现有学生关系表S(sno,sname,ssex,sage),查找比所有"张三"年龄大的男生信息,下列选项中正确的SQL语句是________。
A: select * fromSwhere ssex='男' and sage>;SOME(select sage from S where sname='张三);
B: select * fromSwhere ssex='男' and sage>;ALL(select sage from S where sname='张三);
C: select * fromSwhere ssex='男' and sage>;(select max(sage) from S where sname='张三);
D: select * fromSwhere ssex='男' and sage>;(select min(sage) from S where sname='张三);
A: select * fromSwhere ssex='男' and sage>;SOME(select sage from S where sname='张三);
B: select * fromSwhere ssex='男' and sage>;ALL(select sage from S where sname='张三);
C: select * fromSwhere ssex='男' and sage>;(select max(sage) from S where sname='张三);
D: select * fromSwhere ssex='男' and sage>;(select min(sage) from S where sname='张三);
举一反三
- 要在student(sno,sname,ssex,sage,sdept)表中,查询全体女生的姓名、年龄,以下正确的查询语句是( )。 A: select * from student where ssex='女' B: select 姓名, 年龄 from student where 性别 ='女' C: select sname , sage from student where ssex='女’ D: select sname 姓名, sage 年龄 from student where ssex='女'
- 从Student表检索年龄小于21岁的男学生信息,最规范的SQL语句是( )。 A: Select * From Student Where Ssex='男' Or Sage<'21' B: Select * From Student Where Ssex='男' Or Sage<21 C: Select * From Student Where Ssex=男 And Sage<'21' D: Select * From Student Where Ssex='男' And Sage<21
- 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
- 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
