sybase_select_db — Selects a Sybase database

bool sybase_select_db ( string $database_name [, resource $link_identifier ] )

sybase_select_db() sets the current active database on the server that's associated with the specified link identifier.

Every subsequent call to sybase_query() will be made on the active database.

database_name
link_identifier: If no link identifier is specified, the last opened link is assumed. If no link is open, the function will try to establish a link as if sybase_connect() was called, and use it.

如果成功则返回 TRUE，失败则返回 FALSE。
