Windows 10: Why is my workstation trying to find the SQL server on the wrong port?

Jim W4 · Jul 17, 2023

I have an application configured through SQLExpress 2012, which is configured to listen on tcp 1433 as the default.Lately, we have desktop clients getting weird error messages trying to login to the app Operation not allowed when the object is closed and the one thing I've noticed about these workstations is that they are trying to connect on tcp 1434 instead of 1433. Is there a way to change the client to connect to the correct port? Or, more broadly, why does this behavior suddenly change when most workstations were doing the correct thing and attempting to connect on 1433 until some tim

SQL Server + C#: What’s new

With the release of SQL Server v.Next public preview on Linux and Windows, the ability to connect to SQL Server on Linux, Windows, Docker or macOS (via Docker) makes cross-platform support for all connectors, including .NET Framework and .NET Core SqlClient, even more important. To enable C# developers to use the newest SQL Server features, we have been updating SqlClient with client-side support for new features.

In .NET Framework, we have provided client-side support for Always Encrypted and added Azure Active Directory as an authentication method. We’ve also added a new connection string parameter called “Pool Blocking Period.” It can be used to select the behavior of the blocking period when connecting to Azure SQL Database and SQL Server. Many applications that connect to Azure SQL Database need to render quickly, and the exponential blocking period can be problematic, especially when throwing errors. By adding the Pool Blocking Period parameter, we aim to improve the experience for connections to Azure SQL Database. Learn more about the new parameter here.

.NET Core is the cross-platform, open-source implementation of the .NET Framework. The project includes CoreFX, the foundational libraries of .NET Core. Cross-platform support allows developers to seamlessly run applications on their operating system of choice, regardless of the platform it was developed on. For example, an app developed on Windows can be deployed to macOS and Linux, without ever having to port any code. To connect apps written in .NET Core to SQL Server (hosted anywhere), developers can use System.Data.SqlClient available in CoreFX. By developing in .NET Core on GitHub, we have been able to get feedback quickly and are actively working to enable the breadth of application scenarios and workloads.

SQL Server + Python — What’s new

Python is one of the most popular and fastest-growing languages used today. Pyodbc (Python-SQL Server Connector) is an open source Python module maintained by Michael Kleehammer that uses ODBC Drivers to connect to SQL Server. It allows you to connect from the platform of your choice to SQL Server on-premises and in the cloud. Pyodbc is also cross platform and can be installed using pip.

We recently announced SQL Server v.Next CTP1 on Linux and Windows, which brings the power of SQL Server to both Windows and — for the first time ever — Linux. You can now connect your applications to SQL Server running on Linux, Windows and macOS (with Docker).

For our Python developers, we have a few updates that will improve Python connectivity with SQL Server. Pyodbc is now:

Officially supported: You can contact Microsoft Customer Service and Support (CSS) via phone, email, Twitter, forums, etc., to report and get help with any issue.

Available in Jupyter Notebooks for SQL Server: The Jupyter Notebook is a web application that allows you to create and share documents that contain live code, equations and visualizations.Pyodbc and its dependencies ship out of the box with Juypter notebooks on Azure. To get started, go to notebooks.azure.com and create a new Python 2 notebook or follow the instructions here. Check out the code sample and paste it in your notebook’s interactive prompt to get started.

Compatible with Python 3.5 and Django 1.10 through Django-pyodbc-azure.

SQL Server + PHP – What’s new

PHP is one of the most widely used programming languages for web developers today. The Microsoft PHP Connector for SQL Server is used to connect PHP applications to SQL Server, whether SQL Server is hosted in the cloud, on-premises or provided as a platform as a service.

We recently announced SQL Server v.Next CTP1 on Linux and Windows, which brings the power of SQL Server to both Windows and — for the first time ever — Linux. Developers can now create applications with SQL Server on Linux, Windows, Docker or macOS (via Docker) and then deploy to Linux, Windows, or Docker, on-premises or in the cloud.

As part of this announcement, we have made some improvements to our PHP connector:

SQL Server v.Next Support: You can now use the PHP connectors to connect to SQL Server v.Next CTP1 of SQL Server running anywhere, including SQL Server on Linux, Windows or Docker.

Linux support: We’ve created Linux-native versions of sqlsrv and pdo_sqlsrv modules of the PHP SQL Server Connector. Now you can use the PHP Connector to connect to SQL Server on Ubuntu 15.04, 15.10, 16.04, Red Hat 6 and Red Hat 7.

PHP 7.0 and 7.1 support: We have added support for the latest PHP runtimes for Windows and Linux with our releases on GitHub.

PECL Install Experience for Linux: We have created native PECL packages for Linux. This enables developers to install, upgrade and uninstall the PHP SQL Server connector using the PECL package repository. This is explained in detail in our Getting Started tutorials.

Community input for prioritization: We have also started using surveys on GitHub to guide our prioritization for features and improvements. Check our latest survey and let us know what you think.

Get started today

Check out the PHP connector source code on GitHub and our packages (sqlsrv, pdo_sqlsrv) on PECL. Make pull requests and let us know what you think.
