How to Enable Ad Hoc Distributed Queries

Expand your knowledge

Ad Hoc Distributed Queries can help you poll data from remote sources directly using OPENROWSET and OPENDATASOURCE. But remember, with great power comes great responsibility, because there are security implications at stake.

Confirm your server

Check if your SQL Server version supports Ad Hoc Distributed Queries. Although recent editions do, verification is crucial especially if you're part of the cool crowd still rocking older editions.

Debugging setup woes

Caught an error like "Msg 5808"? Add RECONFIGURE WITH OVERRIDE to your troubleshooting toolkit. After all, mistakes are just stepping stones to success.

Security comes first

Don't let excitement trump caution. Implement strict security measures to prevent ad hoc access for users who don't need it.

Digging deeper: Advanced configuration and common issues

Unleash the power of detailed control

Want a close-up look at your settings? Enable advanced options first:

-- "Alright SQL Server, no more hiding secrets!" 🕵️‍♂️
EXEC sp_configure 'show advanced options', 1; RECONFIGURE;


Once you've seen all, individual settings can be tailored to suit your needs.

Wrestling access issues

Hit an access roadblock? Squeeze in a chat with your system admin. Fiddling with SQL Server isn't much fun without the correct permissions, just like a secret club without the secret handshake.

Master the syntax

OPENROWSET isn't quite as welcoming as it sounds, especially with Trusted_Connection. Double-check the syntax before running it, lest SQL Server give you the silent treatment.

Override configuration, if needed

Sometimes, rules are meant to be broken. In extremely rare cases, RECONFIGURE WITH OVERRIDE can help you sidestep certain issue. But use it sparingly, it is SQL’s nuclear option.
