I get 2014 Cannot execute queries while other unbuffered queries are active when doing exec with PDO
Databases

I am doing a PDO::exec command on multiple updates:


$MyPdo->setAttribute(PDO::MYSQL_ATTR_USE_BUFFERED_QUERY,true);
$MyPdo->exec("update t1 set f1=1;update t2 set f1=2");

I am doing it inside a transaction, and I keep getting:

How to avoid this PDO exception: Cannot execute queries while other unbuffered queries are active
Databases

I'd like to print a simple table in my page with 3 columns, building name, tags and architecture style. If I try to retrieve the list of building names and arch. styles there is no problem:


SELECT buildings.name, arch_styles.style_name
FROM buildings
INNER JOIN buildings_arch_styles
ON buildings.id = buildings_arch_styles.building_id
INNER JOIN arch_styles
ON arch_styles.id = buildings_arch_styles.arch_style_id
LIMIT 0, 10

My problem starts on retreaving the first 5 tags for every building of the query I've just wrote.

I know this has to be a simple fix and I partially understand why I am getting this error but don't know how to fix it. I've looked over the docs but can't find a solution other than using buffered queries option. I have tried that as well but it doesn't work.


The error is: PDO Cannot execute queries while other unbuffered queries are active


The error is coming from the line where I am building the $result array.


foreach($phones as $phone)
{
$stmt = db::getInstance()->prepare("CALL phones(:phone)");
$stmt->bindParam(':phone', $phone, PDO::PARAM_INT, 10);
$stmt->execute();

I keep getting this issue with PDO, where this error crops up in my tests.


<?php
require_once('simpletest/unit_tester.php');
require_once('simpletest/reporter.php');
require_once('../model.php');
class TestOfCallMapper extends UnitTestCase {
function testOfReturnsAll() {
}
function setUp() {
R::setup("mysql:host=localhost;dbname=poo", root, ');
$this->destroySchema();
$this->createSchema();
}
function tearDown() {
$this->destroySchema();
}
private function createSchema() {
R::exec(file_get_contents('../databa

I want to be able to get some output from mysql stored procedure within OUT params but for case when stored procedure also returns result set via select statement like one below.


DELIMITER $$
DROP PROCEDURE IF EXISTS `RD`.`sp`$$
CREATE DEFINER=`root`@`%` PROCEDURE `sp`(in b int, out a int)
BEGIN
select 664656 into a;
select 5;
END$$
DELIMITER ;

Runing in console below mentioned command one by one


call sp(5,@a)
select @a

we will get result
5 => 5
@a => 664656


However

Oh, the joys of a new server. The following code has always worked, and now I get some error 2014 related to unbuffered queries. Has anyone experienced this, and if so, how did you resolve it? Thanks

I'm sorry for asking this question. I've read alot just like it, but never found a solution that I successfully could implement. All the tips and tricks that I've found has been to no use for me.I have a large associative array with data that I want to insert into a mysql database using a stored procedure with PDO.$data_arr = {a lot of data with keys: Name, Nbr, Val} //This is really 41 columns$inputs = array('Name','Nbr','Val');$query = 'CALL add_edit_standard(:Name,:Nbr,:Val)';$stmt =
