测验中分数在80到100之间的候选人需要面试,合适的查询语句的WHERE子句是( )。
A: WHERE siTestScore>=80? AND? siTestScore<=100
B: WHERE siTestScore>80? AND? siTestScore<100
C: WHERE siTestScore<=80? AND? siTestScore>=100
D: WHERE siTestScore<80? AND? siTestScore>100
A: WHERE siTestScore>=80? AND? siTestScore<=100
B: WHERE siTestScore>80? AND? siTestScore<100
C: WHERE siTestScore<=80? AND? siTestScore>=100
D: WHERE siTestScore<80? AND? siTestScore>100
举一反三
- 测验中分数在80到100之间的候选人需要面试,合适的查询语句的WHERE子句是( )。 A: WHERE siTestScore>=80? AND? siTestScore<=100 B: WHERE siTestScore>80? AND? siTestScore<100 C: WHERE siTestScore<=80? AND? siTestScore>=100 D: WHERE siTestScore<80? AND? siTestScore>100
- 查找成绩在70到80分之间的学生选课及得分情况。正确的SQL语句是( )。 A: SELECT * FROM 选课 WHERE 成绩>=70 AND 成绩<=80 B: SELECT * FROM 选课 WHERE 成绩≥70 AND 成绩≤80 C: SELECT * FROM 选课 WHERE 成绩>='70’ OR 成绩<='80’ D: SELECT * FROM 选课 WHERE 成绩>=70 OR 成绩<=80
- 若有“选课”表,其关系模式为:选课(学号,课程号,成绩),下列哪个语句可以实现查询所有成绩小于80或大于90的记录的功能? A: SELECT * FROM 选课 WHERE 成绩< 80 OR 成绩>90 B: SELECT * FROM 选课 WHERE 成绩 NOT BETWEEN 80 AND 90 C: SELECT * FROM 选课 WHERE NOT(成绩>= 80 AND 成绩<=90) D: SELECT * FROM 选课 WHERE 成绩>= 80 AND 成绩<=90
- 以下条件语句与“where 数量 not between 15 and 30”等价的是: A: where 数量 >= 15 and 数量 <=30 B: where 数量 <= 15 and 数量 >=30 C: where 数量 < 15 or 数量 >30 D: where 数量 > 15 or 数量 <30
- 从成绩信息表中查找成绩再80到90之间的学生信息,正确的语句是( )。 A: SELECT * FROM 成绩信息 WHERE 成绩 IS 80~90; B: SELECT * FROM 成绩信息 WHERE 成绩BETWEEN 80 AND 90; C: SELECT * FROM 成绩信息 WHERE 80<=成绩<=90; D: SELECT * FROM 成绩信息 WHERE 成绩>=80 AND 成绩<=90;
