INSERT
  SQL - Language Statements
 
 
  INSERT
  create new rows in a table
 
 
  INSERT
 
 
INSERT INTO table [ ( column [, ...] ) ]
    { DEFAULT VALUES | VALUES ( { expression | DEFAULT } [, ...] ) | query }
 
 
  Description
  
   INSERT inserts new rows into a table.
   One can insert a single row specified by value expressions,
   or several rows as a result of a query.
  
  
   The target column names may be listed in any order.  If no list of
   column names is given at all, the default is all the columns of the
   table in their declared order; or the first N> column
   names, if there are only N> columns supplied by the
   VALUES> clause or query>.  The values
   supplied by the VALUES> clause or query> are
   associated with the explicit or implicit column list left-to-right.
  
  
   Each column not present in the explicit or implicit column list will be
   filled with a default value, either its declared default value
   or null if there is none.
  
  
   If the expression for any 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.
      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.)
     
    
   
   
    DEFAULT VALUES
    
     
      All columns will be filled with their default values.
     
    
   
   
    expression
    
     
      An expression or value to assign to the corresponding column.
     
    
   
   
    DEFAULT
    
     
      The corresponding 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 example, the len column is
   omitted and therefore it will have the default value:
INSERT INTO films (code, title, did, date_prod, kind)
    VALUES ('T_601', 'Yojimbo', 106, '1961-06-16', 'Drama');
  
  
   This 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');
  
  
   To insert a row consisting entirely of default values:
INSERT INTO films DEFAULT VALUES;
  
  
   This example inserts some rows into table
   films from a table tmp_films
   with the same column layout as films:
INSERT INTO films SELECT * FROM tmp_films WHERE date_prod < '2004-05-07';
  
  
   This example inserts into array columns:
-- Create an empty 3x3 gameboard for noughts-and-crosses
INSERT INTO tictactoe (game, board[1:3][1:3])
    VALUES (1, '{{" "," "," "},{" "," "," "},{" "," "," "}}');
-- The subscripts in the above example aren't really needed
INSERT INTO tictactoe (game, board)
    VALUES (2, '{{X," "," "},{" ",O," "},{" ",X," "}}');
  
 
 
  Compatibility
  
   INSERT conforms to the SQL standard.  The case in
   which a column name list is omitted, but not all the columns are
   filled from the VALUES> clause or query>,
   is disallowed by the standard.
  
  
   Possible limitations of the query clause are documented under
   .
