How can I indicate the port in a SQL Server 2005 OLE DB connection string?

I recently discovered a solution and decided to share it. Instead of using a colon, use a comma to separate the IP address from the port number. This approach is essential for named instances, as the port must be specified even if it is the default 1433.

Example:

Provider=SQLServerOLEDB;Data Source=10.20.30.40,1433;Initial Catalog=SalesDB;User Id=SalesUser;Password=SafePass;

hey, i had the same issue, and found that using a commma instead of a colon does the trick. its not very intuitive but works for both default and named isntances

Based on extensive experience managing SQL Server environments, separating the IP address and port using a comma has proven to be a reliable solution for establishing OLE DB connections in SQL Server 2005. In my case, ensuring that the connection string adhered to this syntax eliminated intermittent connection issues, especially when dealing with named instances. I also observed that proper configuration and verifying that the port is open on the server are essential steps in troubleshooting connection problems. Adopting this method has consistently resulted in stable connections during both development and production scenarios.

hey, i’ve been using the comma for specifying ports too. its weird but effective. have any of you tried any alternate methods or noticed different behaviors in various environments? i’m curious abt others experiences

hey, i’ve used the comma approach and it’s been pretty reliable. sometimes though, misconfigured firewalls can mess things up, so double-check that. it might seem odd, but it’s the only way to get the port recognized without extra hassle.

In my experience, ensuring proper connectivity with SQL Server 2005 through OLE DB required careful attention to the syntax used in the connection string. The comma approach has always been effective, particularly when working with named instances or non-default ports. Over time, I confirmed that this method not only prevents syntax errors but also avoids unexpected connection failures that can occur with alternative delimiters. It is also important to verify that firewall settings and network configurations align with the specified port for uninterrupted access.
