fbsql_db_status

(PHP 4 >= 4.0.7, PHP 5, PHP 7)

fbsql_db_status — Get the status for a given database

说明

fbsql_db_status ( string $database_name [, resource $link_identifier ] ) : int

Gets the current status of the specified database.

参数

database_name

The database name.

link_identifier

由 fbsql_connect() 或 fbsql_pconnect() 返回的 FrontBase 链接标识符.

如可选并未指定，函数会尝试查找一个到 FrontBase 服务器的开放链接，且如没有找到这样的链接，会尝试通过不带参数调用 fbsql_connect() 来创建一个。

返回值

Returns an integer value with the current status. This can be one of the following constants:

  • FALSE - The exec handler for the host was invalid. This error will occur when the link_identifier connects directly to a database by using a port number. FBExec can be available on the server but no connection has been made for it.
  • FBSQL_UNKNOWN - The Status is unknown.
  • FBSQL_STOPPED - The database is not running. Use fbsql_start_db() to start the database.
  • FBSQL_STARTING - The database is starting.
  • FBSQL_RUNNING - The database is running and can be used to perform SQL operations.
  • FBSQL_STOPPING - The database is stopping.
  • FBSQL_NOEXEC - FBExec is not running on the server and it is not possible to get the status of the database.
