Hi,

I built a view ITEM_VIEW which gets records based on the user that queries it. I used user_name=sys_context('userenv','current_user')) in the where clause in the view. Now I have written a stored procedure in a generic(GENSCH) schema in which I am querying this view. I gave user1 and user2 permissions to execute the procedure. When I run the procedure GENSCH.procedure_name either using user1 or user2 it gives me all the records. I think it is running the view in the stored proc as user GENSCH rather than user1 or user2 irrespective of who I login as.

Please suggest how to accomplish this. I do not want to create local procedures for each user.

Let me know if you need more information with the query.

Thanks and Regards,
Veena

Use USER instead of SYS_CONTEXT:

SQL> create or replace procedure p is
  2    user1 varchar2(30) := sys_context('userenv','current_user');
  3    user2 varchar2(30) := user;
  4  begin
  5    dbms_output.put_line('sys_context='||user1||', user='||user2)
  6  end;
  7  /

Procedure created.

SQL> exec p;
sys_context=MICHEL, user=MICHEL

PL/SQL procedure successfully completed.

SQL> grant execute on p to test;

Grant succeeded.

SQL> connect test/test;
Connected.
TEST> exec michel.p
sys_context=MICHEL, user=TEST

PL/SQL procedure successfully completed.

Regards
Michel
