问题 单项选择题

关于通配符的使用,下列说法中不正确的是( )。

B.使用通配符搜索星号、问号时,需要将搜索的符号放在方括号内

C.在一个“日期”字段下面的“准则”单元中使用表达式:Like“6/*/98”,系统会报错“日期类型不支持*等通配符”

D.在文本的表达式中可使用通配符,例如,可以在一个“姓”字段下面的“准则”单元中输入表达式:“M*s”,查找姓为 Morrris、Masters和Miller Peters等的记录

答案

参考答案:C

解析: 本题考查通配符的知识。通配符一般作为其他字符的占位符,其中包括星号(*)、问号()、方括号([])、叹号(!)、减号(-)和数字号码(#)。其中最常用的问号()表示所在的位置可以是任何一个字符,星号(*)表示所在的位置可以是任何多个字符。使用通配符搜索这些代表通配符的符号时,需要将搜索的符号放在方括号内。无论是文本型还是日期型字段都可以使用通配符。
