fbsql_db_status — Get the status for a given database
$database_name
, resource $link_identifier = ?
) : intGets the current status of the specified database.
database_nameThe 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。
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.
