DBIx::SearchBuilder::Union - Deal with multiple SearchBuilder result sets as one
use DBIx::SearchBuilder::Union;
my $U = new DBIx::SearchBuilder::Union;
$U->add( $tickets1 );
$U->add( $tickets2 );
$U->GotoFirstItem;
while (my $z = $U->Next) {
printf "%5d %30.30s\n", $z->Id, $z->Subject;
}
This module is still experimental.
Implements a subset of the DBIx::SearchBuilder collection methods, but enough to do iteration over a bunch of results. Useful for displaying the results of two unrelated searches (for the same kind of objects) in a single list.
Create a new DBIx::SearchBuilder::Union object. No arguments.
Add a searchbuilder result (collection) to the Union object.
It must be the same type as the first object added.
Return the very first element of the Union (which is the first element of the first Collection). Also reset the current pointer to that element.
Return the next element in the Union.
Returns the last item
Returns the total number of elements in the Union'ed Collection
Starts the recordset counter over from the first item. the next time you call Next, you'll get the first item returned by the database, as if you'd just started iterating through the result set.
Returns true if the current row is the last record in the set.
Return a refernece to an array containing all objects found by this search.
Will destroy any positional state.
