Drop user-defined, user-extended, and compatibility roles. You cannot drop system roles.
You must have administrative rights for the role being dropped.
The role being dropped must not own any database objects.
You can only drop a role if all dependent roles meet the minimum required number of administrative users with active passwords, as set by the min_role_admins database option.
In Sybase Central, use the SQL Anywhere 16 plug-in to connect to the database.
Double-click Roles and select the role you want to drop.
Right-click the role and click Delete.
