METHODS

array
my $array = $results->array;Fetch next row from "sth" and return it as an array reference. Note that "finish" needs to be called if you are not fetching all the possible rows.
# Process one row at a time
while (my $next = $results->array) {
say $next->[3];
}arrays
my $collection = $results->arrays;Fetch all rows from "sth" and return them as a Mojo::Collection object containing array references.
# Process all rows at once
say $results->arrays->reduce(sub { $a + $b->[3] }, 0);columns
my $columns = $results->columns;Return column names as an array reference.
# Names of all columns
say for @{$results->columns};expand
$results = $results->expand;Decode json and jsonb fields automatically to Perl values for all rows.
# Expand JSON
$results->expand->hashes->map(sub { $_->{foo}{bar} })->join("\n")->say;finish
$results->finish;Indicate that you are finished with "sth" and will not be fetching all the remaining rows.
hash
my $hash = $results->hash;Fetch next row from "sth" and return it as a hash reference. Note that "finish" needs to be called if you are not fetching all the possible rows.
# Process one row at a time
while (my $next = $results->hash) {
say $next->{money};
}hashes
my $collection = $results->hashes;Fetch all rows from "sth" and return them as a Mojo::Collection object containing hash references.
# Process all rows at once
say $results->hashes->reduce(sub { $a + $b->{money} }, 0);new
my $results = Mojo::Pg::Results->new;
my $results = Mojo::Pg::Results->new(sth => $sth);
my $results = Mojo::Pg::Results->new({sth => $sth});Construct a new Mojo::Pg::Results object.
rows
my $num = $results->rows;Number of rows.
text
my $text = $results->text;Fetch all rows from "sth" and turn them into a table with "tablify" in Mojo::Util.
