Code I'm using to test connection:
$serverName = 'host\sqlexpress';
$database = 'dbname';
// Get UID and PWD from application-specific files.
$uid = 'username';
$pwd = 'password';
try {
$conn = new PDO( "sqlsrv:server=$serverName;Database = $database", $uid, $pwd);
$conn->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION );
}
catch( PDOException $e ) {
die( "Error connecting to SQL Server" );
}
echo "Connected to SQL Server\n";
$query = 'select * from tablename';
$stmt = $conn->query( $query );
while ( $row = $stmt->fetch( PDO::FETCH_ASSOC ) ){
print_r( $row );
}
// Free statement and connection resources.
$stmt = null;
$conn = null;
?>
The error I'm getting when running this file is just, "Error connecting to SQL Server"
Any clue why this may not be working? Any way I can get a more detailed error report?

Hi I had a question about connecting php to sql server I install odbc driver and confige php.ini file. But when execute I get error.
I change the computer but still get same error.
<?php
$serverName = "YASSERAHMMED\YASOFT";
$connectionInfo = array( "Database"=>"ELECTERC_DB", "UID"=>"sa", "PWD"=>"google");
$con = sqlsrv_connect( $serverName, $connectionInfo );
if( $con === false ) {
//echo sqlsrv_errors();
die( print_r( sqlsrv_errors(), true));
}
$sql = "SELECT * FROM ACCOUNT_CUSTMERS";
$stmt = sqlsrv_query( $con, $sql );
if( $stmt === false) {
die( print_r( sqlsrv_errors(), true) );
}
while( $row = sqlsrv_fetch_array( $stmt, SQLSRV_FETCH_ASSOC) ) {
echo $row['date'].", ".$row['id']."<br />";
}
sqlsrv_free_stmt( $stmt);
?>
the result is :
error 5701 and 5703
I finally use PDO string connection to resolve the problem..
thanks every one...
$serverName = "YASSERAHMMED\YASOFT";
try
{
$conn = new PDO( "sqlsrv:server=$serverName ; Database=ELECTERC_DB", "", "");
$conn->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION );
if($conn){
// echo'ggggg';
} else{
echo'undone';
}
}
catch(Exception $e)
{
die( print_r( $e->getMessage() ) );
}
I have a local MS SQL Database, and a web PHP application on IIS on my server.
On IIS I have successfully connected PHP and my MS SQL database (added connection strings and i see my tables)
But, when I use any SQL select in the PHP web application, it does not work. No data is displayed, or any erros, for example :
/* Connect to a MySQL database using driver invocation */
$dsn = 'mysql:dbname=dbname;host=localhost';
$user = 'dbuser';
$password = 'dbpass';
try {
$dbh = new PDO($dsn, $user, $password);
} catch (PDOException $e) {
echo 'Connection failed: ' . $e->getMessage();
}
$results = mysql_query("SELECT id FROM users");
while($row = mysql_fetch_array($results)) {
$name = $row['id']
?>
<tr>
<td><?php echo '$name'?></td>
</tr>
<?php
}
?>
</tbody>
</table>
follow like this for pdo connection
$sql = $dbh->prepare("SELECT id FROM users");
$sql->execute();
while($result = $sql->fetch(PDO::FETCH_ASSOC)){
?>
<tr>
<td><?php echo $result['name'];?></td>
</tr>
<?php } ?>
Please follow that code:
$host = '127.0.0.1';
$db = 'test';
$user = 'root';
$pass = '';
$charset = 'utf8';
$dsn = "mysql:host=$host;dbname=$db;charset=$charset";
$opt =
[
PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION,
PDO::ATTR_DEFAULT_FETCH_MODE => PDO::FETCH_ASSOC,
PDO::ATTR_EMULATE_PREPARES => false,
];
$pdo = new PDO($dsn, $user, $pass, $opt);
$stmt = $pdo->query('SELECT name FROM users');
while ($row = $stmt->fetch())
{
echo $row['name'] . "\n";
}
MS SQL (or SqlSrv) and MySql are not working on the sames drivers. You have to know which one you are using and the find PHP functions ables to deal with it.
Note: PHP Extension for using driver must be installed on your server and activated on php.ini file
For MySql do not use mysql_xxx() deprecated functions, prefer mysqli_xxx() to them.
You can find here docs and samples code for both mysql & mssql php functions :
MySql :
http://php.net/mysqli_connect
php.net/mysqli_fetch_array
SqlSrv :
http://php.net/sqlsrv_connect
php.net/sqlsrv_fetch_array
So what is your database engine ?
Hope that'll helps you, cheers
Mixing the apis would not work - use only PDO methods like this perhaps
/* Connect to a MySQL database using driver invocation */
try {
/* mysql server */
/* $dsn = 'mysql:dbname=dbname;host=localhost'; */
/* MS SQL Server */
$dsn = 'sqlsrv:Database=dbname;Server=localhost';
$user = 'dbuser';
$password = 'dbpass';
$dbh = new PDO($dsn, $user, $password);
$sql='select * from users';
$results=$dbh->query( $sql );
if( $results ){
while( $rs=$results->fetch( PDO::FETCH_OBJ ) ){
echo "<tr><td>{$rs->name}</td></tr>";
}
}
} catch (PDOException $e) {
echo 'Connection failed: ' . $e->getMessage();
}
Now working great also with select, with this code :
<?php
$serverName = "AC-CLOUD"; //serverName\instanceName
$connectionInfo = array( "Database"=>"Data", "UID"=>"sa", "PWD"=>"Masterkey2010");
$conn = sqlsrv_connect( $serverName, $connectionInfo);
if( $conn ) {
echo "Connection established.<br />";
}else{
echo "Connection could not be established.<br />";
die( print_r( sqlsrv_errors(), true));
}
$sql = "SELECT Code, Name FROM StoreCards";
$stmt = sqlsrv_query( $conn, $sql );
if( $stmt === false) {
die( print_r( sqlsrv_errors(), true) );
}
while( $row = sqlsrv_fetch_array( $stmt, SQLSRV_FETCH_ASSOC) ) {
echo $row['Code'].", ".$row['Name']."<br />";
}
sqlsrv_free_stmt( $stmt);
?>
How now i set this two values into table? this is last point. thank you for your patience and time.
I could not insert values in table (MSSQL) by using pdo php. I got message that connection is established but query does not work. I have never used MSSQL server I am not sure is this query good.
$database = "db";
$server = "xxx\SQLEXPRESS";
$conn = array( "Database"=>"db", "UID"=>"user", "PWD"=>"xxx" , "CharacterSet" => "UTF-8");
if( $conn ) {
echo "connection established";
}else{
echo "Connection could not be established.";
die( print_r( sqlsrv_errors(), true));
}
// insert values into table,
// variables are defined above didnt write them here
$query = $conn->prepare("INSERT INTO dbo.FKNarudzbaKupacaStavke(IdFirma, VrstaDokumenta, BrojDokumenta, BrojDokumentaKroz,
DatumDokumenta, IdKupac, VrstaCijene, NacinPlacanja, DatumZadnjeAkcije, Status, StatusArhive, StatusIzmjene,
StatusStampe, VrstaFakture) VALUES(:IdFirma, :VrstaDokumenta, :BrojDokumenta, :BrojDokumentaKroz, :DatumDokumenta, :IdKupac, :VrstaCijene, :NacinPlacanja,
:DatumZadnjeAkcije, :Status, :StatusArhive, :StatusIzmjene, :StatusStampe, :VrstaFakture)");
$query->bindParam(':IdFirma',$IdFirma);
$query->bindParam(':VrstaDokumenta',$VrstaDokumenta);
$query->bindParam(':BrojDokumenta',$BrojDokumenta);
$query->bindParam(':BrojDokumentaKroz',$BrojDokumentaKroz);
$query->bindParam(':DatumDokumenta',$DatumDokumenta);
$query->bindParam(':IdKupac',$IdKupac);
$query->bindParam(':VrstaCijene',$VrstaCijene);
$query->bindParam(':NacinPlacanja',$NacinPlacanja);
$query->bindParam(':DatumZadnjeAkcije',$DatumZadnjeAkcije);
$query->bindParam(':Status',$Status);
$query->bindParam(':StatusArhive',$StatusArhive);
$query->bindParam(':StatusIzmjene',$StatusIzmjene);
$query->bindParam(':StatusStampe',$StatusStampe);
$query->bindParam(':VrstaFakture',$VrstaFakture);
$query->execute();
I got this error :
Fatal error: Call to a member function prepare() on a non-object..
Any help or advice is appreciated!
The way you've written it, $conn isn't a connection, it's just an array.
Try this to connect to the database:
$hostname = 'xxx\SQLEXPRESS';
$username = 'user';
$password = 'xxx';
$dbname = 'db';
$conntype = 'mysql'; //or dblib or mssql
try {
$conn = new PDO("$conntype:host=$hostname;dbname=$dbname", $username, $password);
}
catch( PDOException $e ) {
echo( $e->getMessage() );
}
You are actually not establishing the connection there, please change your $conn variable as show below
$conn = new PDO("mssql:host=".$server.";dbname=db", "user", "xxx");
I am trying to select rows from my database table, and I am getting an error stating that
Fatal error: Call to a member function query() on null in..
Our connection to the database shows successful. Below is my php code:
<?php
require_once("dbconn.php");
$db = getConnection();
$input_pid = "870104-07-5448";
$sql = "SELECT * FROM Pat WHERE PID ='$input_pid'";
$stmt = $db->query($sql);
$row = $stmt->fetchObject();
echo $row->PID;
echo $row->Name;
?>
This is the dbconn.php code:
function getConnection(){
try {
$hostname = "busctrlctr-pc";
$dbname = "DispenserSystem";
$username = "sa";
$password = "123456";
$db = new PDO ("sqlsrv:Server=$hostname;Database=$dbname", $username, $password);
echo 'We are succesful to connect the database !!'.'<br>'; // successful word
} catch (PDOException $e){
echo "connection failed problem is >> ". $e -> getMessage()."\n";
exit;
}
}
Can i know why I am getting this error. Thank you.
You never return $db in your funtion getConnection();
change the funtion to:
function getConnection(){
try {
$hostname = "busctrlctr-pc";
$dbname = "DispenserSystem";
$username = "sa";
$password = "123456";
$db = new PDO ("sqlsrv:Server=$hostname;Database=$dbname", $username, $password);
echo 'We are succesful to connect the database !!'.'<br>'; // successful word
return $db;
} catch (PDOException $e){
echo "connection failed problem is >> ". $e -> getMessage()."\n";
exit;
}
}
I want to connect to a sql Server.. Only it won't work.
I granted a user and role enough permissions. But what am I doing
<?php
$serverName = "LERAARSKAMER01\SQLEXPRESS";
$database = "sqlservertest";
// Get UID and PWD from application-specific files.
$uid = "sqlAdmin";
$pwd = "tester";
try {
$conn = new PDO( "sqlsrv:server=$serverName;Database = $database", $uid, $pwd);
$conn->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION );
}
catch( PDOException $e ) {
die( "Error connecting to SQL Server" );
}
echo "Connected to SQL Server\n";
$query = 'select * from dbo.users';
$stmt = $conn->query( $query );
while ( $row = $stmt->fetch( PDO::FETCH_ASSOC ) ){
print_r( $row );
}
// Free statement and connection resources.
$stmt = null;
$conn = null;
?>
This is a screenshot of the server...
What is wrong?
After searching for a while I found I have to set sql Authentication on.
Microsoft SQL Managment Studio --> Database (right click-> properties->security)
Then I enabled sa, changed the password and settings with this (password policy,...).
It works also with sqlAdmin (the other user). Just with the same code..
USE Master
GO
ALTER LOGIN test_must_change WITH PASSWORD = ‘samepassword’
GO
ALTER LOGIN test_must_change WITH
CHECK_POLICY = OFF,
CHECK_EXPIRATION = OFF;
