NAME

drop table - destroy existing classes

SYNOPSIS

drop table classname-1 { , classname-i }

DESCRIPTION

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.

EXAMPLE

--
--Destroy the emp class
--
drop table emp
--
--Destroy the emp and parts classes
--
drop table emp, parts
