sqlite_unbuffered_query
(PHP 5)
sqlite_unbuffered_query(no version information, might be only in CVS)
SQLiteDatabase->unbufferedQuery -- Execute a query that does not prefetch and buffer all dataOpis
resource sqlite_unbuffered_query ( resource dbhandle, string query )resource sqlite_unbuffered_query ( string query, resource dbhandle )
Object oriented style (method):
class SQLiteDatabase {SQLiteUnbuffered unbufferedQuery ( string query )
}
sqlite_unbuffered_query() is identical to sqlite_query() except that the result that is returned is a sequential forward-only result set that can only be used to read each row, one after the other.
This function is ideal for generating things such as HTML tables where you only need to process one row at a time and don't need to randomly access the row data.
Notatka: Functions such as sqlite_seek(), sqlite_rewind(), sqlite_next(), sqlite_current(), and sqlite_num_rows() do not work on result handles returned from sqlite_unbuffered_query().
Parametry
- query
The query to be executed.
- dbhandle
The SQLite Database resource; returned from sqlite_open () when used procedurally. This parameter is not required when using the object-oriented method.
Notatka: Obsługiwane są dwie alternatywne składnie, dla zachowania kompatybilności z rozszerzeniami dla innych baz danych (takich jak MySQL). Preferowana jest pierwsza, gdzie dbhandle jest pierwszym parametrem funkcji.
Zwracane wartości
Returns a result handle or FALSE on failure.
sqlite_unbuffered_query() returns a sequential forward-only result set that can only be used to read each row, one after the other.
