.TH "DROP TABLE" SQL 11/05/95 Postgres95 Postgres95
|
|
.SH NAME
|
|
drop table \(em destroy existing classes
|
|
.SH SYNOPSIS
|
|
.nf
|
|
\fBdrop table\fR classname-1 { \fB,\fR classname-i }
|
|
.fi
|
|
.SH DESCRIPTION
|
|
.BR "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
|
|
.IR delete (l).
|
|
.PP
|
|
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.
|
|
.PP
|
|
The destruction of classes is not reversable. 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.
