INSERT INTO table [ ( column [, ...] ) ]
{ DEFAULT VALUES | VALUES ( { expression | DEFAULT } [, ...] ) | query }INSERT allows you to insert new rows into a table. You 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 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.
The name (optionally schema-qualified) of an existing table.
The name of a column in table. The column name can be qualified with a subfield name or array subscript, if needed. (Inserting into only some fields of a composite column leaves the other fields null.)
All columns will be filled with their default values.
An expression or value to assign to column.
This column will be filled with its default value.
A query (SELECT statement) that supplies the rows to be inserted. Refer to the SELECT statement for a description of the syntax.
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 ROWIDs, then oid is the ROWID assigned to the inserted row. Otherwise oid is zero.
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 example 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
-- (these commands create the same board)
INSERT INTO tictactoe (game, board[1:3][1:3])
VALUES (1,'{{"","",""},{"","",""},{"","",""}}');
INSERT INTO tictactoe (game, board)
VALUES (2,'{{,,},{,,},{,,}}');
INSERT conforms fully to the SQL standard. Possible limitations of the query clause are documented under SELECT.
