pg_last_oid

pg_last_oid

(PHP 4 >= 4.2.0, PHP 5)

pg_last_oid返回上一个对象的 oid

说明

int pg_last_oid ( resource $result )

pg_last_oid() 在上一条通过 pg_query() 发送的命令是 SQL INSERT 的情况下用来取得分配给所插入记录的 oid。如果存在有效的 oid 则返回一个正整数,如果出错或者上一条通过 pg_query() 发送的命令不是 INSERT 或者该 INSERT 失败则返回 FALSE

从 PostgreSQL 7.2 版开始 OID 字段成为可选项。如果一个表中没有定义 OID 字段,程序员必须用 pg_result_status() 函数来检查记录是否被成功插入。

Note:

本函数以前的名字为 pg_getlastoid()
