    设系统日期为2001 年 12月 31 日， 下列表达式的值是【 】。 VAL(SUBSTR("1999",3)+RIGHT(STR(YEAR(DATE()))，2))+17


    正确答案：9918.00 或 9918
    DATE()：返回当前系统日期YEAR()；从指定的日期表达式或日期时间表达式中返回年份STR(数值表达式＞)[，长度＞[，小数位数＞]])：将数值表达式＞的值转换成字符串，转换时根据需要自动进行四舍五入。RIGHT(字符表达式＞，长度＞)：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。SUBSTR(字符表达式＞，起始位置＞[，长度＞])从指定表达式的指定起始位置取指定长度的子串作为函数值。VAL(字符表达式＞[，长度＞[，小数位数＞]])：将数字符号(包括正负号、小数点)组成的字符型数据转换成相应的数值型数据。题面VAL(SUBSTR("1999",3)+RIGHT(STR(YEAR(DATE()))，2)+17=VAL(99+RIGHT(STR("2001")，2))+17=VAL("99"+"01")+17=9901+17=9918。
