Specifies the name of the client application connecting to SQL Server.

Data Type

string

Default Value

""

Remarks

This property sets the application name that is sent to the server as part of the connection metadata. On SQL Server, this value is typically visible in monitoring or logging tools and can be helpful for identifying, auditing, or troubleshooting specific application connections.

While this value is not strictly required for the connection, setting a unique application name is a good practice when multiple apps or services access the same database.

This property is useful for environments where SQL Server administrators monitor or analyze incoming connections, as it helps distinguish one application from another.

Additional Information

This value is also used as the User-Agent when HTTP-based communication is involved, such as through web proxies or gateways that inspect headers.
