The DROP GROUP statement removes the definition of an authorization
group from the system catalog.
Example | 
  | 
   CREATE GROUP Warehse
   GRANT CONNECT TO Warehse
   GRANT SELECT,
         UPDATE (BinNumber,QtyOnHand,LastCountDate)
      ON PurchDB.Inventory
      TO Warehse
 | 
These two users will be able to start DBE sessions, retrieve data from table PurchDB.Inventory, and update three columns in the table.
   ADD CLEM@THOMAS, GEORGE@CRAMMER TO GROUP Warehse
  | 
Clem no longer has any of the authorities associated with group Warehse.
   REMOVE CLEM@THOMAS FROM GROUP Warehse
  | 
Because this group does not own any database objects, it can be deleted. George no longer has any of the authorities once associated with the group.
