您可以调用存储过程，该过程将执行插入操作，并在一次调用中将结果集从应用程序层返回到MysqL：
MysqL> call insert_user('bar');
+---------+----------+
| user_id | username |
+---------+----------+
| 1 | bar |
+---------+----------+
1 row in set (0.02 sec)
$sqlCmd = sprintf("call insert_user('%s')", ...);
drop table if exists users;
create table users
(
user_id int unsigned not null auto_increment primary key,
username varchar(32) unique not null
)
engine=innodb;
drop procedure if exists insert_user;
delimiter #
create procedure insert_user
(
in p_username varchar(32)
)
begin
declare v_user_id int unsigned default 0;
insert into users (username) values (p_username);
set v_user_id = last_insert_id();
-- do more stuff with v_user_id e.g. logs etc...
select * from users where user_id = v_user_id;
end#
delimiter ;
call insert_user('bar');
