问题 单项选择题

在Visual FoxPro中以下叙述正确的是______。

A.利用视图可以修改数据
B.利用查询可以修改数据
C.查询和视图具有相同的作用
D.视图可以定义输出去向

答案

参考答案:A

解析: 视图是操作表的一种手段,通过视图可以查询表,也可以更新表,所以利用视图可以修改数据,A选项叙述正确;而查询是从指定的表或视图中提取满足条件的记录,然后按照想得到的输出类型定向输出查询结果,所以查询不能修改数据,而查询可以定义输出去向,B、D选项叙述不正确;很明显,查询和视图具有不同的作用,C选项叙述不正确。

     Jan Mela isn't like most kids. Two years ago, he lost an arm and a leg. But that didn't stop him.

     On Saturday, the 15-year-old boy from Poland (波兰) walked to the North Pole (北极) without any help.

     "If I can do it, other people can do great things, too,"  Mela said before he went.

     Polish newspapers said Mela is the youngest person and the first handicapped (残疾的) person to walk

to the North Pole.

     How did Mela lose an arm and a leg? He had an electrical (电的) accident. Now, he walks with the help of

a 62,000-yuan man-made leg.

     After the accident, Mela felt sad for himself. But he didn't lose hope. One day, he met Marek Kaminski,  a

Polish explorer. Eight years ago, Kaminski went to the North Pole and the South Pole in the same year. Mela

wanted to see the North Pole, too. So Mela asked Kaminski if they could go together next time.Kaminski said

yes!

     It took Mela 21 days to get to the North Pole. The last three or four days were really hard because of bad

weather. But Mela kept going.

     "I didn't think we would make it," he said, "Then, things got better."
