UltraLite does not support the deletion of users with Interactive SQL. However, you can delete users by:
Using Sybase Central to delete users from the User folder. See the procedure below for details.
Using the RevokeConnectFrom function on the Connection object to remove users from an UltraLite application.
Connect to the UltraLite database.
While browsing the database, click Users.
Right-click the user in the Users pane and click Delete.
