Alter Filter
Add filter rows to a database security filter. Filters control security for database objects. Use grant to assign filters to users and groups.
Minimum permission required: Database Manager.
Syntax
Use alter filter in the following ways to edit a filter:
| Keyword | Description |
|---|---|
alter filter ...add no_access on <member-expression> | Block access to a specified member combination. |
alter filter ... add read on <member-expression> | Provide read-only access to a specified member combination. |
alter filter ... add write on <member-expression> | Provide write access to a specified member combination. |
alter filter ... add meta_read on <member-expression> | Restrict access to siblings and ancestors of the member expression. In case of a filtering conflict, the MetaRead filtering overrides the other filter permissions. For more information about metatdata filtering, see Metadata Filtering. |
