Question

Actually I have executed the postgres query, assume that it has return the 10 rows. Now I am having that’s statement handler ( $sth ) .

print Dumper $sth->fetchrow_arrayref;
print Dumper $sth->fetchrow_arrayref;
print Dumper $sth->fetchrow_arrayref;
print Dumper $sth->fetchrow_arrayref;
print Dumper $sth->fetchrow_arrayref;

Now , I have fetched the 5 rows from the statement handler ( $sth .Now I want to get back
$sth reference pointer to 1th row…..

What should I do….?

Thanks

You cannot do that. Database cursors are designed to be read row by row, like a stream, without rewinding.

You need to copy the data into an array in memory if you want to jump around.

The easiest way would be to do

my $all_rows = $sth->fetchall_arrayref;

which gives you an arrayref, with one entry for each row, each row in the same format as fetchrow_arrayref produced.
