You can drop an index when it is no longer needed, or when you need to modify the definition of a column that is part of a primary or foreign key.
You must have DBA authority or be the owner of the table on which the index is created.
Context and remarks
Use the SQL Anywhere 12 plug-in to connect to the database.
In the left pane, double-click Indexes.
