Default Map for the User, Database, or Profile

The immediate owner of the join index can be a user or a database. See the CREATE USER DEFAULT MAP option, the MODIFY USER DEFAULT MAP option, the CREATE DATABASE DEFAULT MAP option, the MODIFY DATABASE DEFAULT MAP option, the CREATE PROFILE DEFAULT MAP option, or the MODIFY PROFILE DEFAULT MAP option.

User, Database, or Profile DEFAULT MAP OVERRIDE ON ERROR Option

If the map you specify is not valid for any reason, (such as it does not exist, has not been granted to you, or is not in the same secure zone), Vantage either substitutes a default map or returns an error, subject to the values of the DEFAULT MAP settings for your PROFILE, USER, or DATABASE.

Default Map for a CREATE JOIN INDEX Statement

If you do not specify the MAP option when creating a join index, the system determines a default map for the join index in the following order of precedence:
  • If the immediate owner is not the creator:
    • Default map, if defined, for the profile of the immediate owner.
    • Default map, if defined, for the immediate owner.
    • System-default map.
  • Default map, if defined, for the profile of the creator.
  • Default map, if defined, for the creator.
  • System-default map.

Secure Zones and Sparse Maps

For a sparse map, you must be in the same secure zone as the sparse map.
