django-db2 use different schema name than database username
DB2 uses so-called two part names, schemaname.objectname. Each object, including tables, can be referenced by the entire name. Within a session there is the current schema which by default is set to the username. It can be changed by the SET SCHEMA myschema statement. 
For your question there are two options:
1) Reference the tables with their full name: schemaname.tablename
2) Use set schema to set the common schemaname and reference just the table.
In Django database username is used as schema name.
In DB2 there is no database level users. OS users will be used for login into the database.
In my database I have two different names for database user and database schema.
So in django with db2 as backend how can I use different schema name to access the tables?
EDIT:
Clarifying that I'm trying to access via the ORM and not raw SQLs. The ORM implicitly is using the username as the schema name. How do I avoid that ?
