Calling Table-Valued Functions through Linked Server

Calling Table-Valued Functions through Linked Server

In the intricate realm of SQL Server, linked servers stand as bridges connecting different data sources. Sometimes, we need to tap into these connections to call table-valued functions residing in remote databases. In this guide, we’ll dive into the practical world of OPENQUERY and OPENROWSET, unlocking the ability to access remote data while sprinkling in a touch of lightheartedness and addressing common IT murmurs.

1. Calling Table-Valued Functions:

Using OPENQUERY:

SELECT *
FROM OPENQUERY(LinkedServerName, 'SELECT * FROM RemoteDatabaseName.dbo.FunctionName(parameters)')

Using OPENROWSET:

SELECT *
FROM OPENROWSET('SQLNCLI', 'Server=LinkedServerName;Trusted_Connection=yes;',
'SELECT * FROM RemoteDatabaseName.dbo.FunctionName(parameters)')

Using Exec Statement:

exec ('
select *
FROM RemoteDatabaseName.dbo.FunctionName(parameters))
') at [LinkedServerName]

Replace:

• LinkedServerName with the linked server’s name.
• RemoteDatabaseName with the remote database housing the function.
• FunctionName with the function, you wish to call.
• parameters with any required parameters for the function.

In the intricate world of IT, quirks and uncertainties are as common as finding a coffee machine in an office. For quick guidance, the wise counsel of Slack and diligent error message interpretation often prove invaluable.

Congratulations! You’ve successfully navigated the linked server terrain, summoned table-valued functions, and perhaps even shared a chuckle amidst the data. Just remember, in the realm of IT, a bit of humor and adaptability can go a long way. Now, set forth, gather your data treasures, and let your SQL escapades be a blend of expertise, cheer, and a splash of real-world tech tales!
