When I run apache (via xampp) as a standalone server not as a service (on Windows Server 2008)
with the following connection code everything works fine (username and password removed )
$server = "WMS";
$link = odbc_connect($server,'','');
if (!$link) {
die('Something went horribly wrong while connecting to MSSQL');
}else {echo('');}
If however I change apache to run as a service in Windows the connection breaks and I get the following error message
Warning: odbc_connect() [function.odbc-connect]: SQL error: [Microsoft][ODBC Driver Manager]
Data source name not found and no default driver specified, SQL state IM002 in SQLConnect in
C:\xampp\htdocs\Dev\well.php on line 30
Something went wrong while connecting to MSSQL
Please read documentation: http://uk.php.net/manual/en/function.odbc-connect.php
$server = "WMS"; suggests that you have ODBC alias/data source configured with that name. Error message clearly says that data source with such name (WMS) is not found. On Windows 7/Vista/XP/Server you can configure them at "Start -> Administrative Tools -> Data Sources (ODBC)" -- path can be different on older OS. In any case -- look for "Microsoft ODBC Data Source Administrator".
Instead of using alias, I would recommend (the way I always connect) to use full DSN name, e.g.
// Microsoft SQL Server using the SQL Native Client 10.0 ODBC Driver - allows connection to SQL 7, 2000, 2005 and 2008
$link = odbc_connect("Driver={SQL Server Native Client 10.0};Server=$server;Database=$database;", $user, $password);
In this case everything is part of the script and no external dependencies.
BTW -- instead of using ODBC Functions, I would recommend using PDO & driver specially for MS SQL Server: PDO_SQLSRV -- http://uk.php.net/manual/en/ref.pdo-sqlsrv.php (or Microsoft SQL Server Driver for PHP if you prefer old procedural style -- http://uk.php.net/manual/en/book.sqlsrv.php )

I am trying to connect IBM-DB2 database using odbc_connect. Below is the sample script to test the connection for IBM-DB2 Database
$conn = odbc_connect("DRIVER={IBM DB2};SERVER=10.100.200.99;DATABASE=TESTDB;","john","doe");
if (!($conn)) {
echo "<p>Connection to DB via ODBC failed: ";
echo odbc_errormsg ($conn );
echo "</p>\n";
}
When executed in Windows it throws below exception
Warning: odbc_connect(): SQL error: [Microsoft][ODBC Driver Manager]
Data source name not found and no default driver specified, SQL state
IM002
When executed in Linux it throws below exception
Warning: odbc_connect(): SQL error: [unixODBC][IBM][CLI Driver]
SQL30081N A communication error has been detected. Communication
protocol being used: "TCP/IP". Communication API being used:
"SOCKETS". Location where the error was detected: "127.0.0.1"
How could I resolve above error and connect to IBM-DB2 database?
odbc_connect documentation
If you are using only a DSN in the connection string then the odbc.ini (or equivalent) needs to specify the other details (hostname/ip-address, port-number, database name) etc.
If you are not using a DSN in the connection string, then that connection-string must include the hostname/ip-address of the Db2-server, along with the port-number and database name and any other attributes you need.
Your symptom on Linux is most likely due to simple issues like incorrect or incomplete connection string or DSN definition, or Db2-instance not started, or Db2-instance not listening on specified port-number on specified IP-address.
PHP works fine with Db2 on Windows/Unix etc.
Consider using pdo_ibm or ibm_db2 extensions to PHP to have better integration between PHP and Db2 (although these are not related to your symptoms).
I am trying to connect to a SQL Server database from PHP but I'm having problems with the connection string. Here is a rundown of what I've tried and the effect it has had:
Running PHP 5.3.13, Apache 2.2.22, Windows 7, and SQL Server 2008 R2
I've installed SQL Server Native Client 11.0
I've dropped using MSSQL driver, using the SQLSRV driver instead.
Loaded these extensions in php.ini: extension=php_pdo_sqlsrv_53_ts.dll, extension=php_sqlsrv_53_ts.dll,
extension=php_pdo.dll.
phpinfo() shows these as active:
Registered PHP Streams php, file, glob, data, http, ftp, zip, compress.zlib, phar, sqlsrv
PDO drivers mysql, odbc, sqlite, sqlsrv
sqlsrv support enabled
Connection code is as follows:
$serverName = "[servername]";
$connectionInfo = array( "Database"=>"[databasename]");
$conn = sqlsrv_connect( $serverName, $connectionInfo);
if( $conn )
{
echo "Connection established.\n";
}
else
{
echo "Connection could not be established.\n";
die( print_r( sqlsrv_errors(), true));
}
The string is set up to use Windows authentication, which sqlsrv_errors() reports:
[message] => [Microsoft][SQL Server Native Client 11.0][SQL Server]Login failed for user '[networkname]\[machinename]'
I have also tried this using my network id/pwd, resulting in
[message] => [Microsoft][SQL Server Native Client 11.0][SQL Server]Login failed for user '[username]'
I do know that the database is up and functional, as I can connect and run queries without problem from the SQL Server client, and from sqlcmd. The SQL Client and the command line work when using my network/machine credentials. The command line client fails when I try with username/password. This would indicate that any PHP connection should use the Windows authentication to connect.
Someone in another thread suggested that changing permissions in a registry entry would work, but this did not help my issue. PHP 5.3 not recognizing Native Client to connect to MS SQL
I also had some success creating a system DSN. The connection test reports success:
Microsoft SQL Server Native Client Version 11.00.2100
Running connectivity tests...
Attempting connection
Connection established
Verifying option settings
INFO: A network alias was found for the DSN server. 'Protocol: DBMSSOCN; Address: [servername]' was used to establish the connection.
Disconnecting from server
TESTS COMPLETED SUCCESSFULLY!
I've searched extensively within stackoverflow.com, and the interwebs in general with no luck. Obviously the db connection is alive using other methods, but what is going wrong in my connection via PHP?
I got this solved by creating a new login using sql server authentication. I hope this helps somebody with similar issues.
SQLSRV uses the absence of a UID (uid==NULL || strlen(uid) ==0) to indicate that it should try set the "trusted connection" flag in the connection string, i.e. connect using the credentials implied by the execution context.
You can't pass a domain login and password (e.g. UID='MYDOMAIN\user') explicitly.
I had a weird compiler version issue with Microsoft's driver for PHP, and solved my connection problem with PHP's ODBC driver:
//$pdo = new PDO("sqlsrv:Server=$hostname;Database=$dbname;", $username, $password); // works with proper driver for PHP.
$pdo = new PDO("odbc:Driver={SQL Server};Server=$hostname;Database=$dbname;", $username, $password); // works with proper driver for ODBC and PHP ODBC.
I'm trying to connect using a string:
odbc:Driver={SQL Server Native Client 11.0};Server=(localdb)\v11.0;Database=test;uid=sa;password=123321;
Result: SQLSTATE[28000] SQLDriverConnect: 18456 [Microsoft][SQL Server Native Client 11.0][SQL Server]Login failed for user 'sa'.
When I try to connect using Windows ODBC Data Source Administrator the connection is successful.
What the problem might be in?
The network user 'sa' does not have permission to the Microsoft SQL Server.
The best way to provide network users access to Microsoft SQL Server is to create a Windows group (for example EGUSERS) and permit the Windows group Server Access at the Security Logins within Microsoft SQL Server.
Put all network users that need to have access to Microsoft SQL Server to the Windows group (EGUSERS).
Check if you have the right authentication mode set on the MSSQL Server:
https://msdn.microsoft.com/en-us/library/ms188670.aspx
Also you have two ways to connect to MSSQL through PHP/PDO by using the PHP_PDO_ODBC extension which uses the ODBC driver given in the connectionstring or use PHP_PDO_SQLSRV_xx_TS or PHP_PDO_SQLSRV_xx_NTS extension which you can find here (only for 32bit PHP!) https://www.microsoft.com/en-us/download/details.aspx?id=20098 or use the unofficial 64bit here http://robsphp.blogspot.nl/2012/06/unofficial-microsoft-sql-server-driver.html
connection string when using PHP_PDO_SQLSRV_xx_(N)TS extension:
$hostname='127.0.0.1';
$dbname='test';
$username='user';
$password='pw';
$dbDB = new PDO("sqlsrv:Server=$hostname;Database=$dbname", $username, $password);
connection string when using PHP_PDO_ODBC extension:
//use any of these or check exact MSSQL ODBC drivername in "ODBC Data Source Administrator"
$mssqldriver = '{SQL Server}';
$mssqldriver = '{SQL Server Native Client 11.0}';
$mssqldriver = '{ODBC Driver 11 for SQL Server}';
$hostname='127.0.0.1';
$dbname='test';
$username='user';
$password='pw';
$dbDB = new PDO("odbc:Driver=$mssqldriver;Server=$hostname;Database=$dbname", $username, $password);
When testing a simple query which returned 66 records using PHP_PDO_ODBC extension took ~500ms (for all three MSSQL ODBC drivers) but when using the 64bit(!) PHP_PDO_SQLSRV_TS it took ~5000ms. 10 times slower! Have not yet tried 32bit or the NTS variant.
My dev PC is Windows 7 SP1 using WAMPx64 PHP 5.5.12 and I used PHP_PDO_SQLSRV_55_TS
I cannot connect to a SQL server database from my Mac. Here's my PHP code:
$db = &ADONewConnection('odbc_mssql');
$db->debug = true;
$myDSN="DRIVER={SQL Server Native Client 10.0};SERVER=XXX.XXX.XXX.XX;PORT=1433;UID=XXXX;PWD=XXXXX;DATABASE=XXXXX;";
$db->Connect($myDSN);
I've tried a whole bunch of different drivers (FreeTDS, SQL SERVER, SQL Server Native Client etc.) but I keep getting this error:
SQL error: [unixODBC][Driver Manager]Data source name not found, and no default driver specified, SQL state IM002
FYI, I've installed php5-mssql, freetds and unixODBC.
Thanks in advance for your help.
The error is trying to tell you that you do not have a "DRIVER={SQL Server Native Client 10.0};" on your machine.
This comes as no surprise since the SQL Server Native Client is only available on Windows.
What you need is a third party ODBC driver (or the like) such as the OpenLink Single-tier ODBC Driver for SQL Server
We are using MSSQL server 2008 on Win server 2008 R2 and have installed Apache (2.2.19) and PHP (5.2.17) separately. We have installd the MSSQL module for PHP and usingthe following connection string:
$myc = mssql_connect(Server, SiteDatabaseUsername, SiteDatabasePassword) or die('Can\'t connect to mssql Database Server: '.mssql_get_last_message($myc));
$db = mssql_select_db(SiteDatabaseName, $myc) or die('Can\'t find database: '.mssql_get_last_message($myc));
But it gives us this error:
Warning: mssql_connect() [function.mssql-connect]: Unable to connect to server: localhost\MSSQLSERVER in D:\Apache2.2\htdocs\adminarea\_core.php on line 89
Can't connect to mssql Database Server:
We have used the IP:PORT, localhost\MSSQLSERVER and COMPUTERNAME\MSSQLSERVER but don't seem to be getting anywhere, can anyone help please?
A few things come to mind:
1) Make sure you have the sqlsrv driver package from MS, and make sure you're loading it properly in php.ini (use phpinfo() to verify).
2) If this was a vanilla installation of SQL Server, its likely that only windows authentication is turned on. Open the SQL Enterprise Manager and make sure you have SQL Server Authentication enabled on your database.
3) Make sure that you have enabled network access to SQL Server. I'm not immediately certain whether the new MS drivers use named pipes to communicate with the server, or if they expect that the server will be accessed via the network.
These are the issues I routinely encounter when getting PHP speaking to a new MSSQL server.
