Did you mean ALTER VIEW Viewname instead of ALTER TABLE Viewname?

Hi Vincenzo,
There is no option like disable rule in alter view documentation.
Still after trying it, it gives same error as follows.

ERROR:  "viewname" is not a table

Thanks,

Shashwat.

Hi all,
I am using postgres 9.3.4 and have an on_select rule "_return" on a view.
I want to drop or disable or bypass that rule.
Is there any way it can be done without dropping the view??

Because when i try to drop it, it returns

ERROR:  cannot drop rule _RETURN on view viewname because view viewname requires it
HINT:  You can drop viewname instead.
CONTEXT:  SQL statement "drop rule "_RETURN" on viewname"
PL/pgSQL function inline_code_block line 12 at EXECUTE statement

and i don't want to drop the view.

when i try to disable it using :
alter table viewname disable rule _return
it returns
ERROR:  "viewname" is not a table


Bypassing rule for a single query or disabling it for some time and then enable it will also work for me.

Can it be done ?

Thanks,
Shashwat.

 

Hi Shashwat

I am no PG guru but I guess that, since "viewname" is a view and not a table, you should use "alter view" and not "alter table". See:
http://www.postgresql.org/docs/9.3/static/sql-alterview.html
