  • 第1题:

    运算结果是字符串“home”的表达式是( )。A.LEFT(”myhome”,4)B.RIGHT(”hometown”,4)SX

    运算结果是字符串“home”的表达式是( )。

    A.LEFT(”myhome”,4)

    B.RIGHT(”hometown”,4)

    C.SUBSTR(”myhometown”,4,4)

    D.SUBSTR(”myhometown”,3,4)


    正确答案:D
    D。【解析】取子串的函数有下列三种格式:①LEFT从指定表达式值的左端取一个指定长度的子串作为函数值。②RIGHT从指定表达式值的右端取一个指定长度的子串作为函数值。③SUBSTR从指定表达式值的指定起始位置取指定长度的子串作为函数值。在SUBSTR函数中,若缺省第三个自变量<长度>,则函数从指定位置一直取到最后一个字符。从以上三个函数的功能得知,选项A的结果是“my—h0”,选项8的结果是“town”,选项C的结果是“omet”,选项D的结果是“home”。
