NAME
       INSERT - create new rows in a table


SYNOPSIS
       INSERT INTO table [ ( column [, ...] ) ]
	   { DEFAULT VALUES | VALUES ( { expression | DEFAULT } [, ...] ) | query }


DESCRIPTION
       INSERT  allows  one  to insert new rows into a table. One can insert a
       single row at a time or several rows as a result of a query.

       The columns in the target list may be listed in any order.  Each	 col-
       umn  not	 present  in the target list will be inserted using a default
       value, either its declared default value or null.

       If the expression for each column is not of  the	 correct  data	type,
       automatic type conversion will be attempted.

       You  must have INSERT privilege to a table in order to insert into it.
       If you use the query clause to insert rows from a query, you also need
       to have SELECT privilege on any table used in the query.

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

       column The name of a column in table.

       DEFAULT VALUES
	      All columns will be filled with their default values.

       expression
	      An expression or value to assign to column.

       DEFAULT
	      This column will be filled with its default value.

       query  A	 query	(SELECT	 statement)  that  supplies  the  rows	to be
	      inserted. Refer to the SELECT statement for  a  description  of
	      the syntax.

OUTPUTS
       On  successful  completion, an INSERT command returns a command tag of
       the form

       INSERT oid count

       The count is the number of rows inserted. If count is exactly one, and
       the  target  table  has	OIDs,  then  oid  is  the OID assigned to the
       inserted row. Otherwise oid is zero.

EXAMPLES
       Insert a single row into table films:

       INSERT INTO films VALUES
	   (’UA502’, ’Bananas’, 105, ’1971-07-13’, ’Comedy’, ’82 minutes’);


       In this second example, the last column len is omitted  and  therefore
       it will have the default value of null:

       INSERT INTO films (code, title, did, date_prod, kind)
	   VALUES (’T_601’, ’Yojimbo’, 106, ’1961-06-16’, ’Drama’);


       The  third example uses the DEFAULT clause for the date columns rather
       than specifying a value:

       INSERT INTO films VALUES
	   (’UA502’, ’Bananas’, 105, DEFAULT, ’Comedy’, ’82 minutes’);
       INSERT INTO films (code, title, did, date_prod, kind)
	   VALUES (’T_601’, ’Yojimbo’, 106, DEFAULT, ’Drama’);


       This examples inserts several rows into table films from table tmp:

       INSERT INTO films SELECT * FROM tmp;


       This example inserts into array columns:

       -- Create an empty 3x3 gameboard for noughts-and-crosses
       -- (all of these commands create the same board)
       INSERT INTO tictactoe (game, board[1:3][1:3])
	   VALUES (1,’{{"","",""},{},{"",""}}’);
       INSERT INTO tictactoe (game, board[3][3])
	   VALUES (2,’{}’);
       INSERT INTO tictactoe (game, board)
	   VALUES (3,’{{,,},{,,},{,,}}’);


COMPATIBILITY
       INSERT conforms fully to the SQL standard.   Possible  limitations  of
       the query clause are documented under SELECT [select(7)].
