针对学生表Student(Sno,Sname, Ssex,Sage,Sdept)。要检索学生表中年龄在17至25岁之间(包括17和25)的学生的姓名及年龄,SQL语句正确的是( )。
A: Select * From Student Where Sage between 17 and 25
B: Select Sname, Sage From Student Where Sage between 17 and 25
C: Select Sname, Sage From Student Where Sage >= 17 and Sage<= 25
D: Select Sname, Sage From Student Where Sage >= 17 or Sage<= 25
A: Select * From Student Where Sage between 17 and 25
B: Select Sname, Sage From Student Where Sage between 17 and 25
C: Select Sname, Sage From Student Where Sage >= 17 and Sage<= 25
D: Select Sname, Sage From Student Where Sage >= 17 or Sage<= 25
举一反三
- 针对学生表Student(Sno,Sname, Ssex,Sage,Sdept)。要检索学生表中年龄在17至25岁之间(包括17和25)的学生的姓名及年龄,SQL语句正确的是( )。 A: Select * From Student Where Sage between 17 and 25 B: Select Sname, Sage From Student Where Sage between 17 and 25 C: Select Sname, Sage From Student Where Sage >= 17 and Sage<= 25 D: Select Sname, Sage From Student Where Sage >= 17 or Sage<= 25
- 【多选题】针对学生表Student(Sno,Sname, Ssex,Sage,Sdept),其中sno为学号,sname为姓名,ssex为性别,sage为年龄,sdept为系别。要检索学生表中年龄在17至25岁之间(包括16和30)的学生的姓名及年龄,SQL语句正确的是()。 A. Select * From Student Where Sage between 16 and 30 B. Select Sname, Sage From Student Where Sage between 16 and 30 C. Select Sname, Sage From Student Where Sage >= 16and Sage<= 30 D. Select Sname, Sage From Student Where Sage >= 16 or Sage<= 30
- 针对学生表Student(Sno,Sname, Ssex,Sage,Sdept),其中sno为学号,sname为姓名,ssex为性别,sage为年龄,sdept为系别。要检索学生表中年龄在17至25岁之间(包括16和30)的学生的姓名及年龄,SQL语句正确的是( )。 A: Select Sname, Sage From Student Where Sage between 16 and 30; B: Select Sname, Sage From Student Where Sage >= 16and Sage<= 30; C: Select * From Student Where Sage between 16 and 30; D: Select Sname, Sage From Student Where Sage >= 16 or Sage<= 30;
- 在所有学生中查询比计算机系学生平均年龄大的学生姓名,可以使用的查询语句是: A: SELECT Sname FROM Student WHERE Sage > ( SELECT AVG(Sage) FROM Student ); WHERE Sdept = 'CS' B: SELECT Sname FROM Student WHERE Sage > AVG( SELECT Sage FROM Student WHERE Sdept = 'CS' ); C: SELECT Sname FROM Student WHERE Sage > ( SELECT AVG(Sage) FROM Student WHERE Sdept = 'CS' ); D: SELECT Sname FROM Student WHERE AVG(Sage) > ( SELECT Sage FROM Student WHERE Sdept = 'CS' );
- 现要利用Student(sno, sname, ssex, sage, sdept)表查询年龄最小的学生的姓名和年龄。下列实现此功能的查询语句正确的是( )。 A: SELECT sname, Min( sage )from student B: SELECT sname ,sage from student where sage=Min( sage ) C: SELECT TOP 1 Sname , Sage From student D: SELECT TOP 1 sname , sage from student order by sage
