SQL with Manoj

 
Today while executing a Stored Procedure which internally executes a remote query via Linked Server, I got following error:

Msg 50000, Level 16, State 127, Procedure spExecureRemoteQuery, Line 50

SQL Server blocked access to STATEMENT ‘OpenRowset/OpenDatasource’ of component ‘Ad Hoc Distributed Queries’ because this component is turned off as part of the security configuration for this server. A system administrator can enable the use of ‘Ad Hoc Distributed Queries’ by using sp_configure. For more information about enabling ‘Ad Hoc Distributed Queries’, search for ‘Ad Hoc Distributed Queries’ in SQL Server Books Online.

The above clearly means that the “Ad Hoc Distributed Queries” option is disabled on the database instance.

–> Run below Query to check if this property is disabled, if will show you 0 value under Config & Run value columns:

sp_configure 'show advanced options', 1
GO
EXEC sp_configure
GO

–> To enable it run the below Query:

sp_configure 'Ad Hoc Distributed Queries', 1
GO
RECONFIGURE WITH OverRide
GO
EXEC sp_configure
GO

…the value under Config & Run value columns shows 1, means that now the Property is enabled and you can execute your Remote/Linked-Server queries.
