NAME¶
DBIx::Class::Storage::DBI::Cursor - Object representing a query cursor on a
resultset.
SYNOPSIS¶
my $cursor = $schema->resultset('CD')->cursor();
my $first_cd = $cursor->next;
DESCRIPTION¶
A Cursor represents a query cursor on a DBIx::Class::ResultSet object. It allows
for traversing the result set with "next", retrieving all results
with "all" and resetting the cursor with "reset".
Usually, you would use the cursor methods built into DBIx::Class::ResultSet to
traverse it. See "next" in DBIx::Class::ResultSet, "reset"
in DBIx::Class::ResultSet and "all" in DBIx::Class::ResultSet for
more information.

- Return Value: \@row_columns+
Returns a list of arrayrefs of column values for all rows in the
DBIx::Class::ResultSet.
