    C

    SELECT price FROM book WHERE book_name＝“数据库%”

    D

    SELECT price FROM book WHERE book_name LIKE“数据库%”


    正确答案： B
    解析： 谓词LIKE可以用来进行字符串匹配，其一般格式是LIKE‘<匹配串>’，匹配串可以是一个完整的字符串，也可以含有通配符%和_。%代表任意长度字符串，_代表任意单个字符。A选项*是查询表中所有属性的意思，但是格式不对。若LIKE后的匹配串中不含通配符，可以用“＝”代替LIKE，故C错误。

    答案：C
    解析：
    空格所在的主语是the same data,介词to后面的宾语为：economic analysis；在语义上，二者之间的关系理应为“……数据被用于……分析”。联系上下文可知，the same data指代前面提到的实验数据。因此本题所在句的大致意思是：几十年后，上述实验的数据用于/接受了计量经济学分析。符合句意的只有C选项。
