Question

I wrote a stored procedure to transfer data from one SQL server to another. Is it possible to have logic at the beginning of the stored procedure to only execute on a certain server?

For example:

If IP!="100.xxx.xxx.xxx" then
   RaiseError 'You cannot run this procedure from this server
end if

I know one solution is not deploy the proc to the other server. Just curious, thanks.

IF UPPER(@@SERVERNAME) = 'YOUR_SERVER'
BEGIN
    -- do stuff
END

Note that @@SERVERNAME may include the instance name information. So you can also say:

IF UPPER(@@SERVERNAME) = 'YOUR_SERVER\YOUR_INSTANCE'
BEGIN
    -- do stuff
END

If you only care about the server (and any instance on that server), you can use a different property, though this returns the node name not the virtual server name in the case of a clustered instance:

IF UPPER(SERVERPROPERTY('ComputerNamePhysicalNetBIOS')) = 'YOUR_SERVER'
BEGIN
    -- do stuff
END

If it’s clustered and you want the same code to prevent execution except on any instance in that cluster you can say:

IF UPPER(@@SERVERNAME) = 'YOUR_SERVER'
  OR UPPER(@@SERVERNAME) LIKE 'YOUR_SERVER\%'
BEGIN
    -- do stuff
END
