drop table - destroy existing classes
drop table classname-1
{ , classname-i }
Drop Table removes classes from the data
base. Only its owner may destroy a class. A class may be emptied of instances,
but not destroyed, by using delete(l)
.
If a class being destroyed has
secondary indices on it, then they will be removed first. The removal
of just a secondary index will not affect the indexed class.
The destruction
of classes is not reversible. Thus, a destroyed class will not be recovered
if a transaction which destroys this class fails to commit. In addition,
historical access to instances in a destroyed class is not possible.
