Error using views from other schema

Question

Hello,
i recently had problems using the execute immediate statement in Object Types.
The SQL statement tried to select from some views which were owned by an other schema.
Although we had public synonyms on these views and the same dynamic sql could be used out of a stored procedure the usage in the object type raised a "table or view does not exist exception".
using the same views in the same schema where the object types belonged to, was ok.
example:
schema: scott
view: my_view
schema: dave
sql: "select from scott.my.view ....."
works well from a stored procedure, but nor if used in an object type
create the view in schema "dave" an then
sql: "select from my.view ....."
works fine.
So is someone aware of this behaviour?
Is this a bug or a feature?
regards
peter

Hello Geoff,
here is the sample code.
If the table my_table belongs to the same
schema runningthe code the code runs with
no exception.
But if the table belongs to an other schema
(lets say SCOTT),
only having global synonyms and the rigths to
select on it, the code will raise an exception "table or view does not exist"
even if we use SCOTT.my_table in the
select.
create type query_o as object(
dummy integer,
static function get_query return
varchar2;
create or replace type body query_o as
static function get_query return varchar2
as
query varchar2(4000) :=
'select ' | |
' f.amount_month ' | |
'into :r1 ' | |
'from ' | |
' my_table f ' | |
'where id=:p1 ';
begin
return query;
end;
end;
create type consumer_o as object(
amount_month number,
member function find(p_id in integer)
return consumer_o
create type body consumer_o as
member function find(p_id in integer)
return consumer_o
as
l_amount number;
begin
execute immediate query_o.get_query()
using out l_amount,
in p_id;
return consumer_o( l_amount );
end;
end;
kind regards
