用T-SQL创建数据库总是出现：尝试打开或创建物理文件create file 遇到系统错误。试遍了网上的方法，D盘有操作权限，但是就是不行。麻烦大家帮我看看，球球了。代码如下create DATABASE student ON PRIMARY( Name = student_data, FILENAME ='D:\zhaoyingchao\data\student.mdf', SIZE = 10MB, MAXSIZE = UNLIMITED , FILEGROWTH =1 )LOG ON ( NAME = student_Log, FILENAME='D:\zhaoyingchao\data\student.ldf', SIZE = 3MB, MAXSIZE = UNLIMITED, FILEGROWTH = 10% )
