    D.SELECT DlSTINcT部门号FROM职工WHERE基本工资>=ALL (SELECT MIN(基本工资)FROM职工WHERE部 门号=”11”)


    正确答案:B
    B。【解析】在SQL语句中可以利用ANY、ALL等量词进行查询。基本格式为:<表达式><比较运算符>[ANYIALLISOME](子查询)其中,ANY(任意的)和SOME(一些)表示只要子查询中存在符合条件的行,结果就成立;而ALL(所有的)只有子查询中的所有行都符合条件,结果才成立。本题中要求检索有职工的基本工资大于或等于“ll”部门中任意一名职工的工资的部门号,等价于其他部门职工的基本工资有大于或等于“ll”部门中所有职工的工资,因此要使用ALL短语。选项C和D的属于语法错误,SQL不支持此类型查询。
