ORA-02070: database does not support in this context

问题

I'm trying to insert data from a VIEW in one DB to a table in another DB.

insert into schema.dummy_table@LINK 
SELECT v1.coulmn1, v1.cloumn2, v1.clolumn5, v1.cloumn7, v1.column3
 FROM user.view1 v1, user.view2 v2
        WHERE v1.column8 = v2.column1;

But this doesn't seem to work. I get

ORA-02070: database  does not support  in this context

Does that mean, this is not permitted on views?

回答1:

Based on names of the columns I guess that user.view1 or user.view2 selects data from one of system views like v$session.
Try to use gv$ views instead of v$ views.

This case already explained in this question on StackOverflow.

Source of such behavior is that where inst_id = USERENV('Instance') used in almost all v$-type views
