Fetches the value of a column named index_or_name (if it is a string), or of the ordinal column numbered index_or_name (if it is an integer) from the current row of the query result handle result. The decode binary flag operates in the same way as described under sqlite_fetch_array().
Use this function when you are iterating a large result set with many columns, or with columns that contain large amounts of data.
See also sqlite_fetch_string().
