SELECT * FROM dbo.Warehouse returns result, but when I change to SELECT * FROM dbo.Accessories, it neither shows any result nor echo 'Rows not found'. Both Warehouse and Accessories tables have rows. Here is my script.
<?php
require('db_connect.php');
$query = 'SELECT * FROM dbo.Warehouse';
$params = array();
$options = array( "Scrollable" => SQLSRV_CURSOR_KEYSET );
$stmt = sqlsrv_query($conn, $query, $params, $options);
if(!$stmt){
die(print_r(sqlsrv_errors(),true));
}
$c = 0;
$result[] = array();
if(sqlsrv_num_rows($stmt) != 0){
while($row = sqlsrv_fetch_array($stmt, SQLSRV_FETCH_ASSOC)){
$row = array($c => $row);
$result[$c] = $row;
$c++;
}
} else {
echo("Rows not found");
}
echo json_encode($result);
?>
Please help me, thanks in advance. :(

I'm using the sqlsrv extension for php and have a problem with fetching the rows from a simple query.
My query is a select which should return 133228 rows but when trying to display the rows I get only 15.
I've searched for an answer but couldn't find a solution and this is my first time using this extension. I've found an answer to a previous question about the same problem but in that case the problem was double calling of sqlsrv_fetch_array, which I don't have for sure.
Here is my query:
$sql = 'select * from ViewProduct';
$params = array();
$options = array('Scrollable' => SQLSRV_CURSOR_KEYSET);
$stmt = sqlsrv_query($dbRemote, $sql, $params, $options);
$count = sqlsrv_num_rows($stmt);
if ($count === false)
echo "Error in retrieveing row count.";
else
echo $count;
//$rows = array();
while ($row = sqlsrv_fetch_array($stmt, SQLSRV_FETCH_ASSOC)) {
print_r($row);
echo "<br>";
//$rows[] = $row;
}
As I said the above query returns 15 when should be 133228 rows.
What am I missing?
Thank you in advance.
i have same problem,
this is my solution for this
$data = [];
$result_num = false;
// get rows num if have any
$result_count_res = sqlsrv_query(
$conn,
$query,
[],
[ "Scrollable" => SQLSRV_CURSOR_KEYSET ]
);
if( $result_count_res === false) {
echo "Row count false";
}else{
// set row num
$result_num = sqlsrv_num_rows( $result_count_res );
}
if($result_num){
// run another query to retrive results
$result_res = sqlsrv_query(
$conn,
$query,
[],
[ "Scrollable" => SQLSRV_CURSOR_FORWARD ]
);
if( $result_res === false) {
// get errors from query
die( print_r( sqlsrv_errors(), true) );
}else{
// run through "for" loop to retrive all results
for($i = 0; $i < $result_num; $i++){
$data[] = sqlsrv_fetch_array( $result_res, SQLSRV_FETCH_ASSOC);
}
}
sqlsrv_free_stmt( $result_res );
}else{
echo "Row count false";
}
echo '<pre>';
var_dump($data);
echo '</pre>';
I am Using Following code php array to encode Json
$query = "SELECT * FROM register WHERE email='$email'AND password='$password'AND status!='0'";
$result = mysql_query($query) or die('Errant query: ' . $query);
$numResults = mysql_num_rows($result);
if ($numResults > 0)
{
$data = array();
while ($row = mysql_fetch_assoc($result))
{
$data = $row;
}
echo json_encode($data);
}
IT gives Me result like
{"id":"26","fname":"Shankar","lname":"Salunkhe","category_name":"2"}
But I wanted To result like
{"SignIn":[{"id":"26","fname":"Shankar","lname":"Salunkhe","category_name":"2"}],"errors":[],"totalNumberOfRecords":1,"responseCode":"00000"}
How Can I do That
Or Suggest Me any other Method to do that
You need to do something like below to get the desired output.
$query = "SELECT * FROM register WHERE email='$email'AND password='$password'AND status!='0'";
$result = mysql_query($query) or die('Errant query: ' . $query);
$numResults = mysql_num_rows($result);
if ($numResults > 0)
{
$data = array();
while ($row = mysql_fetch_assoc($result))
{
$data[] = $row;
}
$result = ['SignIn' => $data, 'totalNumberOfRecords' => $numResults, 'errors' => [], 'responseCode' => 0000];
echo json_encode($result);
exit;
}
You have to store all information in a array to get what you want.
For example,
$data = array("id" =>"26","fname"=>"Shankar","lname"=>"Salunkhe","category_name"=>"2");
$array = array("SignIn" => $data, "errors" => [], "totalNumberOfRecords" => 1,"responseCode" => "00000");
$result = json_encode($array);
Hi I'm new in PHP and trying to get the below response using php sql but i'm not be able to find the such desire output
[{"Id":1, "name": "India", "Cities":[{"Id":1, "Name":"Mumbai", "country_id":1}, {"Id":2,"Name":"Delhi","country_id":1},
"id":3,"Name":Banglore","country_id":1}, {"Id":2, "Name":"USA", "Cities":[{"Id":6, "Name":"New York", "country_id":2},.....
I have two tables one is country based and other is city based.
I tried
<?php
include_once("config.inc.php");
$sql = "SELECT * FROM country";
$sqlCity = "SELECT * FROM city";
$cityQuery = mysqli_query($conn, $sqlCity);
$sqlQuery = mysqli_query($conn, $sql);
$mainArray = array();
if(mysqli_num_rows($cityQuery) > 0 ){
$cityResponse = array();
while($resCity = mysqli_fetch_assoc($cityQuery)){
$cityResponse[] = $resCity;
}
if(mysqli_num_rows($sqlQuery) > 0 ){
$response = array();
while($res = mysqli_fetch_assoc($sqlQuery)){
$response[] = $res;
}
foreach($cityResponse as $city){
foreach($response as $country){
if($city['country_id'] == $country['id']){
$mainArray = array("Cities" => $city);
}
}
}
echo '{"response": '.json_encode($response).', '.json_encode($mainArray).' "success": true}';
}
}else{
echo '{"response": '.json_encode($response).' "success": false}';
}
?>
currently my response showing
{"response": [{"id":"1","name":"India"},{"id":"2","name":"USA"},{"id":"3","name":"UK"}], {"Cities":{"id":"15","name":"Manchester","country_id":"3"}} "success": true}

Modify the SQL query with related column names
The memory you have to take care. By default memory limit in php is 128MB in 5.3
Check the code and let me know the result
<?php
$data = array();
//include your database configuration files
include_once("config.inc.php");
//execute the join query to fetch the result
$sql = "SELECT country.country_id, country.name AS country_name,".
" city.city_id, city.name AS city_name FROM country ".
" JOIN city ON city.country_id=country.country_id ".
" ORDER BY country.country_id ";
//execute query
$sqlQuery = mysqli_query($conn, $sql) or die('error exists on select query');
//check the number of rows count
if(mysqli_num_rows($sqlQuery) > 0 ){
//country id temprory array
$country_id = array();
//loop each result
while($result = mysqli_fetch_assoc($sqlQuery)){
//check the country id is already exist the only push the city entries
if(!in_array($result['country_id'],$country_id)) {
//if the city is for new country then add it to the main container
if(isset($entry) && !empty($entry)) {
array_push($data, $entry);
}
//create entry array
$entry = array();
$entry['Id'] = $result['country_id'];
$entry['name'] = $result['country_name'];
$entry['Cities'] = array();
//create cities array
$city = array();
$city['Id'] = $result['city_id'];
$city['name'] = $result['city_name'];
$city['country_id'] = $result['country_id'];
//append city entry
array_push($entry['Cities'], $city);
$country_id[] = $result['country_id'];
}
else {
//create and append city entry only
$city = array();
$city['Id'] = $result['city_id'];
$city['name'] = $result['city_name'];
$city['country_id'] = $result['country_id'];
array_push($entry['Cities'], $city);
}
}
}
//display and check the expected results
echo json_encode($data);
use like this
<?php
include_once("config.inc.php");
$sql = "SELECT * FROM country";
$sqlCity = "SELECT * FROM city";
$cityQuery = mysqli_query($conn, $sqlCity);
$sqlQuery = mysqli_query($conn, $sql);
$mainArray = array();
if(mysqli_num_rows($cityQuery) > 0 ){
$cityResponse = array();
while($resCity = mysqli_fetch_assoc($cityQuery)){
$cityResponse[] = $resCity;
}
if(mysqli_num_rows($sqlQuery) > 0 ){
$response = array();
while($res = mysqli_fetch_assoc($sqlQuery)){
$response[] = $res;
}
foreach($cityResponse as $city){
foreach($response as $country){
if($city['country_id'] == $country['id']){
$mainArray = array("Cities" => $city);
}
}
}
echo json_encode(array('result'=>'true','Cities'=>$mainArray));
}
}else{
echo json_encode(array('result'=>'false','Cities'=>$response));
}
?>
You can use try this. It actually works for me and it's cool. You can extend to 3 or more tables by editing the code.
try {
$results = array();
$query = "SELECT * FROM country";
$values = array();
$stmt = $datab->prepare($query);
$stmt->execute($values);
while($country = $stmt->fetch(PDO::FETCH_ASSOC)){
$cities = null;
$query2 = "SELECT * FROM city WHERE country_id = ?" ;
$values2 = array($country['id']);
$stmt2 = $datab->prepare($query2);
$stmt2->execute($values2);
$cities = $stmt2->fetchAll();
if($cities){
$country['cities'] = $cities;
} else {
$country['cities'] = '';
}
array_push($results, $country);
}
echo json_encode(array("Countries" => $results));
} catch (PDOException $e) {
throw new Exception($e->getMessage());
}
Given the following code:
function fetchData($mysqli){
$sql = "select * from `test`";
$result = mysqli_query($mysqli,$sql);
return $result;
}
$result = fetchData($mysqli);
while($row = mysqli_fetch_array($result)){
echo $row['id'];
}
My code is obviously more complicated than this. It loops itself until it yields some results changing some variables at each iteration.
$result is empty. What am I doing wrong? Thank you!
FULL CODE:
function fetchItem($itemID, $period, $mysqli){
$periodArray = array('7', '30', '60', '90', '180');
while (current($periodArray) !== $period) next($periodArray);
$currentPeriod = current($periodArray);
$sql = "SELECT * from `test` where `period` = '$period'";
$result = mysqli_query($mysqli,$sql);
$row_count = $result->num_rows;
if($row_count < 5){
$currentPeriod = next($periodArray);
fetchItem($itemID, $currentPeriod, $mysqli);
} else if($row_count >= 5){
$currentPeriod = current($periodArray);
$rows = array();
while ($row = $result->fetch_assoc()) {
$rows[] = $row;
}
// var_dump($rows); <-- returns all results
return $rows;
}
}
$output = fetchItem($itemID, $period, $mysqli);
echo '<pre>';
print_r($output); <-- NULL
echo '</pre>';
As you can see if I don't get results for a given period it moves onto the next one.
Your code should be:
function fetchData($mysqli){
$sql = "select * from `test`";
$init = mysqli_query($mysqli, $sql);
$result = $init->fetch_array(MYSQLI_ASSOC);
return $result;
}
$result = fetchData($mysqli);
foreach($result as $row){
echo $row['id'];
}
well... why doesn't work this sql statement?
public function searchProfile() {
$termino = $this->term;
$termino = "%".$termino."%";
$sql = "SELECT * FROM cat_perfiles WHERE UPPER(Nombre) LIKE UPPER(:term)";
$result = $this->dbConnect->prepare($sql) or die ($sql);
$result->bindParam(':term',$termino,PDO::PARAM_STR);
$numrows = $result->rowCount();
$jsonSearchProfile = array();
if ($numrows > 0) {
while($row = $result->fetch(PDO::FETCH_ASSOC)) {
$jsonSearchProfile[] = array(
'IdPerfil' => $row['Id'],
'NomPerfil' => $row['Nombre'],
'DesPerfil' => $row['Descripcion'],
'EdoPerfil' => $row['Activo']
);
}
$jsonSearchProfile['success'] = 'success';
return $jsonSearchProfile;
} else {
return false;
}
}
I check data from $this->term and is correct! But when compare with LIKE doesn't work.
I hope can help me!
You forgot to execute the query
$result->execute();
