Hi guys,

In the 12.2 PL/SQL Language Reference it says that 
PRAGMA RESTRICT_REFERENCES
is deprecated.
http://docs.oracle.com/database/122/LNPLS/RESTRICT_REFERENCES-pragma.htm#LNPLS01339

In the 12.2 Data Cartridge Developers Guide they state that I "must" restrict the references so the SQL engine knows the purity level of the functions.
http://docs.oracle.com/database/122/ADDCI/implementing-data-cartridges-in-PL-SQL.htm#ADDCI4321

So is it safe to say I should be using RESTRICT_REFERENCES with data cartridges but not elsewhere?

Thanks for your help!

My *understanding* is that you should not be using it *anywhere*, but I'll file a request with the doc team, and follow up whether its a doc bug or a genuine requirement for the cartridges, and update this when I get some more info.

Apologies - I should updated this post.

The 18c documentation has been updated to remove the need/reference to the pragma.
