ingres_pconnect

(PHP 4 >= 4.0.2, PHP 5 <= 5.0.5, PECL ingres >= 1.0.0)

ingres_pconnectOpen a persistent connection to an Ingres database

说明

resource ingres_pconnect ([ string $database [, string $username [, string $password ]]] )

Open a persistent connection to an Ingres database.

There are only 2 differences between this function and ingres_connect() : First, when connecting, the function will first try to find a (persistent) link that's already opened with the same parameters. If one is found, an identifier for it will be returned instead of opening a new connection. Second, the connection to the Ingres server will not be closed when the execution of the script ends. Instead, the link will remain open for future use (ingres_close() will not close links established by ingres_pconnect()). This type of link is therefore called 'persistent'.

参数

database

The database name. Must follows the syntax [node_id::]dbname[/svr_class].

username

The Ingres user name.

password

The password associated with username .

返回值

Returns a Ingres link resource on success, or FALSE on failure.
