SQL Takes too much - php

Question

For some reason my script takes too much time, that is why i had to add the ini_set('max_execution_time', 300); since 30 seconds being the default got me a fatal error.
I can't understand why this is happening, if i go directly into SSMS i get that query in 0 secs. what can be happening? i am running wamp with php 5.4.16 and the extension php_sqlsrv_54_ts
<?php
error_reporting(E_ALL ^ E_DEPRECATED);
ini_set('max_execution_time', 300);
include "ChromePhp.php";
$sort = isset($_POST['sort']) ? strval($_POST['sort']) : 'Cliente';
$order = isset($_POST['order']) ? strval($_POST['order']) : 'DESC';
include "includes/db_config.php";
$conn = sqlsrv_connect(SV_NAME, $connectionInfo) OR die("Unable to connect to the database");
$sql =
"SELECT * FROM
(Select
Id
,Cliente
,Contrato
,Anexo
,SO
,NombreFlota
,(SELECT count(*) FROM LiveTest LEFT JOIN Producto ON Producto.Id=LiveTest.Producto_Id WHERE Producto.Order_Id=Orders.Id) as Hechas
,((SELECT count(*) FROM Producto WHERE Order_Id=Orders.Id) - (SELECT count(*) FROM LiveTest LEFT JOIN Producto ON Producto.Id=LiveTest.Producto_Id WHERE Producto.Order_Id=Orders.Id and RMA is null )) as Pendientes
,(SELECT count(*) FROM Producto WHERE Order_Id=Orders.Id ) as Total
FROM
Orders
WHERE
Orders.FechaPick is not null) as A
WHERE Total - Pendientes >0
ORDER BY $sort $order";
ChromePHP::log($sql);
$params = array();
$options = array( "Scrollable" => SQLSRV_CURSOR_KEYSET );
$result = array();
$res = sqlsrv_query($conn, $sql, $params, $options);
while($row = sqlsrv_fetch_object($res))
{
array_push($result, $row);
}
ChromePHP::log($result);
echo json_encode($result);
?>

Answer 1

try to modify your query like this:
Note : you do 'where f0b.Order_Id=f1.Id' then your left ouer join is cancelled because you test a value (that's why i have replaced by inner join), if you want null value too, you must do it : 'where f0b.Order_Id=f1.Id or f0b.Order_Id is null'
Select
Id
,Cliente
,Contrato
,Anexo
,SO
,NombreFlota
,isnull(f3.NbProdLive, 0) as Hechas
,isnull(f2.NbProd, 0) - isnull(f3.NbProdLiveRMANull, 0) as Pendientes
,isnull(f2.NbProd, 0) as Total
FROM
Orders f1
outer apply
(
select count(*) NbProd from Producto f0
where f0.Order_Id=f1.Id
) f2
outer apply
(
select count(*) NbProdLive, sum(case when RMA is null then 1 else 0 end) NbProdLiveRMANull
from LiveTest f0 INNER JOIN Producto f0b ON f0b.Id=f0.Producto_Id
where f0b.Order_Id=f1.Id
) f3
WHERE f1.FechaPick is not null and (isnull(f2.NbProd, 0) - (isnull(f2.NbProd, 0) - isnull(f3.NbProdLiveRMANull, 0))) >0
ORDER BY $sort $order
