Context Functions (Session Object)

IS_ROLE_IN_SESSION

Returns TRUE if the current user’s active primary role or secondary roles in the session inherit the privileges of the specified role.

The specified role can be the current primary role or secondary role (i.e. the roles returned by CURRENT_ROLE or CURRENT_SECONDARY_ROLES, respectively) or any role lower in the role hierarchy.

When the DEFAULT_SECONDARY_ROLES value is ALL, the function returns TRUE if any role granted to the user inherits the privileges of the specified role.

Returns FALSE if the specified role is either higher in the role hierarchy of the current primary or secondary roles or is not in the role hierarchy at all.
