I have a linkedserver that will change. Some procedures call the linked server like this: [10.10.100.50].dbo.SPROCEDURE_EXAMPLE
. We have triggers also doing thi
I've used these in the past:
In this particular case, where you need to replace a specific string across stored procedures, the first link is probably more relevant.
A little off-topic, the Quick Find add-in is also useful for searching object names with SQL Server Management Studio. There's a modified version available with some improvements, and another newer version also available on Codeplex with some other useful add-ins as well.
There are much better solutions than modifying the text of your stored procedures, functions, and views each time the linked server changes. Here are some options:
Update the linked server. Instead of using a linked server named with its IP address, create a new linked server with the name of the resource such as Finance
or DataLinkProd
or some such. Then when you need to change which server is reached, update the linked server to point to the new server (or drop it and recreate it).
While unfortunately you cannot create synonyms for linked servers or schemas, you CAN make synonyms for objects that are located on linked servers. For example, your procedure [10.10.100.50].dbo.SPROCEDURE_EXAMPLE
could by aliased. Perhaps create a schema datalinkprod
, then CREATE SYNONYM datalinkprod.dbo_SPROCEDURE_EXAMPLE FOR [10.10.100.50].dbo.SPROCEDURE_EXAMPLE;
. Then, write a stored procedure that accepts a linked server name, which queries all the potential objects from the remote database and (re)creates synonyms for them. All your SPs and functions get rewritten just once to use the synonym names starting with datalinkprod
, and ever after that, to change from one linked server to another you just do EXEC dbo.SwitchLinkedServer '[10.10.100.51]';
and in a fraction of a second you're using a different linked server.
There may be even more options. I highly recommend using the superior techniques of pre-processing, configuration, or indirection rather than changing human-written scripts. Automatically updating machine-created scripts is fine, this is preprocessing. Doing things manually is awful.

You can search within the definitions of all database objects using the following SQL:
SELECT
o.name,
o.id,
c.text,
o.type
FROM
sysobjects o
RIGHT JOIN syscomments c
ON o.id = c.id
WHERE
c.text like '%text_to_find%'
