pg_put_line

pg_put_line — �� PostgreSQL ��˷����� NULL ��β���ַ���

˵��

pg_put_line ([ resource $connection ], string $data ) : bool

pg_put_line() �� PostgreSQL ��˷����������� NULL ��β���ַ������������ͨ�� PostgreSQL �� COPY ����������и��ٲ������ݡ���β�� NULL �ַ����Զ����롣

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.

Note:

Ӧ�ó��������ȷ���� pg_end_copy() ֮ǰ���һ�з��������ַ� "\." ������ָ���������ݽ�����

Warning

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.

����

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.
