ovrimos_fetch_into() is used to
fetch a row from the result set.
ovrimos_fetch_into() fetches a
row from the result set into 'result_array', which should be
passed by reference. Which row is fetched is determined by
the two last parameters. 'how' is one of 'Next' (default),
'Prev', 'First', 'Last', 'Absolute', corresponding to forward
direction from current position, backward direction from
current position, forward direction from the start, backward
direction from the end and absolute position from the start
(essentially equivalent to 'first' but needs 'rownumber').
Case is not significant. 'Rownumber' is optional except for
absolute positioning. Returns
TRUE or FALSE.
