VIEW(7)							   SQL Commands 						     ALTER VIEW(7)

NAME

       ALTER VIEW - change the definition of a view

SYNOPSIS

       ALTER VIEW name ALTER [ COLUMN ] column SET DEFAULT expression
       ALTER VIEW name ALTER [ COLUMN ] column DROP DEFAULT
       ALTER VIEW name OWNER TO new_owner
       ALTER VIEW name RENAME TO new_name
       ALTER VIEW name SET SCHEMA new_schema

DESCRIPTION

       ALTER VIEW changes various auxiliary properties of a view. (If you want to modify the view's defining query, use CREATE OR REPLACE VIEW.)

       You  must  own the view to use ALTER VIEW.  To change a view's schema, you must also have CREATE privilege on the new schema.  To alter the
       owner, you must also be a direct or indirect member of the new owning role, and that role must have CREATE privilege on the view's  schema.
       (These  restrictions  enforce  that altering the owner doesn't do anything you couldn't do by dropping and recreating the view.	However, a
       superuser can alter ownership of any view anyway.)

PARAMETERS

       name   The name (optionally schema-qualified) of an existing view.

       SET/DROP DEFAULT
	      These forms set or remove the default value for a column.  A default value associated with a view column	is  inserted  into  INSERT
	      statements on the view before the view's ON INSERT rule is applied, if the INSERT does not specify a value for the column.

       new_owner
	      The user name of the new owner of the view.

       new_name
	      The new name for the view.

       new_schema
	      The new schema for the view.

NOTES

       For historical reasons, ALTER TABLE can be used with views too; but the only variants of ALTER TABLE that are allowed with views are equiv-
       alent to the ones shown above.

EXAMPLES

       To rename the view foo to bar:

       ALTER VIEW foo RENAME TO bar;

COMPATIBILITY

       ALTER VIEW is a PostgreSQL extension of the SQL standard.

NAME

       SQL::Translator::Parser::PostgreSQL - parser for PostgreSQL

SYNOPSIS

	 use SQL::Translator;
	 use SQL::Translator::Parser::PostgreSQL;

	 my $translator = SQL::Translator->new;
	 $translator->parser("SQL::Translator::Parser::PostgreSQL");

DESCRIPTION

       The grammar was started from the MySQL parsers.	Here is the description from PostgreSQL:

       Table: (http://www.postgresql.org/docs/view.php?version=7.3&idoc=1&file=sql-createtable.html)

	 CREATE [ [ LOCAL ] { TEMPORARY | TEMP } ] TABLE table_name (
	     { column_name data_type [ DEFAULT default_expr ]
		[ column_constraint [, ... ] ]
	     | table_constraint }  [, ... ]
	 )
	 [ INHERITS ( parent_table [, ... ] ) ]
	 [ WITH OIDS | WITHOUT OIDS ]

	 where column_constraint is:

	 [ CONSTRAINT constraint_name ]
	 { NOT NULL | NULL | UNIQUE | PRIMARY KEY |
	   CHECK (expression) |
	   REFERENCES reftable [ ( refcolumn ) ] [ MATCH FULL | MATCH PARTIAL ]
	     [ ON DELETE action ] [ ON UPDATE action ] }
	 [ DEFERRABLE | NOT DEFERRABLE ]
	 [ INITIALLY DEFERRED | INITIALLY IMMEDIATE ]

	 and table_constraint is:

	 [ CONSTRAINT constraint_name ]
	 { UNIQUE ( column_name [, ... ] ) |
	   PRIMARY KEY ( column_name [, ... ] ) |
	   CHECK ( expression ) |
	   FOREIGN KEY ( column_name [, ... ] )
	    REFERENCES reftable [ ( refcolumn [, ... ] ) ]
	     [ MATCH FULL | MATCH PARTIAL ]
	     [ ON DELETE action ] [ ON UPDATE action ] }
	 [ DEFERRABLE | NOT DEFERRABLE ]
	 [ INITIALLY DEFERRED | INITIALLY IMMEDIATE ]

       Index: (http://www.postgresql.org/docs/view.php?version=7.3&idoc=1&file=sql-createindex.html)

	 CREATE [ UNIQUE ] INDEX index_name ON table
	     [ USING acc_method ] ( column [ ops_name ] [, ...] )
	     [ WHERE predicate ]
	 CREATE [ UNIQUE ] INDEX index_name ON table
	     [ USING acc_method ] ( func_name( column [, ... ]) [ ops_name ] )
	     [ WHERE predicate ]

       Alter table:

	 ALTER TABLE [ ONLY ] table [ * ]
	     ADD [ COLUMN ] column type [ column_constraint [ ... ] ]
	 ALTER TABLE [ ONLY ] table [ * ]
	     ALTER [ COLUMN ] column { SET DEFAULT value | DROP DEFAULT }
	 ALTER TABLE [ ONLY ] table [ * ]
	     ALTER [ COLUMN ] column SET STATISTICS integer
	 ALTER TABLE [ ONLY ] table [ * ]
	     RENAME [ COLUMN ] column TO newcolumn
	 ALTER TABLE table
	     RENAME TO new_table
	 ALTER TABLE table
	     ADD table_constraint_definition
	 ALTER TABLE [ ONLY ] table
		 DROP CONSTRAINT constraint { RESTRICT | CASCADE }
	 ALTER TABLE table
		 OWNER TO new_owner

       View table:

	   CREATE [ OR REPLACE ] VIEW view [ ( column name list ) ] AS SELECT query
