I would like to find all references to linked servers in stored procedures /functions/views. Ideally this would be done for all database on a server. We have a number hardcoded references (i.e. ServerA.NorthWind.dbo.Employees) and would perfer to use SQL aliases so we can migrate code easily.
The following code finds most references by searching for ".dbo." but it doesnt filter out commets. Does someone else have a better solution?
set quoted_identifier off
exec SP_MSFOREACHDB "
select '?' , name, sysobjects.xtype, SUBSTRING(TEXT,PATINDEX('%.dbo.%',TEXT) ,100)
from [?].dbo.sysobjects sysobjects join [?].dbo.syscomments syscomments on sysobjects.id = syscomments.id
where text like '%.dbo.%'"

this is just a prototype for a single database, but it's easily adaptable i think.

I'm assuming that the current server has all the linked servers....so I thought why not search for the actual linked server name? ie "MACHINENAME\SQLEXPRESS" or whatever...to make it more specific, you could add a period to search for 'linkedserver.' instead of 'linkedserver'

It worked on a new proc i created just fine.

declare @LinkedServers table(

SRV_NAME varchar(128),

SRV_PROVIDERNAME varchar(128),

SRV_PRODUCT varchar(128),

SRV_DATASOURCE varchar(128),

SRV_PRIVIDERSTRING varchar(128),

SRV_LLOCATION varchar(128),

SRV_CAT varchar(128)

)

INSERT INTO @LinkedServers

EXEC sp_linkedservers

SELECT SRV_NAME FROM @LinkedServers

select *

from syscomments cross join @LinkedServers x

where charindex(x.SRV_NAME,syscomments.TEXT) > 1

Unfortunately I'm still on SQL 2000 so I get the following error:

Server: Msg 197, Level 15, State 1, Line 12

EXECUTE cannot be used as a source when inserting into a table variable.

just change to a temp table, no problem:

CREATE TABLE #LinkedServers (
