第5题:

在学生表中查找没有选课的学生,下列语句正确的是( )。

A.SELECT*FROM 学生 WHERE EXISTS; (SELECT*FROM 选课 WHERE学生号=学生.学生号)

B.SELECT*FROM 学生 WHERE NOT EXISTS; (SELECT*FROM 选课 WHERE 学生号=学生.学生号)

C.SELECT*FROM 学生 WHERE EXISTS; (SELECT*FROM 选课 WHERE 学生号=学生号)

D. SELECT*FROM 学生 WHERE NOT EXISTS; (SELECT*FROM 选课 WHERE 学生号=学生号)


正确答案:B
解析:本题是嵌套循环查循,在外层中使用了谓词EXISTS。依据题意,在子查询中有结果返回,应该用EXISTS谓词。内层查询引用了外层查询的表,所以在WHERE短语的学生号中使用关系名,即学生.学生号。

第6题:

有SQL语句: SELECT DISTINCT系号FROM教师WHERE工资>=; ALL(SELECT工资FROM教师WHERE系号="02") 与如上语句等价的SQL语句是

A.SELECT DISTINCT系号FROM教师WHERE工资>=; (SELECT MAX(工资)FROM教师WHERE系号="02")

B.SELECT DISTINCT系号FROM教师WHERE工资>=; (SELECT MIN(工资)FROM教师WHERE系号="02")

C.SELECT DISTINCT系号FROM教师WHERE工资>=; ANY(SELECT工资FROM教师WHERE系号="02")

D.SELECT DISTINCT系号FROM教师WHERE工资>=; SOME(SELECT工资FROM教师WHERE系号="02")


正确答案:A
解析:题干中的SQL语句的功能是:查询那些工资比02系工资都高的教师所在的系号,四个选项中只有选项A中的查询条件与此等价,用(SELECT MAX(工资) FROM…WHERE…)实现选择出最高工资,故选项A为正确答案。选项B的查询条件表示工资大于02系中工资最低的教师的工资,选项C和D中的ANY和SOME是同义词,表示查询出只要比02系中某一个教师工资高的记录即可。
