我想使用存储过程从我的mysqli数据库访问OUT参数,并将其保存在php变量中,以便在网页上打印消息。
我的存储过程是:
DELIMITER $$
CREATE procedure insertUser (IN _name varchar(50), IN _username varchar(50), IN _password varchar(50), IN _email varchar(50), IN _cellNumber int(11), IN _estateName varchar(50), OUT _rply varchar(50))
BEGIN
DECLARE count1 int;
DECLARE count2 int;
DECLARE varEstateId int;
DECLARE _result varchar(50);
select COUNT(*) into count1 from users where username = _username;
select COUNT(*) into count2 from users where email = _email;
if (count1+count2 < 1)
THEN
insert into users (username , passkey , email) VALUES (_username ,_password,_email);
insert into estatedetails (estateName, estateOwnerUsername)
values (_estateName, _username);
SELECT estateId into varEstateId from estatedetails where estateOwnerUsername = _username;
insert into usersdetail (username, name, cell1, estateId, accountType)
VALUES (_username, _name, _cellNumber, varEstateId, 'owner');
set _result = 'inserted';
else
set _result = 'alreadyExist';
end IF;
set _rply = _result;
END$$
DELIMITER;
我调用存储过程的php端代码是:(不完整代码)
$db = new mysqli('localhost', 'root', '', 'estatelink');
$stmt=$db->prepare("CALL insertUser(?,?,?,?,?,?,?)");
$stmt->bind_param('ssssiss',$name, $username, $password, $email, $num, $estate_name, $rply);
$stmt->execute();
$result= $rply;
注意:我的查询正在成功执行完美插入数据。我唯一的问题是如何在这种情况下访问OUT参数$ rply。
先谢谢。

您不使用输出参数。您可以设置其值,如下所示:
set @_rply = 'foobar';
您可以使用它,如下所示:
$db->multi_query( "CALL insertUser($name,$username,$password,$email,$cellNumber,$estateName,@_rply);SELECT @_rply as _rply" );
$db->next_result(); // flush the null RS from the call
$rs=$db->store_result(); // get the RS containing the id
echo $rs->fetch_object()->_rply, "\n";
$rs->free();

您可以在过程中使用SELECT语句,并像典型查询一样获取结果
