DROP 
CAST(7)							   SQL Commands 						      DROP CAST(7)

NAME

       DROP CAST - remove a cast

SYNOPSIS

       DROP CAST [ IF EXISTS ] (sourcetype AS targettype) [ CASCADE | RESTRICT ]

DESCRIPTION

       DROP CAST removes a previously defined cast.

       To  be  able  to  drop a cast, you must own the source or the target data type. These are the same privileges that are required to create a
       cast.

PARAMETERS

       IF EXISTS
	      Do not throw an error if the cast does not exist. A notice is issued in this case.

       sourcetype
	      The name of the source data type of the cast.

       targettype
	      The name of the target data type of the cast.

       CASCADE

       RESTRICT
	      These key words do not have any effect, since there are no dependencies on casts.

EXAMPLES

       To drop the cast from type text to type int:

       DROP CAST (text AS int);

COMPATIBILITY

       The DROP CAST command conforms to the SQL standard.

DROP 
TABLE(7)							   SQL Commands 						     DROP TABLE(7)

NAME

       DROP TABLE - remove a table

SYNOPSIS

       DROP TABLE [ IF EXISTS ] name [, ...] [ CASCADE | RESTRICT ]

DESCRIPTION

       DROP  TABLE  removes tables from the database.  Only its owner can drop a table. To empty a table of rows without destroying the table, use
       DELETE [delete(7)] or TRUNCATE [truncate(7)].

       DROP TABLE always removes any indexes, rules, triggers, and constraints that exist for the target table.  However, to drop a table that	is
       referenced  by  a  view	or  a  foreign-key  constraint	of another table, CASCADE must be specified. (CASCADE will remove a dependent view
       entirely, but in the foreign-key case it will only remove the foreign-key constraint, not the other table entirely.)

PARAMETERS

       IF EXISTS
	      Do not throw an error if the table does not exist. A notice is issued in this case.

       name   The name (optionally schema-qualified) of the table to drop.

       CASCADE
	      Automatically drop objects that depend on the table (such as views).

       RESTRICT
	      Refuse to drop the table if any objects depend on it. This is the default.

EXAMPLES

       To destroy two tables, films and distributors:

       DROP TABLE films, distributors;

COMPATIBILITY

       This command conforms to the SQL standard, except that the standard only allows one table to be dropped per command, and apart from the	IF
       EXISTS option, which is a PostgreSQL extension.
