INSERT (l)
Inserts new rows into a table
SYNOPSIS
INSERT INTO table [ ( column [, ...] ) ]
{ VALUES ( expression [, ...] ) | SELECT query }
table
The name of an existing table.
column
The name of a column in table .
expression
A valid expression or value to assign to column .
query
A valid query. Refer to the SELECT statement for a further description
of valid arguments.
INSERT oid 1
Message returned if only one row was inserted.
oid
is the numeric OID of the inserted row.
INSERT 0 #
Message returned if more than one rows were inserted.
#
is the number of rows inserted.
DESCRIPTION
INSERT allows one to insert new rows into a
class or table. One can insert
a single row at time or several rows as a result of a query.
The columns in the target list may be listed in any order.
Each column not present in the target list will be inserted
using a default value, either a declared DEFAULT value
or NULL. Postgres will reject the new
column if a NULL is inserted into a column declared NOT NULL.
If the expression for each column
is not of the correct data type, automatic type coercion will be
attempted.
You must have insert privilege to a table in order to append
to it, as well as select privilege on any table specified
in a WHERE clause.
USAGE
INSERT INTO films VALUES
('UA502','Bananas',105,'1971-07-13','Comedy',INTERVAL '82 minute');
In this second example the column date_prod 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, DATE '1961-06-16', 'Drama');
Insert a single row into table distributors; note that
only column name is specified, so the omitted
column did will be assigned its default value:
INSERT INTO distributors (name) VALUES ('British Lion');
Insert several rows into table films from table tmp:
INSERT INTO films SELECT * FROM tmp;
Insert into arrays (refer to
The PostgreSQL User's Guide for further
information about arrays):
-- Create an empty 3x3 gameboard for noughts-and-crosses
-- (all of these queries create the same board attribute)
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 is fully compatible with SQL92.
Possible limitations in features of the
query
clause are documented for
select(l).
