第10题
已知一个关系数据库的模式如下:market(mno,mname,city)、item(ino,iname, type,color)、sales(mno,ino,price),其中,market表示商场,它的各属性依次为商场号、商场名和所在城市;item表示商品,它的各属性依次为商品号、商品名、商品类别和颜色; sales表示销售,它的各属性依次为商场号、商品号和售价。
查询长沙每个商场都销售,且售价均超过3000元的商品的商品号和商品名的SQL语句为:
SELECT ino, iname FROM item
WHERE (24)
(SELECT* FROM market
WHERE (25) AND NOT EXISTS
(SELECT*FROM sales
WHERE (26) AND price>3000))
查询在不同的商场中最高售价和最低售价之差超过100元的商品的商品号、其最高售价和最低售价的SQL语句为:
SELECT ino, MAX(price), MIN(price)FROM sales
(27) HAVING MAX(price)-MIN(price)>100
A.EXISTS
B.NOTEXISTS
C.IN
D.NOTIN
