pg_end_copy

(PHP 4 >= 4.0.3, PHP 5)

pg_end_copy与 PostgreSQL 后端同步

说明

bool pg_end_copy ([ resource $connection ] )

pg_end_copy() 在处理完 pg_put_line() 所执行的拷贝操作之后将 PostgreSQL 前端(通常为 web server 进程)与 PostgreSQL 服务器进行同步。pg_end_copy() 必须被调用,否则 PostgreSQL 服务器可能会和前端失去同步并报错。

参数

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().

返回值

成功时返回 TRUE, 或者在失败时返回 FALSE

范例

Example #1 pg_end_copy() 例子

<?php 
  $conn 
pg_pconnect("dbname=foo");
  
pg_query($conn"create table bar (a int4, b char(16), d float8)");
  
pg_query($conn"copy bar from stdin");
  
pg_put_line($conn"3\thello world\t4.5\n");
  
pg_put_line($conn"4\tgoodbye world\t7.11\n");
  
pg_put_line($conn"\.\n");
  
pg_end_copy($conn);
?>
