pg_put_line

(PHP 4 >= 4.0.3, PHP 5)pg_put_line -- Send a NULL-terminated string to PostgreSQL backend

Описание

bool pg_put_line (string data)

bool pg_put_line (resource connection, string data)

pg_put_line() sends a NULL-terminated string

to the PostgreSQL backend server. This is needed in conjunction

with PostgreSQL's COPY FROM command.

COPY is a high-speed data loading interface

supported by PostgreSQL. Data is passed in without being parsed,

and in a single transaction.

An alternative to using raw pg_put_line() commands

is to use pg_copy_from(). This is a far simpler

interface.

Замечание:

The application must explicitly send the two characters "\."

on the last line to indicate to the backend that it has finished

sending its data, before issuing pg_end_copy().

Внимание

Use of the pg_put_line() causes most large object

operations, including pg_lo_read() and

pg_lo_tell(), to subsequently fail. You can use

pg_copy_from() and pg_copy_to()

instead.

Список параметров

connection

PostgreSQL database connection resource. When

connection is not present, the default connection

is used. The default connection is the last connection made by

pg_connect() or pg_pconnect().

data

A line of text to be sent directly to the PostgreSQL backend. A NULL

terminator is added automatically.
