Dynamic SQL execution on remote SQL Server using EXEC AT

 

Problem
With SQL Server 2000, we had OPENQUERY and OPENROWSET to execute a pass-through query on the specified server, but it has several inherent limitations. Starting with SQL Server 2005 we have another more elegant way using "EXEC AT" to execute a pass-through query on the specified linked server which also addresses several shortcomings of OPENQUERY and OPENROWSET table functions.

In this tip I am going to start my brief discussion with OPENQUERY and OPENROWSET table functions, its limitation and how the new EXEC AT command overcomes them.
