So if you have a situation where some DBs are on the old SQL Server and some DBs are on the new SQL Server, this won’t work. Keep in mind that any connection which leaves the client (web server) using this name will be redirected by the alias. The alias goes on whatever machine acts as the client. I tried the first way and it is not able to come up successfully. Is there any other way to create alias name for database restricted to particular query we are executing? To create a new alias, right-click onĪliases and choose New Alias. See any aliases that have been defined for the system shown in the right pane. The SQL Native Client Configuration folder, there is a subfolderĬalled Aliases (see Figure 1). In the left pane of SQL Server Configuration Manager, if you expand Let's start by looking at how to do it using SQL Server Configuration
You canĬreate an alias using one of two utilities: The alias is created, both will be re-pointed based on the alias. We have two applications which connect to MySQLServer on that computer, once Once an alias is created, it is set at the operating system level. The operating system to look somewhere else for the database. How can I do this easily without breaking other things that maybe using this connectionīy using an alias, we can keep the application configuration the same, but tell However, I need to move the database to a new server. I have an application that has a specified database connection that I eitherĬan't or don't want to change.

Then your connection string would be: Data Source = 127.2. Configure the modem to forward port 1433 to 192.168.0.100:1433 (how will depend on make and model of modem).
Let's say you have an ADSL modem listening on 127.2.3.4 (invalid address for demonstration only) and a PC behind that with an IP address of 192.168.0.100.
This must be done on the modem, and cannot be done just with a connection string. If you are trying to connect to a home computer behind an ADSL modem with a static IP address, your ADSL modem needs to be configured with port forwarding to connect the external port 1433 with the same port on the internal address. If the database you are trying to connect to is on a computer behind a that has the target address, you will need to use port forwarding on the to forward all connections on TCP port 1433 through to the target machine. I am trying to connect outside the building.
