Answer 1

String sql="insert into custom (uid,nickname,gender,pwd,realname,career,address,email,tel,birth) values('"+uid+"',
'"+nickname+"','"+gender+"','"+pwd+"','"+realname+"','"+career+"','"+address+"','"+email+"','"+tel+"','"+birth+"')";
ResultSet rs=db.executeQuery(sql);oracle是用insert into的SQLSERVER呢?
