现要利用Student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中，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
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
举一反三
- 现要利用Student表查询年龄最小的学生姓名和年龄。下列实现此功能的查询语句中，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
- 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
- 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' );
- 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
- 在所有学生中查询比计算机系所有学生年龄都要大的学生姓名,正确的查询语句是___________________。 A: SELECT Sname FROM Student WHERE Sage > ( SELECT MAX(Sage) FROM Student WHERE Sdept = 'CS'); B: SELECT Sname FROM Student WHERE Sage > ALL ( SELECT Sage FROM Student WHERE Sdept = 'CS'); C: SELECT Sname FROM Student S1 WHERE EXISTS ( SELECT Sage FROM Student S2 WHERE Sdept = 'CS' AND S1.Sage > S2.Sage); D: SELECT Sname FROM Student S1 WHERE NOT EXISTS ( SELECT * FROM Student S2 WHERE Sdept = 'CS' AND S1.Sage <= S2.Sage);
