bool maxdb_result::field_seek ( int
$fieldnr
)Sets the field cursor to the given offset. The next call to maxdb_fetch_field() will retrieve the field definition of the column associated with that offset.
Note:
To seek to the beginning of a row, pass an offset value of zero.
Returns:
maxdb_field_seek() returns previuos value of field cursor.
