public static void main(String[] args){
DBManager db = new DBManager();
Book bookInfo = new Book("code","codename","cidsys","cnum","booknum",
"usernum","bookname","edition",100,"author","frame","ckb",
"8 16 2000 11:50AM",1,1,100,2,200,"press","ksname");
db.saveBook(bookInfo);
}
另外：关于smalldatetime转换，要转换的字符串都可以是那些格式呢？我自己试了试，好像只有"8 16 2000 11:50AM"可以有其他方法吗？
