Server=.\SQLEXPRESS Database=MyDatabase User ID=MyUser Password=MyPasswordīut when my application went for testing, and it needed to connect to an SQL Server 2016 Express instance to a computer located on my LAN with the following connection string. There was no problem connecting to the local instance of SQL Server 2016 Express using standard SQL Server connection string: I was developing a C# WPF desktop application that connects to the local instance of SQL Server 2016 Express. So, I decided to document the process here for my own documentation, and for others who would like to do the same thing.
But, despite reading those while configuring it myself, I still hit some errors that need minutes or hours to resolve. I’m sure there are many guides out there on this topic already. Here is the reference for SQL Server JDBC connection string.In this article, I will share my experience about configuring SQL Server 2016 Express on LAN for SQL connection using my C# application’s connection string. In this case, those values are defined in the boxes below. In this example, the url string is jdbc:sqlserver://localhost\SQLEXPRESS:52188 You can add username and password in the string. To enable user login with SQL Server Express, refer to the previous post How to Enable User Login with SQL Server Express. With integratedSecurity=true, you may get the error: the driver is not configured for integrated authentication. You need to make sure SQL server enables password login. If this is set to 52188, make sure to add port number in the JDBC connection string. You can either set it to 1433 or keep it as 52188. The default port number for SQL Server Express is different from the default port for SQL Server, which is 1433. Make sure the server is not using dynamic port. Once you enable it, you need to restart the server.įrom the TCP/IP Properties above, go to the IP Address tab and scroll down to the bottom. Go to Sql Server Configuration Manager (usually located in C:\\Windows\SysWOW64) and enable TCP protocol if it is not enabled. In this demo, I am using SQL Workbench to connect to the server. Once you install SQL Server Express locally, you need to go through a few configuration steps to connect to the server with JDBC.
