But when i run this the whole table gets copied from register to login table...When i click accept only that particular users details must be moved.... Id must be fetched of that particular user... How to do that. Please someone help me fix this... Thanks in advance....

Answer 1

您应该在SQL语句中添加WHERE子句：

INSERT INTO LOGIN (id,FirstName,LastName,Gender, ...)
SELECT * FROM REGISTER WHERE ID=?

然后将id参数绑定到PreparedStatement：

PreparedStatement ps=conn.prepareStatement( ... );
ps.setInt(1, id);
ps.executeUpdate();

这样您就可以限制SELECT只返回您感兴趣的行并将其输入INSERT。
