Question

Is it possible to do

alter session set current_schema=MySchema;

inside a package?

Our asp.net web application call Oracle packages. We’d like to connect to database with an Oracle user that is not the owner of MySchema. For that, we grant execute permissions on Other_User to package MyPackage.

Example:

grant execute on MySchema.MyPackage to Other_User

But when web app connects to Oracle and try to execute the stored procedures of MyPackage, it gets errors because tables don’t belong to Other_User.

One way to avoid errors is creating synonyms, but we would prefere to use

alter session set current_schema=MySchema;

if possible, inside the package.

EDIT: When trying to put “alter session” in package:

Answer 1

You cannot use DDL statements (which ALTER SESSION is) directly in PL/SQL.

You need to use an EXECUTE IMMEDIATE:

execute immediate 'alter session set current_schema=MySchema';
