DROP ROUTE (Transact-SQL)
Applies To: SQL Server 2014, SQL Server 2016 Preview
Drops a route, deleting the information for the route from the routing table of the current database.
Applies to: SQL Server (SQL Server 2008 through current version).
The name of the route to drop. Server, database, and schema names cannot be specified.
The routing table that stores the routes is a metadata table that can be read through the catalog view sys.routes. The routing table can only be updated through the CREATE ROUTE, ALTER ROUTE, and DROP ROUTE statements.
You can drop a route regardless of whether any conversations use the route. However, if there is no other route to the remote service, messages for those conversations will remain in the transmission queue until a route to the remote service is created or the conversation times out.
Permission for dropping a route defaults to the owner of the route, members of the db_ddladmin or db_owner fixed database roles, and members of the sysadmin fixed server role.
