alter database

Adaptive Server 15.7 SP100 includes changes to the alter database command.

off

alter database allows you to shrink databases, and adds the off parameter, which specifies the device names from which you are releasing space. The syntax is:
alter database database_name
. . . 
     off database_device {=size  | [from page_number] [to page_number]}
     [, database_device…]
     [with timeout='time']
