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 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 a single row into table films:

INSERT INTO films VALUES
    ('UA502','Bananas',105,'2025-08-08','Comedy',INTERVAL '82 minute');
   

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, DATE '2025-08-08', '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,'{{,,},{,,},{,,}}');
