请高手回答:
1) I build a table on my database, the table's structure is people(int ID, string Name, string Address), Now I want to give ID a default value, the value is (表中最后一条记录的ID+1), my purpose is that everytime I insert a new record to the people table, I don't need to specify ID's value, the database system can automatically give me a unique value for ID.
2) If I just want to get the last record in a table(only one record), how to implement this with java.
For the first question, I think it's very easy for a database expert. The second question is not difficult too. But I just don't know, please help.
