INSERT INTOtable [ (column [, ...] ) ] { DEFAULT VALUES | VALUES ( {expression | DEFAULT } [, ...] ) |query }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 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 haveINSERT privilege to a table in order to insert into it. If you use thequery clause to insert rows from a query, you also need to haveSELECT privilege on any table used in the query.
The name (optionally schema-qualified) of an existing table.
The name of a column intable.
All columns will be filled with their default values.
An expression or value to assign tocolumn.
This column will be filled with its default value.
A query (SELECT statement) that supplies the rows to be inserted. Refer to theSELECT statement for a description of the syntax.
On successful completion, anINSERT command returns a command tag of the form
INSERToidcount
Thecount is the number of rows inserted. Ifcount is exactly one, and the target table has OIDs, thenoid is theOID assigned to the inserted row. Otherwiseoid is zero.
Insert a single row into tablefilms:
INSERT INTO films VALUES ('UA502', 'Bananas', 105, '1971-07-13', 'Comedy', '82 minutes');In this second example, the last columnlen 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 theDEFAULT 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 tablefilms from tabletmp:
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,'{{,,},{,,},{,,}}');INSERT conforms fully to the SQL standard. Possible limitations of thequery clause are documented underSELECT.
