NAME

       CREATE TABLE AS - create a new table from the results of a query

SYNOPSIS

       CREATE [ [ LOCAL ] { TEMPORARY | TEMP } ] TABLE table_name [ (column_name [, ...] ) ]
	   AS query

DESCRIPTION

       CREATE  TABLE AS creates a table and fills it with data computed by a SELECT command. The table columns have the names and data types asso-
       ciated with the output columns of the SELECT (except that you can override the column names by  giving  an  explicit  list  of  new  column
       names).

       CREATE TABLE AS bears some resemblance to creating a view, but it is really quite different: it creates a new table and evaluates the query
       just once to fill the new table initially. The new table will not track subsequent changes to the source tables of the query. In  contrast,
       a view re-evaluates its defining SELECT statement whenever it is queried.

PARAMETERS

       [LOCAL] TEMPORARY or [LOCAL] TEMP
	      If specified, the table is created as a temporary table.	Refer to CREATE TABLE [create_table(7)] for details.

       table_name
	      The name (optionally schema-qualified) of the table to be created.

       column_name
	      The  name of a column in the new table. Multiple column names can be specified using a comma-delimited list of column names. If col-
	      umn names are not provided, they are taken from the output column names of the query.

       query  A query statement (that is, a SELECT command). Refer to SELECT [select(7)] for a description of the allowed syntax.

DIAGNOSTICS

       Refer to CREATE TABLE [create_table(7)] and SELECT [select(7)] for a summary of possible output messages.

NOTES

       This command is functionally equivalent to SELECT INTO [select_into(7)], but it is preferred since it is less likely to	be  confused  with
       other uses of the SELECT ... INTO syntax.

COMPATIBILITY

       This  command  is modeled after an Oracle feature. There is no command with equivalent functionality in SQL92 or SQL99. However, a combina-
       tion of CREATE TABLE and INSERT ... SELECT can accomplish the same thing with little more effort.

HISTORY

       The CREATE TABLE AS command has been available since PostgreSQL 6.3.

NAME

       CREATE_FOREIGN_TABLE - define a new foreign table

SYNOPSIS

       CREATE FOREIGN TABLE [ IF NOT EXISTS ] table_name ( [
	 { column_name data_type [ OPTIONS ( option 'value' [, ... ] ) ] [ NULL | NOT NULL ] }
	   [, ... ]
       ] )
	 SERVER server_name
       [ OPTIONS ( option 'value' [, ... ] ) ]

DESCRIPTION

       CREATE FOREIGN TABLE will create a new foreign table in the current database. The table will be owned by the user issuing the command.

       If a schema name is given (for example, CREATE FOREIGN TABLE myschema.mytable ...) then the table is created in the specified schema.
       Otherwise it is created in the current schema. The name of the foreign table must be distinct from the name of any other foreign table,
       table, sequence, index, or view in the same schema.

       CREATE FOREIGN TABLE also automatically creates a data type that represents the composite type corresponding to one row of the foreign
       table. Therefore, foreign tables cannot have the same name as any existing data type in the same schema.

       To be able to create a table, you must have USAGE privilege on all column types.

PARAMETERS

       IF NOT EXISTS
	   Do not throw an error if a relation with the same name already exists. A notice is issued in this case. Note that there is no guarantee
	   that the existing relation is anything like the one that would have been created.

       table_name
	   The name (optionally schema-qualified) of the table to be created.

       column_name
	   The name of a column to be created in the new table.

       data_type
	   The data type of the column. This can include array specifiers. For more information on the data types supported by PostgreSQL, refer
	   to Chapter 8, Data Types, in the documentation.

       NOT NULL
	   The column is not allowed to contain null values.

       NULL
	   The column is allowed to contain null values. This is the default.

	   This clause is only provided for compatibility with non-standard SQL databases. Its use is discouraged in new applications.

       server_name
	   The name of an existing server for the foreign table.

       OPTIONS ( option 'value' [, ...] )
	   Options to be associated with the new foreign table or one of its columns. The allowed option names and values are specific to each
	   foreign data wrapper and are validated using the foreign-data wrapper's validator function. Duplicate option names are not allowed
	   (although it's OK for a table option and a column option to have the same name).

EXAMPLES

       Create foreign table films with film_server:

	   CREATE FOREIGN TABLE films (
	       code	   char(5) NOT NULL,
	       title	   varchar(40) NOT NULL,
	       did	   integer NOT NULL,
	       date_prod   date,
	       kind	   varchar(10),
	       len	   interval hour to minute
	   )
	   SERVER film_server;

COMPATIBILITY

       The CREATE FOREIGN TABLE command largely conforms to the SQL standard; however, much as with CREATE TABLE, NULL constraints and zero-column
       foreign tables are permitted.
