SQL Report From Another Schema

Question

Is there anyway to select a table from another schema?I have a default schema for my application but i want each user to use their own schema.
I'm looking for something like #OWNER#.table_name but replacing #OWNER# with the name of another schema in the workspace.
Kind Regards,

Hello BgUrsea,
you could achieve this by granting the needed privileges (e.g. select, insert, update, delete) on each table in the #OWNER#-schema to your applications parsing schema.
If you can't use a direct mapping (e.g., you can't assign the schema name of a user as usernames for his application user), you probably need a mapping table in your parsing schema. Define an application item (e.g. "F_OWNER") and create a application computation that executes "On New Instance" and does something like
SELECT schema
  FROM mapping_table
WHERE owner=v('APP_USER');If you aren't sure you always have a mapping, you might think about an application process that not only computes the value but also handles the action to be performed in case there is no mapping for a user.
But I suppose it could be easier to have a copy of you application for each user and assign the appropriate schema to each copy. That way, you don't need the mapping, you don't need to care about always using the #OWNER# when developing your application, and of course, no user can (not even accidently) access another users (or your default) schema.
