE FROM STUDENT或DROP TABLE STUDENT命令，下列描述中正确的是（） You need to design a student registration database that contains several tables storing academic information. The STUDENTS table stores information about a student. The STUDENT_GRADES table stores information about the student's grades. Both of the tables have a column named STUDENT_ID. The STUDENT_ID column in the STUDENTS table is a primary key. You need to create a foreign key on the STUDENT_ID column of the STUDENT_GRADES table that points to the STUDENT_ID column of the STUDENTS table. Which statement creates the foreign key?（） student（） He is a student of great intelligence and diligence. _______,he is a top student in the class.　　 "SELECT Student.姓名,Scores.成绩 FROM Student INNER JOIN Scores ON Student.学号=Scores.学号"语句的意思是（） is no power like ______ powerof confidence, and there is no student as competitive as ______ student who trusts his own abilities “void point(student &s);”是某类中的一个成员函数声明，Student &s的含义为（?????
