Hai all,
I need a solution to retrive a data from one server from another server. I need to put a simple direct select statement for this(no stored procedures allowed).
ex: Select * From server1.DB1.dbo.Table1
I give a linked server connection to the respective servers. What i need is that in the above qry i need to provide a server name common. Like it may be in the form of variables.
ex:
Declare @server Varchar(25)
@server = ServerName1
Select * From @server.DB1.dbo.Table1
I know the above qry doesn't work but i need a equivalent on this.
Thanks,
Mano Karnan

You could use dynamic SQL like:

DECLARE @query NVARCHAR(4000)

SET @query = 'Select * From ' + @server + '.DB1.dbo.Table1 '

EXECUTE ( @query )

I want to use the mixed server query. That is

Select * From server1.DB1.dbo.Table1 a , server2.DB2.dbo.Table2 b

Where a. no = b.no

something like the above. The query may be too long to write. I think that the given solution may be very complicated for me to write. I have more number of queries to write and i go create a task in SSIS and make to run it. I need some other solution needed if possible. Just i want to know this is the only solution for this. Any idea????

Thanks,

Mano Karnan

You are correct... things are going to get a little complex because you need a query to build a dynamic query from Master.dbo.SysServers.

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.
