I'm failing to connect to a SQL server SQLExpress. The connection worked fine a few days ago.
This is how I tried to connect (I'm using Microsoft SQL server management studio):
connection = pyodbc.connect("DSN=sqlServer; UID=myuser;PWD=mypassword")
cursor = connection.cursor()
The error I get:
('HYT00', '[HYT00] [Microsoft][ODBC SQL Server Driver]Login timeout expired (0) (SQLDriverConnect)')
In the ODBC Data Source Administrator, when I test the data source I get:
I got the similar issue.
The problem was actually I was using "SQL Server" as the driver in my ODBC settings in my DSN.
The driver should be "SQL Server Native Client 11.0".
It fixed the issue for me.
Because you are having the same issue in the ODBC Data Source Administrator I would try to focus on that first not on your code.
Here you can find a list with possible problems
Maybe this can help you find out what the problem is.
I also would try to connect with the SQL Server Management Studio.
Maybe it is possible to connect with a different user or via Windows login.
That would mean that your user might not exist anymore (maybe because you renewed tha database or something).
Also I sometimes have the problem that the SQL Server is not started either locally or on the server.
Maybe you could check if the service is started and the database is running.

I searched through all threads on the web available, but none could help me.
I am trying to connect to SQL Server engine from SQL Developer. In order to do that I enabled Named Pipes and TCP/IP from SQL Configuration Manager.
Then I tried different drivers:
I tried Microsoft JDBC driver for SQL Server - I cannot choose in connection manager SQL Server database type, so it does not work..
I tried jTDS driver instead, and it worked - I can choose SQL Server database type, but then all I get is an error informing that it cannot connect to Microsoft SQL Server on localhost (I tried localhost, name of my computer, none of which worked).
Is there anything more I can do?
EDIT
This is what I have so far:
SECOND EDIT
I had more problems:
With error saying
Status: Failur-I/O Error: SSO Failed: Native SSPI library not loaded. Check the java.library.path system property
Using windows authentication, I still got asked for username and password.
(All details and solutions in my answer below)
We only support the jTDS driver for SQL Server and Sybase ASE connections, so that's the way to go.
After that, it's up to you to get a correct connection string to your SQL Server system.
Make sure you have the right port in addition to your 'localhost' network location for your SQL Server instance.
This is using version 19.1 of SQL Developer to connect to a SQL2012 instance overseas..
Actually there were more problems, which I'll post here along with solutions:
In order to ba able to connect SQL Server database type from SQL developer it is needed to install jTDS driver, as already mentioned. Other types are not supported by SQL Developer.
Next thing was to configure with SQL Configuration Manager (the easiest way IMO) SQL Server to listen on IP port 1433, not dynamic, as was previously set. In order to do that in configuration manager I had to go to SQL Server Network Configuration and make appropriate changes. More here.
Next I had problem:
Status: Failur-I/O Error: SSO Failed: Native SSPI library not loaded. Check the java.library.path system property
Which was the fault of missing file, solution was placing file ntlmauth.dll to the /jdk/bin in SQL Developer directory.
I chose Windows authentication, which apparently is not supported by jTDS, so I needed to create user in SQL Server, which I use to connect SQL Server from SQL Developer.
After all that, I had it working.
I've tried to connect an SQL database from a server with Microstrategy located in another server through an ODBC connector for SQL.
First I've checked that there is a connection between the two servers executing a ping sentence with the IP Address the other server and it went through.
After making sure the connection is stablished without issues, I've tried to connect through Microstrategy without success. The error I get is the following message:
"Connection test error: Connect failed. Error type Odbc error. Odbc operation attempted: SQLDriverConnect (08001:0: on SQLHANDLE)"
Using SQL Server 2017 for the databases and Microstrategy 10.4.
Please, anybody has any clue about what might be happening?
Thanks,
look at the type of connector to the db you have. It gave me the same error until I used: "with Native Client Driver".
Could you please share the complete error message, SQL Handle error are associated with multiple error scenarios like invalid username * password, connecting 64 bit server with 32 bit ODBC driver etc. Complete error message would help me to debug it.
In general follow the steps to debug the error, (any order)
Check the version of ODBC Connection (64bit / 32 bit), it should be the same as server version.
Try testing the ODBC connection that you have created using ODBC Administrator tools to see whether there is an problem with username & password/server name or database connection issue.
Check the Database Instance/Database Connection/User Login created under the Administration option to ensure everything is working and give the correct value.
if nothing works try using the native driver given by MicroStrategy, you can access this using Connectivity Wizard.
Hope it helps..
I am trying to connect to one of my MS SQL Server databases with the Filemaker Pro ODBC driver. I am using the database service. However, whenever I try to connect to my database it sends either an error that it can't connect to the datasource or an error that the username or password is incorrect. I know the credentials I am using are correct because I can connect to my Jetbrains IDE and to the mssql library in node.js with the same credentials. Does anyone know what the problem could be? My database is running on Azure. Do any setting need to be changed in the driver based on using Azure that could cause the problem?
I am trying to connect local instance in my SSMS 2005. it is showing me this error.. while i can connect the my system instance remotely or using Code. Last time it was working 2 days ago. now how suddenly this can happen.
In the Sql Server Configuration Manager->SQL Server Network Configuration->Protocols for MSSQLSERVER (or the name of your instance) check if TCP/IP Protocol is Enabled. If not, set to...
SQL Server Configuration Manager
If the solution above isn´t work. I suggest you uninstall and reinstall SQL Server native client on the local computer
I'm trying to use PHP to connect to an ODBC data source using Windows authentication. I can connect just fine to the server in SQL Server so I know it's running. When I try to run the command
$link = odbc_connect("my_odbc","","");
I get the error:
"Warning: odbc_connect(): SQL error: [Microsoft][ODBC Driver 11 for SQL Server][SQL Server]Login failed for user ''., SQL state 28000 in SQLConnect in C:\Users..."
I tried:
$link = odbc_connect("Driver={ODBC Driver 11 for SQL Server};
Server='my_odbc';Integrated Security=SSPI","","");
Which returned the message:
Warning: odbc_connect(): SQL error: [Microsoft][ODBC Driver 11 for SQL Server]Named Pipes Provider: Could not open a connection to SQL Server [53]. , SQL state 08001 in SQLConnect in C:\Users..."
Not sure what I'm doing wrong.
my_odbc is a SQL Server (2008) on a different machine. I don't have admin privileges on that database so I can't change anything on that end (such as enabling SQL Server authentication).
I am running Windows 7 and using PHP Version 5.6.12
phpinfo() indicates that ODBC Support is enabled as well as pdo_sqlsrv support
Maybe you should try PDO (the performance difference isn't that great) with SQLsrv plugin (this what I'm using to connect to my other boss' software which use SQL Server 2008 database):
$connection = new PDO("sqlsrv:Server=" . $this->sourceServer . ";Database=" . $this->sourceDB, $this->sourceUser, $this->sourcePW);
$connection->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
You can download the plugin here
https://www.microsoft.com/en-ca/download/details.aspx?id=36434
In Xampp, you must copy the dll in that folder:
C:\xampp\php\ext
And you must add that line to your php.ini
extension = php_pdo_sqlsrv_56_ts.dll
Note: Don't forget to restart your server so it can take in account the new php.ini file.
Let me know if it works for you
This error is a General Error that arises due to unable to establish connect to the server for some reasons. Its important to know what server are you using with PHP and the application used with it. Example Apache, Xampp or Wamp etc.
Here are somethings you could try like.
Let me brief, below are the reference links.
Check whether it pings
Enable TCP/IP connection SQL Server Configuration if not enabled. To do so, Open SQL Server Configuration Manager -> SQL Server Network
Configuration->Protocols for SQL server->TCP/IP(set to enabled).
Restart SQL services.
Enable Remote Connection from server
Open the Port, To do so Windows Firewall Settings-> Exceptions -> add a Port (Name:SQL;Port:1433;TCP) then from Exceptions tick SQL and save.
Enable running browser services.SQL Server Configuration Manager -> SQL Server Services - > SQL Server Browser set to running.
defining Port in connection string
add instance name with machine name if more than one instance is being used
sample
$user = 'username';
$pass = 'password';
//Use the machine name and instance if multiple instances are used
$server = 'serverName\instanceName';
//Define Port
$port='Port=1433';
$database = 'database';
$connection_string = "DRIVER={ODBC Driver 11 for SQL Server};SERVER=$server;$port;DATABASE=$database";
$conn = odbc_connect($connection_string,$user,$pass);
here are useful links that i found regarding the issue

Have a look at these links too

Someone had the same error message and asked and answered his own question here.
To quote...
I´m sorry for the troubles.
The problem was, that I was using SQL Server Native Client 11.0 as driver. I switched it to SQL Server and now it works :/
Hopefully this at least helps someone, being in a similar problem....
A significant omission from your question is how you are running PHP and with which credentials.
Assuming you are using IIS or Apache (or another web server), then your PHP process is probably running under the local system account:
Since this account is local it doesn't have any authorisation to access your remote SQL Server.
You could alter the IIS/Apache service to run with the credentials (yours?) that are authorised to connect to SQL Server, but be aware this might cause other permissions issues with the service as well as being a problem if you change your password in the future.
Try running a test script from the command line (which should run with your credentials by default) to determine where the problem is:
php -r "var_dump(odbc_connect(...));"
Look at the regedit HKLM/SOFTWARE/ODBC
what is your folder name ?
If there is a "SQL Server Native Client 11.0" then you have to write your php code like
odbc_connect("Driver={SQL Server Native Client 11.0};Server=ip;Database=db;", "user", "pass");
However some of the server like server 2008 will be record this odbc like
ODBC Driver 11 for SQL Server
Then you have to replace SQL Server Native Client 11.0 by ODBC Driver 11 for SQL Server.
You have to create an ODBC interface first. In principle, this should also work without a user and pw. If defined in interface.
$pdo = new PDO('odbc:dsnName','user','pw');
Enable in IIS on Manager PHP o PDO_ODBC:
I have authenticated by Windows with following PHP statement:
$ Conn = new PDO ("odbc: Driver = {SQL Server}; Server = JAMILI-PC \ SQLEXPRESS; null; null");
I am using Windows 2008.
I hope it solves your problem.
