  • 第1题:

    查询选修了课程号为“MATHS”的学生的姓名和年龄,若用下列SQL的SELECT语句表达时,错误的是( )。

    A) SELECT SNAME,AGE FROM S WHERE S. S# =(SELECT SC. S# FROM SC WHERE

    c.c# ='MATHS ')

    B ) SELECT SNAME, AGE FROM S WHERE S. S# =(SELECT SC. S# FROM SC WHERE

    SC. C# =' MATHS ')

    C) SELECT SNAME, AGE FROM S, SC WHERE S. S# =SC. S# AND SC. C# ='MATHS'

    ORDER BY S. S#

    D)SELECT SNAME, AGE FROM S, SC WHERE S. S# =SC. S# AND SC. C# ='MATHS'


    正确答案:A
    有两种方式进行题干所述的查询:连接查询方式和带嵌套的简单查询方式。连接查询方式是在表‘S和SC中按照S.S#=SC.S#和SC.C#=‘MATHS’的条件查找。带嵌套的简单查询方式是先只查询S表,在WHERE子句中限定“选修了课程号为‘MATHS’”…。WHERE子句中又带简单查询的SELECT语句,为SELECT SC.S#FROM SC WHERE SC.C#=‘MATHS’,即在SC表中按SC.C#=‘MATHS'的条件查找。

    A. Mike always puts his things away.

    B. Tom can mend the kite.

    C.Mike is not a careful boy.

    D. Mike's shoes are worn out


    正确答案:A
    29.A【解析】本题足问下面哪一个说法是错误的,Mike的屋子很不整洁,就是因为他不收拾自己的东西。选项A的意思是“他总是收拾自己的东西”,put…away是。把……收起来放好”的意思,可见A是错误的。

  • 第3题:

    查询所修课程成绩都大于等于85分的学生的学号和姓名,正确的命令是( )。

    A.SELECT学号,姓名FROM student s WHERE NOT EXISTS (SELECT*FROM score se WHERE SC.学号=s.学号码AND成绩<85)

    B.SELECT学号,姓名FROM student S WHERE NOT EXISTS (SELECT*FROM score sc WHERE SC.学号=s.学号码AND成绩>=85)

    C.SELECT学号,姓名FROM student s,score sc WHERE s.学号=sc.学号AND成绩>=85

    D.SELECT学号,姓名FROM student s,score sc WHERE S.学号=sc.学号AND ALL成绩>=85


    正确答案:B
    B。【解析】由题可得,所查询的成绩是大于等于85分的学生的学号和姓名,其中成绩和学号、姓名不在一个表内,所以要用嵌套查询。而其中的成绩是大于等于85分,所以答案选择B。

    D.SELECT s.学号,姓名,AVG(成绩)平均成绩FROM student s,score sc WHERE s.学号=sc.学号 GROUP BY s.学号HAVING COUNT(*)>=5ORDER BY 3 DESC


    正确答案:D
    解析:HAVING短语必须跟随GROUP BY使用,它用来限定分组必须满足 的条件,所以本题正确答案为D。

  • 第13题:

    阅读下列代码 public class Arrays{ public static void main(String[]args){ int[]a=new int[5]; for(int i=0;i<a. length; i=i+1){ a[i]=10+i; } for(int i=0; i<a. length; i=i+1){ System. out. println(a[i]); } String[]s={"Frank","Bob","Jim"}; for(int i=0; i<s. length; i=i+1){ System. out. println(s[i]); } S[2]="Mike"; System. out. println(s[2]); } } 代码运行结果正确的是

    C.10 11 12 13 14 Frank Bob Jim Mike

    D.11 12 13 14 15 Mike Jim Bob Frank


    正确答案:C
    解析:每一个for循环对整型数组a赋值时从“10+0”开始,直到“10+4”为止共5个数。第二个for循环直接将字符串数组内容依次打印出来,循环结束后对s[2]重新赋值为“Mike”,故再次打印s[2]时输出“Mike”。

    B


    SELECT学号,姓名FROM student s WHERE NOT EXISTS

    WHERE s.学号=sc.学号AND ALL成绩>=85


    正确答案: D
    解析:
    要查找所修课程成绩都大于等于85分的学生的学号和姓名,意思就是没有一门课程的成绩低于85分。B项表示没有一门课程的成绩高于85分,与题意相悖。C项表示只要有一门课程的成绩低于85就成立,D项中ALL用法错误。

  • 第23题:

    单选题
    学生表:S(学号,姓名,性别)和选课成绩表:SC(学号,课程号,成绩),用SQL语言检索选修课程在5门以上(含5门)的学生的学号、姓名和平均成绩,并按平均成绩降序排序,正确的命令是(  )。
    A

    SELECT S.学号,姓名,AVG(成绩)平均成绩 FROM S,SC;
    WHERE S.学号=SC.学号;
    GROUP BY S.学号,姓名 HAVING COUNT(*)>=5 ORDER BY 3 DESC

    B

    SELECT S.学号,姓名,AVG(成绩) FROM S,SC;
    WHERE S.学号=SC.学号 AND COUNT(*)>=5;

    C

    SELECT S.学号,姓名,AVG(成绩) 平均成绩 FROM S,SC;
    WHERE S.学号=SC.学号 AND COUNT(*)>=5;

    SELECT S.学号,姓名,平均成绩 FROM S,SC;
    WHERE S.学号=SC.学号;
    GROUP BY S.学号,姓名 HAVING COUNT(*)>=50RDER BY 平均成绩 DESC


    正确答案: C
    解析:
    题目要求查找选修课程在5门以上(含5门)的学生,则应该用HAVING COUNT(*)>=5进行限定。使用HAVING子句可以定义这些组所必须满足的条件以进行限定。GROUP BY将查询结果按指定列分成集合组。AVG可以计算对每个学生分组后的平均成绩,即AVG(成绩)。A项正确,ORDER BY 3 DESC指按查询结果中第三列数据降序排列,即ORDER BY平均成绩DESC。
