  • 第1题：

    给出在仓库“WHl”或“WH2”工作，且年龄小于40岁的职工号和姓名，正确的命令是（ ）。

    A)SELECT 职工号，姓名 FROM 职工：

    WHERE 年龄<40 AND 仓库号=”WH1”OR 仓库号=”WH2”

    B)SELECT职工号，姓名 FROM 职工；

    WHERE年龄<40 AND(仓库号=”WH1”AND 仓库号=”WH2”)

    C)SELECT职工号，姓名 FROM 职工；

    WHERE年龄<40 OR 工仓库号=”WH1”OR 仓库号=”WH2”

    D)SELECT职工号，姓名 FROM 职工：

    WHERE年龄<40 AND(仓库号=”WH1”OR 仓库号=”WH2”)


    正确答案：D
    依据题意，本查询应该有两个筛选条件，即“仓库=''WH1 ”OR仓库=“WH2”和“年龄<40”，并且这两个条件要同时满足，也就是说本题应先进行或运算，即先判断“仓库=WH1”OR仓库="WH2””，再将此结果与“年龄<40”的条件进行与运算，又因为与运算比或运算的优先级高，所以要将或运算用圆括号括起来。
